Update Cascadia Code to 2007.01 (#6721)

Occasionally, we get users with corrupt PATH environment variables: they
can't lauch PowerShell, because for some reason it's dropped off their
PATH. We also get users who have stray applications named
`powershell.exe` just lying around in random system directories.

We can combat both of these issues by simply hardcoding where we expect
PowerShell and CMD to live. %SystemRoot% was chosen over %WINDIR%
because apparently (according to Stack Overflow), SystemPath is
read-only and WINDIR isn't.

Refs #6039, #4390, #4228 (powershell was not found)
Refs #4682, Fixes #6082 (stray powershell.exe)

(cherry picked from commit 2fc1ef04ce)

-By default the command suggestion will generate a file named based on your commit. That's generally ok as long as you add the file to your commit. Someone can reorganize it later.
-
-:warning: The command is written for posix shells. If it doesn't work for you, you can manually _add_ (one word per line) / _remove_ items to `expect.txt` and the `excludes.txt` files.
-
-If the listed items are:
-
-* ... **misspelled**, then please *correct* them instead of using the command.
-* ... *names*, please add them to `.github/actions/spelling/allow/names.txt`.
-* ... APIs, you can add them to a file in `.github/actions/spelling/allow/`.
-* ... just things you're using, please add them to an appropriate file in `.github/actions/spelling/expect/`.
-* ... tokens you only need in one place and shouldn't *generally be used*, you can add an item in an appropriate file in `.github/actions/spelling/patterns/`.
-
-See the `README.md` in each directory for more information.
-
-:microscope: You can test your commits **without** *appending* to a PR by creating a new branch with that extra change and pushing it to your fork. The [check-spelling](https://github.com/marketplace/actions/check-spelling) action will run in response to your **push** -- it doesn't require an open pull request. By using such a branch, you can limit the number of typos your peers see you make. :wink:

-
-If items relate to a ...
-* binary file (or some other file you wouldn't want to check at all).

-  Please add a file path to the `excludes.txt` file matching the containing file.
-
-  File paths are Perl 5 Regular Expressions - you can [test](
-https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your files.
-
-  `^` refers to the file's path from the root of the repository, so `^README\.md$` would exclude [README.md](
-../tree/HEAD/README.md) (on whichever branch you're using).
-
-* well-formed pattern.
-
-  If you can write a [pattern](https://github.com/check-spelling/check-spelling/wiki/Configuration-Examples:-patterns) that would match it,
-  try adding it to the `patterns.txt` file.
-
-  Patterns are Perl 5 Regular Expressions - you can [test](
-https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your lines.
-
-  Note that patterns can't match multiline strings.

-# New Json Utility API
-
-## Raw value conversion (GetValue)
-
-`GetValue` is a convenience helper that will either read a value into existing storage (type-deduced) or
-return a JSON value coerced into the specified type.
-
-When reading into existing storage, it returns a boolean indicating whether that storage was modified.
-
-If the JSON value cannot be converted to the specified type, an exception will be generated.
-
-```c++
-std::string one;
-std::optional<std::string> two;
-
-JsonUtils::GetValue(json, one);
-// one is populated or unchanged.
-
-JsonUtils::GetValue(json, two);
-// two is populated, nullopt or unchanged
-
-auto three = JsonUtils::GetValue<std::string>(json);
-// three is populated or zero-initialized
-
-auto four = JsonUtils::GetValue<std::optional<std::string>>(json);
-// four is populated or nullopt
-```
-
-## Key lookup (GetValueForKey)
-
-`GetValueForKey` follows the same rules as `GetValue`, but takes an additional key.
-It is assumed that the JSON value passed to GetValueForKey is of `object` type.
-
-```c++
-std::string one;
-std::optional<std::string> two;
-
-JsonUtils::GetValueForKey(json, "firstKey", one);
-// one is populated or unchanged.
-
-JsonUtils::GetValueForKey(json, "secondKey", two);
-// two is populated, nullopt or unchanged
-
-auto three = JsonUtils::GetValueForKey<std::string>(json, "thirdKey");
-// three is populated or zero-initialized
-
-auto four = JsonUtils::GetValueForKey<std::optional<std::string>>(json, "fourthKey");
-// four is populated or nullopt
-```
-
-## Rationale: Value-Returning Getters
-
-JsonUtils provides two types of `GetValue...`: value-returning and reference-filling.
-
-The reference-filling fixtures use type deduction so that a developer does not
-need to specify template parameters on every `GetValue` call. It excels at
-populating class members during deserialization.
-
-The value-returning fixtures, on the other hand, are very useful for partial
-deserialization and key detection when you do not need to deserialize an entire
-instance of a class or you need to reason about the presence of members.
-
-To provide a concrete example of the latter, consider:
-
-```c++
-if (const auto guid{ GetValueForKey<std::optional<GUID>>(json, "guid") }) 
-    // This condition is only true if there was a "guid" member in the provided JSON object.
-    // It can be accessed through *guid.
-}
-```
-
-If you are... | Use
---------------|-----
-Deserializing | `GetValue(..., storage)`
-Interrogating | `storage = GetValue<T>(...)`
-
-## Converting User-Defined Types
-
-All conversions are done using specializations of
-`JsonUtils::ConversionTrait<T>`.  To implement a converter for a user-defined
-type, you must implement a specialization of `JsonUtils::ConversionTrait<T>`.
-
-Every specialization over `T` must implement `static T FromJson(const Json::Value&)`
-and `static bool CanConvert(const Json::Value&)`.
-
-```c++
-struct MyCustomType { int val; };
-
-template<>
-struct ConversionTrait<MyCustomType>
-{
-    // This trait converts a string of the format "[0-9]" to a value of type MyCustomType.
-
-    static MyCustomType FromJson(const Json::Value& json)
-    {
-        return MyCustomType{ json.asString()[0] - '0' };
-    }
-
-    static bool CanConvert(const Json::Value& json)
-    {
-        return json.isString();
-    }
-};
-```
-
-### Converting User-Defined Enumerations
-
-Enumeration types represent a single choice out of multiple options.
-
-In a JSON data model, they are typically represented as strings.
-
-For parsing enumerations, JsonUtils provides the `JSON_ENUM_MAPPER` macro. It
-can be used to establish a converter that will take a set of known strings and
-convert them to values.
-
-```c++
-JSON_ENUM_MAPPER(CursorStyle)
-{
-    // pair_type is provided by ENUM_MAPPER.
-    JSON_MAPPINGS(5) = {
-        pair_type{ "bar", CursorStyle::Bar },
-        pair_type{ "vintage", CursorStyle::Vintage },
-        pair_type{ "underscore", CursorStyle::Underscore },
-        pair_type{ "filledBox", CursorStyle::FilledBox },
-        pair_type{ "emptyBox", CursorStyle::EmptyBox }
-    };
-};
-```
-
-If the enum mapper fails to convert the provided string, it will throw an
-exception.
-
-### Converting User-Defined Flag Sets
-
-Flags represent a multiple-choice selection. They are typically implemented as
-enums with bitfield values intended to be ORed together.
-
-In JSON, a set of flags may be represented by a single string (`"flagName"`) or
-an array of strings (`["flagOne", "flagTwo"]`).
-
-JsonUtils provides a `JSON_FLAG_MAPPER` macro that can be used to produce a
-specialization for a set of flags.
-
-Given the following flag enum,
-
-```c++
-enum class JsonTestFlags : int
-{
-    FlagOne = 1 << 0,
-    FlagTwo = 1 << 1
-};
-```
-
-You can register a flag mapper with the `JSON_FLAG_MAPPER` macro as follows:
-
-```c++
-JSON_FLAG_MAPPER(JsonTestFlags)
-{
-    JSON_MAPPINGS(2) = {
-        pair_type{ "flagOne", JsonTestFlags::FlagOne },
-        pair_type{ "flagTwo", JsonTestFlags::FlagTwo },
-    };
-};
-```
-
-The `FLAG_MAPPER` also provides two convenience definitions, `AllSet` and
-`AllClear`, that can be used to represent "all choices" and "no choices"
-respectively.
-
-```c++
-JSON_FLAG_MAPPER(JsonTestFlags)
-{
-    JSON_MAPPINGS(4) = {
-        pair_type{ "never", AllClear },
-        pair_type{ "flagOne", JsonTestFlags::FlagOne },
-        pair_type{ "flagTwo", JsonTestFlags::FlagTwo },
-        pair_type{ "always", AllSet },
-    };
-};
-```
-
-Because flag values are additive, `["always", "flagOne"]` will result in the
-same behavior as `"always"`.
-
-If the flag mapper encounters an unknown flag, it will throw an exception.
-
-If the flag mapper encounters a logical discontinuity such as `["never", "flagOne"]`
-(as in the above example), it will throw an exception.
-
-### Advanced Use
-
-`GetValue` and `GetValueForKey` can be passed, as their final arguments, any
-value whose type implements the same interface as `ConversionTrait<T>`--that
-is, `FromJson(const Json::Value&)` and `CanConvert(const Json::Value&)`.
-
-This allows for one-off conversions without a specialization of
-`ConversionTrait` or even stateful converters.
-
-#### Stateful Converter Sample
-
-```c++
-struct MultiplyingConverter {
-    int BaseValue;
-
-    bool CanConvert(const Json::Value&) { return true; }
-
-    int FromJson(const Json::Value& value)
-    {
-        return value.asInt() * BaseValue;
-    }
-};
-
-...
-
-Json::Value json{ 66 }; // A JSON value containing the number 66
-MultiplyingConverter conv{ 10 };
-
-auto v = JsonUtils::GetValue<int>(json, conv);
-// v is equal to 660.
-```
-
-## Behavior Chart
-
-### GetValue(T&) (type-deducing)
-
--|json type invalid|json null|valid
--|-|-|-
-`T`|❌ exception|🔵 unchanged|✔ converted
-`std::optional<T>`|❌ exception|🟨 `nullopt`|✔ converted
-
-### GetValue&lt;T&gt;() (returning)
-
--|json type invalid|json null|valid
--|-|-|-
-`T`|❌ exception|🟨 `T{}` (zero value)|✔ converted
-`std::optional<T>`|❌ exception|🟨 `nullopt`|✔ converted
-
-### GetValueForKey(T&) (type-deducing)
-
-GetValueForKey builds on the behavior set from GetValue by adding
-a "key not found" state. The remaining three cases are the same.
-
-val type|key not found|_json type invalid_|_json null_|_valid_
--|-|-|-|-
-`T`|🔵 unchanged|_❌ exception_|_🔵 unchanged_|_✔ converted_
-`std::optional<T>`|_🔵 unchanged_|_❌ exception_|_🟨 `nullopt`_|_✔ converted_
-
-### GetValueForKey&lt;T&gt;() (return value)
-
-val type|key not found|_json type invalid_|_json null_|_valid_
--|-|-|-|-
-`T`|🟨 `T{}` (zero value)|_❌ exception_|_🟨 `T{}` (zero value)_|_✔ converted_
-`std::optional<T>`|🟨 `nullopt`|_❌ exception_|_🟨 `nullopt`_|_✔ converted_
-
-### Future Direction
-
-These converters lend themselves very well to automatic _serialization_.

 ## Background Images and Icons

 Some Terminal settings allow you to specify custom background images and icons. It is recommended that custom images and icons are stored in system-provided folders and are referred to using the correct [URI Schemes](https://docs.microsoft.com/en-us/windows/uwp/app-resources/uri-schemes). URI Schemes provide a way to reference files independent of their physical paths (which may change in the future).

-# Advanced Tab Switcher
-
-## Abstract
-
-Currently the user is able to cycle through tabs on the tab bar. However, this horizontal cycling can be pretty inconvenient when the tab titles are long or when there are too many tabs on the tab bar. It could also get hard to see all your available tabs if the tab titles are long and your screen is small. In addition, there's a common use case to quickly switch between two tabs, e.g. when one tab is used as reference and the other is the actively worked-on tab. If the tabs are not right next to each other on the tab bar, it could be difficult to quickly swap between the two. Having the tabs displayed in Most Recently Used (MRU) order would help with this problem. It could also make the user experience better when there are a handful of tabs that are frequently used, but are nowhere near each other on the tab bar.
-
-Having a tab switcher UI, like the ones in Visual Studio and Visual Studio Code, could help with the tab experience. Presenting the tabs vertically in their own little UI allows the user to see more of the tabs at once, compared to scanning the tab row horizontally and scrolling left/right to find the tab you want. The tab order in those tab switchers are also in MRU order by default.
-
-To try to alleviate some of these user scenarios, we want to create a tab switcher similar to the ones found in VSCode and VS. This spec will cover the design of the switcher, and how a user would interact with the switcher. It would be primarily keyboard driven, and would give a pop-up display of a vertical list of tabs. The tab switcher would also be able to display the tabs in Most Recently Used (MRU) order.
-
-## Inspiration
-
-This was mainly inspired by the tab switcher that's found in Visual Studio Code and Visual Studio.
-
-VS Code's tab switcher appears directly underneath the tab bar.
-
-![Visual Studio Code Tab Switcher](img/VSCodeTabSwitcher.png)
-
-Visual Studio's tab switcher presents itself as a box in the middle of the editor.
-
-![Visual Studio Tab Switcher](img/VSTabSwitcher.png)
-
-In terms of navigating the switcher, both VSCode and Visual Studio behave very similarly. Both open with the press of <kbd>ctrl+tab</kbd> and dismiss on release of <kbd>ctrl</kbd>. They both also allow the user to select the tab with the mouse and with <kbd>enter</kbd>. <kbd>esc</kbd> and a mouse click outside of the switcher both dismiss the window as well.
-
-I'm partial towards looking like VSCode's Tab Switcher - specifically because it seems like both their Command Palette and Tab Switcher use the same UI. You can observe this by first bringing up the command palette, then hitting the keybinding to bring up the tab switcher. You'll notice that they're both using the same centered drop-down from the tab row. In fact, hitting the Tab Switcher keybinding in VSCode while the Command Palette is open simply auto fills the search box with "edit active", signifying that the user wants to select one of the tabs to edit, effectively "swapping" to the tab that's highlighted. 
-
-Since Terminal now has a command palette, it would be amazing to reuse that UI and simply fill it with the names of a user's currently open tabs!
-
-## Solution Design
-
-To extend upon the command palette, we simply need to create and maintain two Vector<Commands>, where each command will simply dispatch a `SwitchToTab` `ShortcutAction`. One vector will have the commands in tab row order, and the other will be in MRU order. They'll both have to be maintained along with our existing vector of tabs.  
-
-These vectors of commands can then be set as the commands to pull from in the command palette, and as long as the tab titles are available in these commands, the command palette will be able to naturally filter through the tabs as a user types in its search bar. Just like the command palette, a user will be able to navigate through the list of tabs with the arrow keys and pointer interactions. As part of this implementation, I can supplement these actions with "tab switcher specific" navigation keybindings that would only work if the command palette is in tab switcher mode. 
-
-The `TabSwitcherControl` will use `TerminalPage`'s `ShortcutActionDispatch` to dispatch a `SwitchToTab` `ShortcutAction`. This will eventually cause `TerminalPage::_OnTabSelectionChanged` to be called. We can update the MRU in this function to be sure that changing tabs from the TabSwitcher, clicking on a tab, or nextTab/prevTab-ing will keep the MRU up-to-date. Adding or closing tabs are handled in `_OpenNewTab` and `_CloseFocusedTab`, which will need to be modified to update the command vectors.
-
-## UI/UX Design
-
-The Tab Switcher will reuse a lot of the XAML code that's used in the command palette. This means it'll show up as a drop-down from the horizontal center of the tab row. It'll appear as a single overlay over the whole Terminal window. There will also be a search box on top of the list of tabs. Here's a rough mockup of how the command palette/tab switcher looks like:
-
-![Mockup Command Palette with Tab Titles](img/CommandPaletteExample.png)
-
-Each entry in the list will show the tab's titles and their assigned number for quick switching, and only one line will be highlighted to signify the tab that is currently selected. The top 9 tabs in the list are numbered for quick switching, and the rest of the tabs will simply have an empty space where a number would be.
-
-The list would look (roughly) like this:
-```
-1 foo (highlighted)
-2 boo
-3 Windows
-4 /c/Users/booboo
-5 Git Moo
-6 shoo
-7 /c/
-8 /d/
-9 /e/
-  /f/
-  /g/
-  /h/
-```
-
-The highlighted line can move up or down, and if the user moves up while the highlighted line is already at the top of the list, the highlight will wrap around to the bottom of the list. Similarly, it will wrap to the top if the highlight is at the bottom of the list and the user moves down.
-
-If there's more tabs than the UI can display, the list of tabs will scroll up/down as the user keeps iterating up/down. Even if some of the numbered tabs (the first 9 tabs) are not visible, the user can still press any number 1 through 9 to quick switch to that tab.
-
-To give an example of what happens after scrolling past the end, imagine a user is starting from the state in the mock above. The user then iterates down past the end of the visible list four times. The below mock shows the result.
-
-```
-5 Git Moo
-6 shoo
-7 /c/
-8 /d
-9 /e/
-  /f/
-  /g/
-  /h/
-  /i/
-  /j/
-  /k/
-  /l/ (highlighted)
-```
-
-The tabs designated by numbers 1 through 4 are no longer visible (but still quick-switchable), and the list now starts with "Git Moo", which is associated with number 5.
-
-### Using the Switcher
-
-#### Opening the Tab Switcher
-
-The user can press a keybinding named `tabSwitcher` to bring up the command palette UI with a list of tab titles.
-The user can also bring up the command palette first, and type a "tab switcher" prefix like "@" into the search bar to switch into "tab switcher mode".
-The user will be able to change it to whatever they like.
-There will also be an optional `anchor` arg that may be provided to this keybinding. 
-
-#### Keeping it open
-
-We use the term `anchor` to illustrate the idea that the UI stays visible as long as something is "anchoring" it down.
-
-Here's an example of how to set the `anchor` key in the settings:
-```
-  {"keys": ["ctrl+tab"], "command": {"action": "openTabSwitcher", "anchor": "ctrl" }}
-```
-
-This user provided the `anchor` key arg, and set it to <kbd>ctrl</kbd>. So, the user would open the UI with <kbd>ctrl+tab</kbd>, and as long as the user is holding <kbd>ctrl</kbd> down, the UI won't dismiss. The moment the user releases <kbd>ctrl</kbd>, the UI dismisses. The `anchor` key needs to be one of the keys in the `openTabSwitcher` keybinding. If it isn't, we'll display a warning dialog in this case saying that the `anchor` key isn't actually part of the keybinding, and the user might run into some weird behavior.
-
-If `openTabSwitcher` is not given an `anchor` key, the switcher will stay visible even after the release of the keybinding.
-
-#### Switching through Tabs
-
-The user will be able to navigate through the switcher with the following keybindings:
-
-- Switching Down: <kbd>tab</kbd> or <kbd>downArrow</kbd>
-- Switching Up: <kbd>shift+tab</kbd> or <kbd>upArrow</kbd>
-
-As the user is cycling through the tab list, the selected tab will be highlighted but the terminal won't actually switch focus to the selected tab. This also applies to pointer interaction. Hovering over an item with a mouse will highlight the item but not switch to the tab.
-
-#### Closing the Switcher and Bringing a Tab into Focus
-
-There are two _dismissal_ keybindings:
-
-1. <kbd>enter</kbd> : brings the currently selected tab into focus and dismisses the UI.
-2. <kbd>esc</kbd> : dismisses the UI without changing tab focus.
-
-The following are ways a user can dismiss the UI, _whether or not_ the `Anchor` key is provided to `openTabSwitcher`.
-
-1. The user can press a number associated with a tab to instantly switch to the tab and dismiss the switcher.
-2. The user can click on a tab to instantly switch to the tab and dismiss the switcher.
-3. The user can click outside of the UI to dismiss the switcher without bringing the selected tab into focus.
-4. The user can press any of the dismissal keybindings.
-
-If the `anchor` key is provided, then in addition to the above methods, the UI will dismiss upon the release of the `anchor` key.
-
-Pressing the `openTabSwitcher` keychord again will not close the switcher, it'll do nothing.
-
-### Most Recently Used Order
-
-We'll provide a setting that will allow the list of tabs to be presented in either _in-order_ (how the tabs are ordered on the tab bar), or _Most Recently Used Order_ (MRU). MRU means that the tab that the terminal most recently visited will be on the top of the list, and the tab that the terminal has not visited for the longest time will be on the bottom.
-
-There will be an argument for the `openTabSwitcher` action called `displayOrder`. This can be either `inOrder` or `mruOrder`. Making the setting an argument passed into `openTabSwitcher` would allow the user to have one keybinding to open an MRU Tab Switcher, and different one for the In-Order Tab Switcher. For example:
-```
-  {"keys": ["ctrl+tab"], "command": {"action": "openTabSwitcher", "anchor":"ctrl", "displayOrder":"mruOrder"}}
-  {"keys": ["ctrl+shift+p"], "command": {"action": "openTabSwitcher", "anchor":"ctrl", "displayOrder":"inOrder"}}
-```
-By default (when the arg isn't specified), `displayOrder` will be "mruOrder".
-
-### Numbered Tabs
-
-Similar to how the user can currently switch to a particular tab with a combination of keys such as <kbd>ctrl+shift+1</kbd>, we want to have the tab switcher provide a number to the first nine tabs (1-9) in the list for quick switching. If there are more than nine tabs in the list, then the rest of the tabs will not have a number assigned.
-
-## Capabilities
-
-### Accessibility
-
-- The tab switcher will be using WinUI, and so it'll be automatically linked to the UIA tree. This allows screen readers to find it, and so narrator will be able to navigate the switcher easily.
-- The UI is also fully keyboard-driven, with the option of using a mouse to interact with the UI.
-- When the tab switcher pops up, the focus immediately swaps to it.
-- For the sake of more contrast with the background, we could use a ThemeShadow to bring the UI closer to the user, making the focus clearer.
-
-### Security
-
-This shouldn't introduce any security issues.
-
-### Reliability
-
-How we're updating the MRU is something to watch out for since it triggers on a lot of tab interactions. However, I don't foresee the update taking long at all, and I can't imagine that users can create and delete tabs fast enough to matter.
-
-### Compatibility
-
-- The existing way of navigating horizontally through the tabs on the tab bar should not break.
-- These should also be separate keybindings from the keybindings associated with using the tab switcher.
-- When a user reorders their tabs on the tab bar, the MRU order remains unchanged. For example:
-  - Tab Bar:`[cmd(focused), ps, wsl]` and MRU:`[cmd, ps, wsl]`
-  - Reordered Tab Bar:`[wsl, cmd(focused), ps]` and MRU:`[cmd, ps, wsl]`
-
-### Performance, Power, and Efficiency
-
-## Potential Issues
-
-We'll need to be careful about how the UI is presented depending on different sizes of the terminal. We also should test how the UI looks as it's open and resizing is happening. Visual Studio's tab switcher is a fixed size, and is always in the middle. Even when the VS window is smaller than the tab switcher size, the tab switcher will show up larger than the VS window itself.
-
-![Small Visual Studio Without Tab Switcher](img/VSMinimumSize.png)
-![Small Visual Studio With Tab Switcher](img/VSMinimumSizeWithTabSwitcher.png)
-
-Visual Studio Code only allows the user to shrink the window until it hits a minimum width and height. This minimum width and height gives its tab switcher enough space to show a meaningful amount of information.
-
-![Small Visual Studio Code with Tab Switcher](img/VSCodeMinimumTabSwitcherSize.png)
-
-Terminal can't really replicate Visual Studio's version of the tab switcher in this situation. The TabSwitcher needs to be contained within the Terminal. So, if the TabSwitcher is always centered and has a percentage padding from the borders of the Terminal, it'll shrink as Terminal shrinks. Since the Terminal also has a minimum width, the switcher should always have enough space to be usefully visible.
-
-## Future considerations
-
-### Pane Navigation
-
-There was discussion in [#1502] that brought up the idea of pane navigation, inspired by tmux.
-
-![Tmux Tab and Pane Switching](img/tmuxPaneSwitching.png)
-
-Tmux allows the user to navigate directly to a pane and even give a preview of the pane. This would be extremely useful since it would allow the user to see a tree of their open tabs and panes. Currently there's no way to see what panes are open in each tab, so if you're looking for a particular pane, you'd need to cycle through your tabs to find it. If something like pane profile names (not sure what information to present in the switcher for panes) were presented in the TabSwitcher, the user could see all the panes in one box.
-
-To support pane navigation, the tab switcher can simply have another column to the right of the tab list to show a list of panes inside the selected tab. As the user iterates through the tab list, they can simply hit right to dig deeper into the tab's panes, and hit left to come back to the tab list. Each tab's list of panes will be MRU or in-order, depending on which `displayOrder` arg was provided to the `openTabSwitcher` keybinding.
-
-Pane navigation is a clear next step to build on top of the tab switcher, but this spec will specifically deal with just tab navigation in order to keep the scope tight. The tab switcher implementation just needs to allow for pane navigation to be added in later.
-
-### Tab Preview on Hover
-
-With this feature, having a tab highlighted in the switcher would make the Terminal display that tab as if it switched to it. I believe currently there is no way to set focus to a tab in a "preview" mode. This is important because MRU updates whenever a tab is focused, but we don't want the MRU to update on a preview. Given that this feature is a "nice thing to have", I'll leave it for
-after the tab switcher has landed.

-# Command Palette
-
-## Abstract
-
-This spec covers the addition of a "command palette" to the Windows Terminal.
-The Command Palette is a GUI that the user can activate to search for and
-execute commands. Beneficially, the command palette allows the user to execute
-commands _even if they aren't bound to a keybinding_.
-
-## Inspiration
-
-This feature is largely inspired by the "Command Palette" in text editors like
-VsCode, Sublime Text and others.
-
-This spec was initially drafted in [a
-comment](https://github.com/microsoft/terminal/issues/2046#issuecomment-514219791)
-in [#2046]. That was authored during the annual Microsoft Hackathon, where I
-proceeded to prototype the solution. This spec is influenced by things I learned
-prototyping.
-
-Initially, the command palette was designed simply as a method for executing
-certain actions that the user pre-defined. With the addition of [commandline
-arguments](https://github.com/microsoft/terminal/issues/4632) to the Windows
-Terminal in v0.9, we also considered what it might mean to be able to have the
-command palette work as an effective UI not only for dispatching pre-defined
-commands, but also `wt.exe` commandlines to the current terminal instance.
-
-## Solution Design
-
-Fundamentally, we need to address two different modes of using the command palette:
-* In the first mode, the command palette can be used to quickly look up
-  pre-defined actions and dispatch them. We'll refer to this as "Action Mode".
-* The second mode allows the user to run `wt` commandline commands and have them
-  apply immediately to the current Terminal window. We'll refer to this as
-  "commandline mode".
-
-Both these options will be discussed in detail below.
-
-### Action Mode
-
-We'll introduce a new top-level array to the user settings, under the key
-`commands`. `commands` will contain an array of commands, each with the
-following schema:
-
-```js
-{
-    "name": string|object,
-    "action": string|object,
-    "icon": string
-}
-```
-
-Command names should be human-friendly names of actions, though they don't need
-to necessarily be related to the action that it fires. For example, a command
-with `newTab` as the action could have `"Open New Tab"` as the name.
-
-The command will be parsed into a new class, `Command`:
-
-```c++
-class Command
-{
-    winrt::hstring Name();
-    winrt::TerminalApp::ActionAndArgs ActionAndArgs();
-    winrt::hstring IconSource();
-}
-```
-
-We'll add another structure in GlobalAppSettings to hold all these actions. It
-will just be a `std::vector<Command>` in `GlobalAppSettings`.
-
-We'll need app to be able to turn this vector into a `ListView`, or similar, so
-that we can display this list of actions. Each element in the view will be
-intrinsically associated with the `Command` object it's associated with. In
-order to support this, we'll make `Command` a winrt type that implements
-`Windows.UI.Xaml.Data.INotifyPropertyChanged`. This will let us bind the XAML
-element to the winrt type.
-
-When an element is clicked on in the list of commands, we'll raise the event
-corresponding to that `ShortcutAction`. `AppKeyBindings` already does a great
-job of dispatching `ShortcutActions` (and their associated arguments), so we'll
-re-use that. We'll pull the basic parts of dispatching `ActionAndArgs`
-callbacks into another class, `ShortcutActionDispatch`, with a single
-`DoAction(ActionAndArgs)` method (and events for each action).
-`AppKeyBindings` will be initialized with a reference to the
-`ShortcutActionDispatch` object, so that it can call `DoAction` on it.
-Additionally, by having a singular `ShortcutActionDispatch` instance, we won't
-need to re-hook up the ShortcutAction keybindings each time we re-load the
-settings.
-
-In `TerminalPage`, when someone clicks on an item in the list, we'll get the
-`ActionAndArgs` associated with that list element, and call `DoAction` on
-the app's `ShortcutActionDispatch`. This will trigger the event handler just the
-same as pressing the keybinding.
-
-#### Commands for each profile?
-
-[#3879] Is a request for being able to launch a profile directly, via the
-command palette. Essentially, the user will type the name of a profile, and hit
-enter to launch that profile. I quite like this idea, but with the current spec,
-this won't work great. We'd need to manually have one entry in the command
-palette for each profile, and every time the user adds a profile, they'd need to
-update the list of commands to add a new entry for that profile as well.
-
-This is a fairly complicated addition to this feature, so I'd hold it for
-"Command Palette v2", though I believe it's solution deserves special
-consideration from the outset.
-
-I suggest that we need a mechanism by which the user can specify a single
-command that would be expanded to one command for every profile in the list of
-profiles. Consider the following sample:
-
-```json
-    "commands": [
-        {
-            "expandOn": "profiles",
-            "icon": "${profile.icon}",
-            "name": "New Tab with ${profile.name}",
-            "command": { "action": "newTab", "profile": "${profile.name}" }
-        },
-        {
-            "expandOn": "profiles",
-            "icon": "${profile.icon}",
-            "name": "New Vertical Split with ${profile.name}",
-            "command": { "action": "splitPane", "split":"vertical", "profile": "${profile.name}" }
-        }
-    ],
-```
-
-In this example:
-* The `"expandOn": "profiles"` property indicates that each command should be
-  repeated for each individual profile.
-* The `${profile.name}` value is treated as "when expanded, use the given
-  profile's name". This allows each command to use the `name` and `icon`
-  properties of a `Profile` to customize the text of the command.
-
-To ensure that this works correctly, we'll need to make sure to expand these
-commands after all the other settings have been parsed, presumably in the
-`Validate` phase. If we do it earlier, it's possible that not all the profiles
-from various sources will have been added yet, which would lead to an incomplete
-command list.
-
-We'll need to have a placeholder property to indicate that a command should be
-expanded for each `Profile`. When the command is first parsed, we'll leave the
-format strings `${...}` unexpanded at this time. Then, in the validate phase,
-when we encounter a `"expandOn": "profiles"` command, we'll remove it from the
-list, and use it as a prototype to generate commands for every `Profile` in our
-profiles list. We'll do a string find-and-replace on the format strings to
-replace them with the values from the profile, before adding the completed
-command to the list of commands.
-
-Of course, how does this work with localization? Considering the [section
-below](#localization), we'd update the built-in commands to the following:
-
-```json
-    "commands": [
-        {
-            "iterateOn": "profiles",
-            "icon": "${profile.icon}",
-            "name": { "key": "NewTabWithProfileCommandName" },
-            "command": { "action": "newTab", "profile": "${profile.name}" }
-        },
-        {
-            "iterateOn": "profiles",
-            "icon": "${profile.icon}",
-            "name": { "key": "NewVerticalSplitWithProfileCommandName" },
-            "command": { "action": "splitPane", "split":"vertical", "profile": "${profile.name}" }
-        }
-    ],
-```
-
-In this example, we'll look up the `NewTabWithProfileCommandName` resource when
-we're first parsing the command, to find a string similar to `"New Tab with
-${profile.name}"`. When we then later expand the command, we'll see the
-`${profile.name}` bit from the resource, and expand that like we normally would.
-
-Trickily, we'll need to make sure to have a helper for replacing strings like
-this that can be used for general purpose arg parsing. As you can see, the
-`profile` property of the `newTab` command also needs the name of the profile.
-Either the command validation will need to go through and update these strings
-manually, or we'll need another of enabling these `IActionArgs` classes to fill
-those parameters in based on the profile being used. Perhaps the command
-pre-expansion could just stash the json for the action, then expand it later?
-This implementation detail is why this particular feature is not slated for
-inclusion in an initial Command Palette implementation.
-
-From initial prototyping, it seems like the best solution will be to stash the
-command's original json around when parsing an expandable command like the above
-examples. Then, we'll handle the expansion in the settings validation phase,
-after all the profiles and color schemes have been loaded.
-
-For each profile, we'll need to replace all the instances in the original json
-of strings like `${profile.name}` with the profile's name to create a new json
-string. We'll attempt to parse that new string into a new command to add to the
-list of commands.
-
-### Commandline Mode
-
-One of our more highly requested features is the ability to run a `wt.exe`
-commandline in the current WT window (see [#4472]). Typically, users want the
-ability to do this straight from whatever shell they're currently running.
-However, we don't really have an effective way currently to know if WT is itself
-being called from another WT instance, and passing those arguments to the
-hosting WT. Furthermore, in the long term, we see that feature as needing the
-ability to not only run commands in the current WT window, but an _arbitrary_ WT
-window.
-
-The Command Palette seems like a natural fit for a stopgap measure while we
-design the correct way to have a `wt` commandline apply to the window it's
-running in.
-
-In Commandline Mode, the user can simply type a `wt.exe` commandline, and when
-they hit enter, we'll parse the commandline and dispatch it _to the current
-window_. So if the user wants to open a new tab, they could type `new-tab` in
-Commandline Mode, and it would open a new tab in the current window. They're
-also free to chain multiple commands like they can with `wt` from a shell - by
-entering something like `split-pane -p "Windows PowerShell" ; split-pane -H
-wsl.exe`, the terminal would execute two `SplitPane` actions in the currently
-focused pane, creating one with the "Windows PowerShell" profile and another
-with the default profile running `wsl` in it.
-
-## UI/UX Design
-
-We'll add another action that can be used to toggle the visibility of the
-command palette. Pressing that keybinding will bring up the command palette. We
-should make sure to add a argument to this action that specifies whether the
-palette should be opened directly in Action Mode or Commandline Mode.
-
-When the command palette appears, we'll want it to appear as a single overlay
-over all of the panes of the Terminal. The drop-down will be centered
-horizontally, dropping down from the top (from the tab row). When commands are
-entered, it will be implied that they are delivered to the focused terminal
-pane. This will help avoid two problematic scenarios that could arise from
-having the command palette attached to a single pane:
-  * When attached to a single pane, it might be very easy for the UI to quickly
-    become cluttered, especially at smaller pane sizes.
-  * This avoids the "find the overlay problem" which is common in editors like
-    VS where the dialog appears attached to the active editor pane.
-
-The palette will consist of two main UI elements: a text box for
-entering/searching for commands, and in action mode, a list of commands.
-
-### Action Mode
-
-The list of commands will be populated with all the commands by default. Each
-command will appear like a `MenuFlyoutItem`, with an icon at the left (if it has
-one) and the name visible. When opened, the palette will automatically highlight
-the first entry in the list.
-
-The user can navigate the list of entries with the arrow keys. Hitting enter
-will close the palette and execute the action that's highlighted. Hitting escape
-will dismiss the palette, returning control to the terminal. When the palette is
-closed for any reason (executing a command, dismissing with either escape or the
-`toggleCommandPalette` keybinding), we'll clear out any search text from the
-palette, so the user can start fresh again.
-
-We'll also want to enable the command palette to be filterable, so that the user
-can type the name of a command, and the command palette will automatically
-filter the list of commands. This should be more powerful then just a simple
-string compare - the user should be able to type a search string, and get all
-the commands that match a "fuzzy search" for that string. This will allow users
-to find the command they're looking for without needing to type the entire
-command.
-
-For example, consider the following list of commands:
-
-```json
-    "commands": [
-        { "icon": null, "name": "New Tab", "action": "newTab" },
-        { "icon": null, "name": "Close Tab", "action": "closeTab" },
-        { "icon": null, "name": "Close Pane", "action": "closePane" },
-        { "icon": null, "name": "[-] Split Horizontal", "action": { "action": "splitPane", "split": "horizontal" } },
-        { "icon": null, "name": "[ | ] Split Vertical", "action": { "action": "splitPane", "split": "vertical" } },
-        { "icon": null, "name": "Next Tab", "action": "nextTab" },
-        { "icon": null, "name": "Prev Tab", "action": "prevTab" },
-        { "icon": null, "name": "Open Settings", "action": "openSettings" },
-        { "icon": null, "name": "Open Media Controls", "action": "openTestPane" }
-    ],
-```
-
-* "open" should return both "**Open** Settings" and "**Open** Media Controls".
-* "Tab" would return "New **Tab**", "Close **Tab**", "Next **Tab**" and "Prev
-  **Tab**".
-* "P" would return "Close **P**ane", "[-] S**p**lit Horizontal", "[ | ]
-  S**p**lit Vertical", "**P**rev Tab", "O**p**en Settings" and "O**p**en Media
-  Controls".
-* Even more powerfully, "sv" would return "[ | ] Split Vertical" (by matching
-  the **S** in "Split", then the **V** in "Vertical"). This is a great example
-  of how a user could execute a command with very few keystrokes.
-
-As the user types, we should **bold** each matching character in the command
-name, to show how their input correlates to the results on screen.
-
-Additionally, it will be important for commands in the action list to display
-the keybinding that's bound to them, if there is one.
-
-### Commandline Mode
-
-Commandline mode is much simpler. In this mode, we'll simply display a text input,
-similar to the search box that's rendered for Action Mode. In this box, the
-user will be able to type a `wt.exe` style commandline. The user does not need
-to start this commandline with `wt` (or `wtd`, etc) - since we're already
-running in WT, the user shouldn't really need to repeat themselves.
-
-When the user hits <kbd>enter</kbd>, we'll attempt to parse the commandline. If
-we're successful in parsing the commandline, we can close the palette and
-dispatch the commandline. If the commandline had errors, we should reveal a text
-box with an error message below the text input. We'll leave the palette open
-with their entered command, so they can edit the commandline and try again. We
-should _probably_ leave the message up for a few seconds once they've begun
-editing the commandline, but eventually hide the message (ideally with a motion
-animation).
-
-### Switching Between Modes
-
-**TODO**: This is a topic for _discussion_.
-
-How do we differentiate Action Mode from Commandline Mode?
-
-I think there should be a character that the user types that switches the mode.
-This is reminiscent of how the command palette works in applications like VsCode
-and Sublime Text. The same UI is used for a number of functions. In the case of
-VsCode, when the user opens the palette, it's initially in a "navigate to file"
-mode. When the user types the prefix character `@`, the menu seamlessly switches
-to a "navigate to symbol mode". Similarly, users can use `:` for "go to line"
-and `>` enters an "editor command" mode.
-
-I believe we should use a similarly implemented UI. The UI would be in one of
-the two modes by default, and typing the prefix character would enter the other
-mode. If the user deletes the prefix character, then we'd switch back into the
-default mode.
-
-When the user is in Action Mode vs Commandline mode, if the input is empty
-(besides potentially the prefix character), we should probably have some sort of
-placeholder text visible to indicate which mode the user is in. Something like
-_"Enter a command name..."_ for action mode, or _"Type a wt commandline..."_ for
-commandline mode.
-
-Initially, I favored having the palette in Action Mode by default, and typing a
-`:` prefix to enter Commandline Mode. This is fairly similar to how tmux's
-internal command prompt works, which is bound to `<prefix>-:` by default.
-
-If we wanted to remain _similar_ to VsCode, we'd have no prefix character be the
-Commandline Mode, and `>` would enter the Action mode. I'd think that might
-actually be _backwards_ from what I'd expect, with `>` being the default
-character for the end of the default `cmd` `%PROMPT%`.
-
-**FOR DISCUSSION** What option makes the most sense to the team? I'm leaning
-towards the VsCode style (where Action='>', Commandline='') currently.
-
-Enabling the user to configure this prefix is discussed below in "[Future
-Considerations](#Configuring-The-ActionCommandline-Mode-Prefix)".
-
-### Layering and "Unbinding" Commands
-
-As we'll be providing a list of default commands, the user will inevitably want
-to change or remove some of these default commands.
-
-Commands should be layered based upon the _evaluated_ value of the "name"
-property. Since the default commands will all use localized strings in the
-`"name": { "key": "KeyName" }` format, the user should be able to override the
-command based on the localized string for that command.
-
-So, assuming that `NewTabCommandName` is evaluated as "Open New Tab", the
-following command
-```json
-{ "icon": null, "name": { "key": "NewTabCommandName" }, "action": "newTab" },
-```
-
-Could be overridden with the command:
-```json
-{ "icon": null, "name": "Open New Tab", "action": "splitPane" },
-```
-
-Similarly, if the user wants to remove that command from the command palette,
-they could set the action to `null`:
-
-```json
-{ "icon": null, "name": "Open New Tab", "action": null },
-```
-
-This will remove the command from the command list.
-
-## Capabilities
-
-### Accessibility
-
-As the entire command palette will be a native XAML element, it'll automatically
-be hooked up to the UIA tree, allowing for screen readers to naturally find it.
- * When the palette is opened, it will automatically receive focus.
- * The terminal panes will not be able to be interacted with while the palette
-   is open, which will help keep the UIA tree simple while the palette is open.
-
-### Security
-
-This should not introduce any _new_ security concerns. We're relying on the
-security of jsoncpp for parsing json. Adding new keys to the settings file
-will rely on jsoncpp's ability to securely parse those json values.
-
-### Reliability
-
-We'll need to make sure that invalid commands are ignored. A command could be
-invalid because:
-* it has a null `name`, or a name with the empty string for a value.
-* it has a null `action`, or an action specified that's not an actual
-  `ShortcutAction`.
-
-We'll ignore invalid commands from the user's settings, instead of hard
-crashing. I don't believe this is a scenario that warrants an error dialog to
-indicate to the user that there's a problem with the json.
-
-### Compatibility
-
-We will need to define default _commands_ for all the existing keybinding
-commands. With #754, we could add all the actions (that make sense) as commands
-to the commands list, so that everyone wouldn't need to define them manually.
-
-### Performance, Power, and Efficiency
-
-We'll be adding a few extra XAML elements to our tree which will certainly
-increase our runtime memory footprint while the palette is open.
-
-We'll additionally be introducing a few extra json values to parse, so that could
-increase our load times (though this will likely be negligible).
-
-## Potential Issues
-
-This will first require the work in [#1205] to work properly. Right now we
-heavily lean on the "focused" element to determine which terminal is "active".
-However, when the command palette is opened, focus will move out of the terminal
-control into the command palette, which leads to some hard to debug crashes.
-
-Additionally, we'll need to ensure that the "fuzzy search" algorithm proposed
-above will work for non-english languages, where a single character might be
-multiple `char`s long. As we'll be using a standard XAML text box for input, we
-won't need to worry about handling the input ourselves.
-
-### Localization
-
-Because we'll be shipping a set of default commands with the terminal, we should
-make sure that list of commands can be localizable. Each of the names we'll give
-to the commands should be locale-specific.
-
-To facilitate this, we'll use a special type of object in JSON that will let us
-specify a resource name in JSON. We'll use a syntax like the following to
-suggest that we should load a string from our resources, as opposed to using the
-value from the file:
-
-```json
-    "commands": [
-        { "icon": null, "name": { "key": "NewTabCommandName" }, "action": "newTab" },
-        { "icon": null, "name": { "key": "CloseTabCommandKey" }, "action": "closeTab" },
-        { "icon": null, "name": { "key": "ClosePaneCommandKey" }, "action": "closePane" },
-        { "icon": null, "name": { "key": "SplitHorizontalCommandKey" }, "action": { "action": "splitPane", "split": "horizontal" } },
-        { "icon": null, "name": { "key": "SplitVerticalCommandKey" }, "action": { "action": "splitPane", "split": "vertical" } },
-        { "icon": null, "name": { "key": "NextTabCommandKey" }, "action": "nextTab" },
-        { "icon": null, "name": { "key": "PrevTabCommandKey" }, "action": "prevTab" },
-        { "icon": null, "name": { "key": "OpenSettingsCommandKey" }, "action": "openSettings" },
-    ],
-```
-
-We'll check at parse time if the `name` property is a string or an object. If
-it's a string, we'll treat that string as the literal text. Otherwise, if it's
-an object, we'll attempt to use the `key` property of that object to look up a
-string from our `ResourceDictionary`. This way, we'll be able to ship localized
-strings for all the built-in commands, while also allowing the user to easily
-add their own commands.
-
-During the spec review process, we considered other options for localization as
-well. The original proposal included options such as having one `defaults.json`
-file per-locale, and building the Terminal independently for each locale. Those
-were not really feasible options, so we instead settled on this solution, as it
-allowed us to leverage the existing localization support provided to us by the
-platform.
-
-The `{ "key": "resourceName" }` solution proposed here was also touched on in
-[#5280].
-
-### Proposed Defaults
-
-These are the following commands I'm proposing adding to the command palette by
-default. These are largely the actions that are bound by default.
-
-```json
-"commands": [
-    { "icon": null, "name": { "key": "NewTabCommandKey" }, "action": "newTab" },
-    { "icon": null, "name": { "key": "DuplicateTabCommandKey" }, "action": "duplicateTab" },
-    { "icon": null, "name": { "key": "DuplicatePaneCommandKey" }, "action": { "action": "splitPane", "split":"auto", "splitMode": "duplicate" } },
-    { "icon": null, "name": { "key": "SplitHorizontalCommandKey" }, "action": { "action": "splitPane", "split": "horizontal" } },
-    { "icon": null, "name": { "key": "SplitVerticalCommandKey" }, "action": { "action": "splitPane", "split": "vertical" } },
-
-    { "icon": null, "name": { "key": "CloseWindowCommandKey" }, "action": "closeWindow" },
-    { "icon": null, "name": { "key": "ClosePaneCommandKey" }, "action": "closePane" },
-
-    { "icon": null, "name": { "key": "OpenNewTabDropdownCommandKey" }, "action": "openNewTabDropdown" },
-    { "icon": null, "name": { "key": "OpenSettingsCommandKey" }, "action": "openSettings" },
-
-    { "icon": null, "name": { "key": "FindCommandKey" }, "action": "find" },
-
-    { "icon": null, "name": { "key": "NextTabCommandKey" }, "action": "nextTab" },
-    { "icon": null, "name": { "key": "PrevTabCommandKey" }, "action": "prevTab" },
-
-    { "icon": null, "name": { "key": "ToggleFullscreenCommandKey" }, "action": "toggleFullscreen" },
-
-    { "icon": null, "name": { "key": "CopyTextCommandKey" }, "action": { "action": "copy", "singleLine": false } },
-    { "icon": null, "name": { "key": "PasteCommandKey" }, "action": "paste" },
-
-    { "icon": null, "name": { "key": "IncreaseFontSizeCommandKey" }, "action": { "action": "adjustFontSize", "delta": 1 } },
-    { "icon": null, "name": { "key": "DecreaseFontSizeCommandKey" }, "action": { "action": "adjustFontSize", "delta": -1 } },
-    { "icon": null, "name": { "key": "ResetFontSizeCommandKey" }, "action": "resetFontSize"  },
-
-    { "icon": null, "name": { "key": "ScrollDownCommandKey" }, "action": "scrollDown" },
-    { "icon": null, "name": { "key": "ScrollDownPageCommandKey" }, "action": "scrollDownPage" },
-    { "icon": null, "name": { "key": "ScrollUpCommandKey" }, "action": "scrollUp" },
-    { "icon": null, "name": { "key": "ScrollUpPageCommandKey" }, "action": "scrollUpPage" }
-]

-
-## Addenda
-
-This spec also has a follow-up spec which introduces further changes upon this
-original draft. Please also refer to:
-
-* June 2020: Unified keybindings and commands, and synthesized action names.
-
-## Future considerations
-
-* Commands will provide an easy point for allowing an extension to add its
-  actions to the UI, without forcing the user to bind the extension's actions to
-  a keybinding
-* Also discussed in [#2046] was the potential for adding a command that inputs a
-  certain commandline to be run by the shell. I felt that was out of scope for
-  this spec, so I'm not including it in detail. I believe that would be
-  accomplished by adding a `inputCommand` action, with two args: `commandline`,
-  a string, and `suppressNewline`, an optional bool, defaulted to false. The
-  `inputCommand` action would deliver the given `commandline` as input to the
-  connection, followed by a newline (as to execute the command).
-  `suppressNewline` would prevent the newline from being added. This would work
-  relatively well, so long as you're sitting at a shell prompt. If you were in
-  an application like `vim`, this might be handy for executing a sequence of
-  vim-specific keybindings. Otherwise, you're just going to end up writing a
-  commandline to the buffer of vim. It would be weird, but not unexpected.
-* Additionally mentioned in [#2046] was the potential for profile-scoped
-  commands. While that's a great idea, I believe it's out of scope for this
-  spec.
-* Once [#754] lands, we'll need to make sure to include commands for each action
-  manually in the default settings. This will add some overhead that the
-  developer will need to do whenever they add an action. That's unfortunate, but
-  will be largely beneficial to the end user.
-* We could theoretically also display the keybinding for a certain command in
-  the `ListViewItem` for the command. We'd need some way to correlate a
-  command's action to a keybinding's action. This could be done in a follow-up
-  task.
-* We might want to alter the fuzzy-search algorithm, to give higher precedence
-  in the results list to commands with more consecutive matching characters.
-  Alternatively we could give more weight to commands where the search matched
-  the initial character of words in the command.
-  - For example: `ot` would give more weight to "**O**pen **T**ab" than
-    "**O**pen Se**t**tings").
-* We may want to add a button to the New Tab Button's dropdown to "Show Command
-  Palette". I'm hesitant to keep adding new buttons to that UI, but the command
-  palette is otherwise not highly discoverable.
-  - We could add another button to the UI to toggle the visibility of the
-    command palette. This was the idea initially proposed in [#2046].
-  - For both these options, we may want a global setting to hide that button, to
-    keep the UI as minimal as possible.
-* [#1571] is a request for customizing the "new tab dropdown" menu. When we get
-  to discussing that design, we should consider also enabling users to add
-  commands from their list of commands to that menu as well.
-  - This is included in the spec in [#5888].
-* I think it would be cool if there was a small timeout as the user was typing
-  in commandline mode before we try to auto-parse their commandline, to check
-  for errors. Might be useful to help sanity check users. We can always parse
-  their `wt` commandlines safely without having to execute them.
-* It would be cool if the commands the user typed in Commandline Mode could be
-  saved to a history of some sort, so they could easily be re-entered.
-  - It would be especially cool if it could do this across launches.
-    - We don't really have any way of storing transient data like that in the
-      Terminal, so that would need to be figured out first.
-  - Typically the Command Palette is at the top of the view, with the
-    suggestions below it, so navigating through the history would be _backwards_
-    relative to a normal shell.
-* Perhaps users will want the ability to configure which side of the window the
-  palette appears on?
-  - This might fit in better with [#3327].
-* [#3753] is a pull request that covers the addition of an "Advanced Tab
-  Switcher". In an application like VsCode, their advanced tab switcher UI is
-  similar to their command palette UI. It might make sense that the user could
-  use the command palette UI to also navigate to active tabs or panes within the
-  terminal, by control name. We've already outlined how the Command Palette
-  could operate in "Action Mode" or "Commandline Mode" - we could also add
-  "Navigate Mode" on `@`, for navigating between tabs or panes.
-  - The tab switcher could probably largely re-use the command palette UI, but
-    maybe hide the input box by default.
-* We should make sure to add a setting in the future that lets the user opt-in
-  to showing most-recently used commands _first_ in the search order, and
-  possibly even pre-populating the search box with whatever their last entry
-  was.
-  - I'm thinking these are two _separate_ settings.
-
-### Nested Commands
-
-Another idea for a future spec is the concept of "nested commands", where a
-single command has many sub-commands. This would hide the children commands from
-the entire list of commands, allowing for much more succinct top-level list of
-commands, and allowing related commands to be grouped together.
-- For example, I have a text editor plugin that enables rendering markdown to a
-  number of different styles. To use that command in my text editor, first I hit
-  enter on the "Render Markdown..." command, then I select which style I want to
-  render to, in another list of options. This way, I don't need to have three
-  options for "Render Markdown to github", "Render Markdown to gitlab", all in
-  the top-level list.
-- We probably also want to allow a nested command set to be evaluated at runtime
-  somehow. Like if we had a "Open New Tab..." command that then had a nested
-  menu with the list of profiles.
-
-The above might be able to be expressed through some JSON like the following:
-```json
-"commands": [
-  {
-    "icon": "...",
-    "name": { "key": "NewTabWithProfileRootCommandName" },
-    "commands": [
-      {
-        "iterateOn": "profiles",
-        "icon": "${profile.icon}",
-        "name": { "key": "NewTabWithProfileCommandName" },
-        "command": { "action": "newTab", "profile": "${profile.name}" }
-      }
-    ]
-  },
-  {
-    "icon": "...",
-    "name": "Connect to ssh...",
-    "commands": [
-      {
-        "icon": "...",
-        "name": "first.com",
-        "command": { "action": "newTab", "commandline": "ssh me@first.com" }
-      },
-      {
-        "icon": "...",
-        "name": "second.com",
-        "command": { "action": "newTab", "commandline": "ssh me@second.com" }
-      }
-    ]
-  }
-  {
-    "icon": "...",
-    "name": { "key": "SplitPaneWithProfileRootCommandName" },
-    "commands": [
-      {
-        "iterateOn": "profiles",
-        "icon": "${profile.icon}",
-        "name": { "key": "SplitPaneWithProfileCommandName" },
-        "commands": [
-          {
-            "icon": "...",
-            "name": { "key": "SplitPaneName" },
-            "command": { "action": "splitPane", "profile": "${profile.name}", "split": "automatic" }
-          },
-          {
-            "icon": "...",
-            "name": { "key": "SplitPaneVerticalName" },
-            "command": { "action": "splitPane", "profile": "${profile.name}", "split": "vertical" }
-          },
-          {
-            "icon": "...",
-            "name": { "key": "SplitPaneHorizontalName" },
-            "command": { "action": "splitPane", "profile": "${profile.name}", "split": "horizontal" }
-          }
-        ]
-      }
-    ]
-  }
-]
-```
-
-This would define three commands, each with a number of nested commands underneath it:
-* For the first command:
-  - It uses the XAML resource `NewTabWithProfileRootCommandName` as it's name.
-  - Activating this command would cause us to remove all the other commands from
-    the command palette, and only show the nested commands.
-  - It contains nested commands, one for each profile.
-    - Each nested command would use the XAML resource
-      `NewTabWithProfileCommandName`, which then would also contain the string
-      `${profile.name}`, to be filled with the profile's name in the command's
-      name.
-    - It would also use the profile's icon as the command icon.
-    - Activating any of the nested commands would dispatch an action to create a
-      new tab with that profile
-* The second command:
-  - It uses the string literal `"Connect to ssh..."` as it's name
-  - It contains two nested commands:
-    - Each nested command has it's own literal name
-    - Activating these commands would cause us to open a new tab with the
-      provided `commandline` instead of the default profile's `commandline`
-* The third command:
-  - It uses the XAML resource `NewTabWithProfileRootCommandName` as it's name.
-  - It contains nested commands, one for each profile.
-    - Each one of these sub-commands each contains 3 subcommands - one that will
-      create a new split pane automatically, one vertically, and one
-      horizontally, each using the given profile.
-
-So, you could imagine the entire tree as follows:
-
-```
-<Command Palette>
-├─ New Tab With Profile...
-│  ├─ Profile 1
-│  ├─ Profile 2
-│  └─ Profile 3
-├─ Connect to ssh...
-│  ├─ first.com
-│  └─ second.com
-└─ New Pane...
-   ├─ Profile 1...
-   |  ├─ Split Automatically
-   |  ├─ Split Vertically
-   |  └─ Split Horizontally
-   ├─ Profile 2...
-   |  ├─ Split Automatically
-   |  ├─ Split Vertically
-   |  └─ Split Horizontally
-   └─ Profile 3...
-      ├─ Split Automatically
-      ├─ Split Vertically
-      └─ Split Horizontally
-```
-
-Note that the palette isn't displayed like a tree - it only ever displays the
-commands from one single level at a time. So at first, only:
-
-* New Tab With Profile...
-* Connect to ssh...
-* New Pane...
-
-are visible. Then, when the user <kbd>enter</kbd>'s on one of these (like "New
-Pane"), the UI will change to display:
-
-* Profile 1...
-* Profile 2...
-* Profile 3...
-
-### Configuring the Action/Commandline Mode prefix
-
-As always, I'm also on board with the "this should be configurable by the user"
-route, so they can change what mode the command palette is in by default, and
-what the prefixes for different modes are, but I'm not sure how we'd define that
-cleanly in the settings.
-
-```json
-{
-  "commandPaletteActionModePrefix": "", // or null, for no prefix
-  "commandPaletteCommandlineModePrefix": ">"
-}
-```
-
-We'd need to have validation on that though, what if both of them were set to
-`null`? One of them would _need_ to be `null`, so if both have a character, do
-we just assume one is the default?

-# Command Palette, Addendum 1 -  Unified keybindings and commands, and synthesized action names
-
-## Abstract
-
-This document is intended to serve as an addition to the [Command Palette Spec].
-While that spec is complete in it's own right, subsequent discussion revealed
-additional ways to improve the functionality and usability of the command
-palette. This document builds largely on the topics already introduced in the
-original spec, so readers should first familiarize themselves with that
-document.
-
-One point of note from the original document was that the original specification
-was entirely too verbose when defining both keybindings and commands for
-actions. Consider, for instance, a user that wants to bind the action "duplicate
-the current pane". In that spec, they need to add both a keybinding and a
-command:
-
-```json
-{
-    "keybindings": [
-        { "keys": [ "ctrl+alt+t" ], "command": { "action": "splitPane", "split":"auto", "splitMode": "duplicate" } },
-    ],
-    "commands": [
-        { "name": "Duplicate Pane", "action": { "action": "splitPane", "split":"auto", "splitMode": "duplicate" }, "icon": null },
-    ]
-}
-```
-
-These two entries are practically the same, except for two key differentiators:
-* the keybinding has a `keys` property, indicating which key chord activates the
-  action.
-* The command has a `name` property, indicating what name to display for the
-  command in the Command Palette.
-
-What if the user didn't have to duplicate this action? What if the user could
-just add this action once, in their `keybindings` or `commands`, and have it
-work both as a keybinding AND a command?
-
-
-## Solution Design
-
-This spec will outline two primary changes to keybindings and commands.
-1. Unify keybindings and commands, so both `keybindings` and `commands` can
-   specify either actions bound to keys, and/or actions bound to entries in the
-   Command Palette.
-2. Propose a mechanism by which actions do not _require_ a `name` to appear in
-   the Command Palette.
-
-These proposals are two atomic units - either could be approved or rejected
-independently of one another. They're presented together here in the same doc
-because together, they present a compelling story.
-
-### Proposal 1: Unify Keybindings and Commands
-
-As noted above, keybindings and commands have nearly the exact same syntax, save
-for a couple properties. To make things easier for the user, I'm proposing
-treating everything in _both_ the `keybindings` _and_ the `commands` arrays as
-**BOTH** a keybinding and a command.
-
-Furthermore, as a change from the previous spec, we'll be using `bindings` from
-here on as the unified `keybindings` and `commands` lists. This is considering
-that we'll currently be using `bindings` for both commands and keybindings, but
-we'll potentially also have mouse & touch bindings in this array in the future.
-We'll "deprecate" the existing `keybindings` property, and begin to exclusively
-use `bindings` as the new property name. For compatibility reasons, we'll
-continue to parse `keybindings` in the same way we parse `bindings`. We'll
-simply layer `bindings` on top of the legacy `keybindings`.
-
-* Anything entry that has a `keys` value will be added to the keybindings.
-  Pressing that keybinding will activate the action defined in `command`.
-* Anything with a `name`<sup>[1]</sup> will be added as an entry (using that
-  name) to the Command Palette's Action Mode.
-
-###### Caveats
-
-* **Nested commands** (commands with other nested commands). If a command has
-  nested commands in the `commands` property, AND a `keys` property, then
-  pressing that keybinding should open the Command Palette directly to that
-  level of nesting of commands.
-* **"Iterable" commands** (with an `iterateOn` property): These are commands
-  that are expanded into one command per profile. These cannot really be bound
-  as keybindings - which action should be bound to the key? They can't all be
-  bound to the same key. If a KeyBinding/Command json blob has a valid
-  `iterateOn` property, then we'll ignore it as a keybinding. This includes any
-  commands that are nested as children of this command - we won't be able to
-  know which of the expanded children will be the one to bind the keys to.
-
-<sup>[1]</sup>: This requirement will be relaxed given **Proposal 2**, below,
-but ignored for the remainder of this section, for illustrative purposes.
-
-#### Example
-
-Consider the following settings:
-
-```json
-"bindings": [
-  { "name": "Duplicate Tab", "command": "duplicateTab", "keys": "ctrl+alt+a" },
-  { "command": "nextTab", "keys": "ctrl+alt+b" },
-  {
-    "icon": "...",
-    "name": { "key": "NewTabWithProfileRootCommandName" },

-          }
-        ]
-      }
-    ]
-  }
-]
-```
-
-This will generate a tree of commands as follows:
-
-```
-<Command Palette>
-├─ Duplicate tab { ctrl+alt+a }
-├─ New Tab With Profile...
-│  ├─ Profile 1
-│  ├─ Profile 2
-│  └─ Profile 3
-├─ Connect to ssh...
-│  ├─ first.com { ctrl+alt+c }
-│  └─ second.com { ctrl+alt+d }
-└─ New Pane... { ctrl+alt+e }
-   ├─ Profile 1...
-   |  ├─ Split Automatically
-   |  ├─ Split Vertically
-   |  └─ Split Horizontally
-   ├─ Profile 2...
-   |  ├─ Split Automatically
-   |  ├─ Split Vertically
-   |  └─ Split Horizontally
-   └─ Profile 3...
-      ├─ Split Automatically
-      ├─ Split Vertically
-      └─ Split Horizontally
-```
-
-Note also the keybindings in the above example:
-* <kbd>ctrl+alt+a</kbd>: This key chord is bound to the "Duplicate tab"
-  (`duplicateTab`) action, which is also bound to the command with the same
-  name.
-* <kbd>ctrl+alt+b</kbd>: This key chord is bound to the `nextTab` action, which
-  doesn't have an associated command.
-* <kbd>ctrl+alt+c</kbd>: This key chord is bound to the "Connect to
-  ssh../first.com" action, which will open a new tab with the `commandline`
-  `"ssh me@first.com"`. When the user presses this keybinding, the action will
-  be executed immediately, without the Command Palette appearing.
-* <kbd>ctrl+alt+d</kbd>: This is the same as the above, but with the "Connect to
-  ssh../second.com" action.
-* <kbd>ctrl+alt+e</kbd>: This key chord is bound to opening the Command Palette
-  to the "New Pane..." command's menu. When the user presses this keybinding,
-  they'll be prompted with this command's sub-commands:
-  ```
-  Profile 1...
-  Profile 2...
-  Profile 3...
-  ```
-* <kbd>ctrl+alt+f</kbd>: This key will _not_ be bound to any action. The parent
-  action is iterable, which means that the `SplitPaneName` command is going to
-  get turned into one command for each and every profile, and therefore cannot
-  be bound to just a single action.
-
-### Proposal 2: Automatically synthesize action names
-
-Previously, all Commands were required to have a `name`. This name was used as
-the text for the action in the Action Mode of the Command Palette. However, this
-is a little tedious for users who already have lots of keys bound. They'll need
-to go through and add names to each of their existing keybindings to ensure that
-the actions appear in the palette. Could we instead synthesize the names for the
-commands ourselves? This  would enable users to automatically get each of their
-existing keybindings to appear in the palette without any extra work.
-
-To support this, the following changes will be made:
-* `ActionAndArgs` will get a `GenerateName()` method defined. This will create a
-  string describing the `ShortcutAction` and it's associated `ActionArgs`.
-  - Not EVERY action _needs_ to define a result for `GenerateName`. Actions that
-    don't _won't_ be automatically added to the Command Palette.
-  - Each of the strings used in `GenerateName` will need to come from our
-    resources, so they can be localized appropriately.
-* When we're parsing commands, if a command doesn't have a `name`, we'll instead
-  attempt to use `GenerateName` to create the unique string for the action
-  associated with this command. If the command does have a `name` set, we'll use
-  that string instead, allowing the user to override the default name.
-  - If a command has it's name set to `null`, then we'll ignore the command
-    entirely, not just use the generated name.
-
-[**Appendix 1**](#appendix-1-name-generation-samples-for-ShortcutActions) below
-shows a complete sample of the strings that will be generated for each of the existing
-`ShortcutActions`, and many of the actions that have been proposed, but not yet
-implemented.
-
-These strings should be human-friendly versions of the actions and their
-associated args. For some of these actions, with very few arguments, the strings
-can be relatively simple. Take for example, `CopyText`:
-
-JSON | Generated String
--- | --
-`{ "action":"copyText" }` | "Copy text"
-`{ "action":"copyText", "singleLine": true }` | "Copy text as a single line"
-`{ "action":"copyText", "singleLine": false, "copyFormatting": false }` | "Copy text without formatting"
-`{ "action":"copyText", "singleLine": true, "copyFormatting": true }` | "Copy text as a single line without formatting"
-
-CopyText is a bit of a simplistic case however, with very few args or
-permutations of argument values. For things like `newTab`, `splitPane`, where
-there are many possible arguments and values, it will be acceptable to simply
-append `", property:value"` strings to the generated names for each of the set
-values.
-
-For example:
-
-JSON | Generated String
--- | --
-`{ "action":"newTab", "profile": "Hello" }` | "Open a new tab, profile:Hello"
-`{ "action":"newTab", "profile": "Hello", "directory":"C:\\", "commandline": "wsl.exe", title": "Foo" }` | "Open a new tab, profile:Hello, directory:C:\\, commandline:wsl.exe, title:Foo"
-
-
-This is being chosen in favor of something that might be more human-friendly,
-like "Open a new tab with profile {profile name} in {directory} with
-{commandline} and a title of {title}". This string would be much harder to
-synthesize, especially considering localization concerns.
-
-#### Remove the resource key notation
-
-Since we'll be using localized names for each of the actions in `GenerateName`,
-we no longer _need_ to provide the `{ "name":{ "key": "SomeResourceKey" } }`
-syntax introduced in the original spec. This functionality was used to allow us
-to define localizable names for the default commands.
-
-However, I think we should keep this functionality, to allow us additional
-flexibility when defining default commands.
-
-### Complete Defaults
-
-Considering both of the above proposals, the default keybindings and commands
-will be defined as follows:
-
-* The current default keybindings will be untouched. These actions will
-  automatically be added to the Command Palette, using their names generated
-  from `GenerateName`.
-  - **TODO: FOR DISCUSSION**: Should we manually set the names for the default
-    "New Tab, profile index: 0" keybindings to `null`? This seems like a not
-    terribly helpful name for the Command Palette, especially considering the
-    iterable commands listed below.
-* We'll add a few new commands:
-  - A nested, iterable command for "Open new tab with
-    profile..."/"Profile:{profile name}"
-  - A nested, iterable command for "Select color scheme..."/"{scheme name}"
-  - A nested, iterable command for "New Pane..."/"Profile:{profile
-    name}..."/["Automatic", "Horizontal", "Vertical"]
-  > 👉 NOTE: These default nested commands can be removed by the user defining
-  > `{ "name": "Open new tab with profile...", "action":null }` (et al) in their
-  > settings.
-  - If we so chose, in the future we can add further commands that we think are
-    helpful to `defaults.json`, without needing to give them keys. For example,
-    we could add
-    ```json
-    { "command": { "action": "copy", "singleLine": true } }
-    ```
-    to `bindings`, to add a "copy text as a single line" command, without
-    necessarily binding it to a keystroke.
-
-
-These changes to the `defaults.json` are represented in json as the following:
-
-```json
-"bindings": [
-  {
-    "icon": null,
-    "name": { "key": "NewTabWithProfileRootCommandName" },
-    "commands": [
-      {

-        "icon": "${profile.icon}",
-        "name": "${profile.name}",
-        "command": { "action": "newTab", "profile": "${profile.name}" }
-      }
-    ]
-  },
-  {
-    "icon": null,
-    "name": { "key": "SelectColorSchemeRootCommandName" },
-    "commands": [
-      {
-        "iterateOn": "schemes",
-        "icon": null,

-      }
-    ]
-  },
-  {
-    "icon": null,
-    "name": { "key": "SplitPaneWithProfileRootCommandName" },
-    "commands": [
-      {
-        "iterateOn": "profiles",
-        "icon": "${profile.icon}",
-        "name": { "key": "SplitPaneWithProfileCommandName" },
-        "commands": [
-          {

-          },
-          {
-            "icon": null,
-            "name": { "key": "SplitPaneVerticalName" },
-            "command": { "action": "splitPane", "profile": "${profile.name}", "split": "vertical" }
-          },
-          {
-            "icon": null,

-            "command": { "action": "splitPane", "profile": "${profile.name}", "split": "horizontal" }
-          }
-        ]
-      }
-    ]
-  }
-]
-```
-
-A complete diagram of what the default Command Palette will look like given the
-default keybindings and these changes is given in [**Appendix
-2**](#appendix-2-complete-default-command-palette).
-
-## Concerns
-
-**DISCUSSION**: "New tab with index {index}". How does this play with
-the new tab dropdown customizations in [#5888]? In recent iterations of that
-spec, we changed the meaning of `{ "action": "newTab", "index": 1 }` to mean
-"open the first entry in the new tab menu". If that's a profile, then we'll open
-a new tab with it. If it's an action, we'll perform that action. If it's a
-nested menu, then we'll open the menu to that entry.
-
-Additionally, how exactly does that play with something like `{ "action":
-"newTab", "index": 1, "commandline": "wsl.exe" }`? This is really a discussion
-for that spec, but is an issue highlighted by this spec. If the first entry is
-anything other than a `profile`, then the `commandline` parameter doesn't really
-mean anything anymore. I'm tempted to revert this particular portion of the new
-tab menu customization spec over this.
-
-We could instead add an `index` to `openNewTabDropdown`, and have that string
-instead be "Open new tab dropdown, index:1". That would help disambiguate the
-two.
-
-Following discussion, it was decided that this was in fact the cleanest
-solution, when accounting for both the needs of the new tab dropdown and the
-command palette. The [#5888] spec has been updated to reflect this.
-
-## Future considerations
-
-* Some of these command names are starting to get _very_ long. Perhaps we need a
-  netting to display Command Palette entries on two lines (or multiple, as
-  necessary).
-* When displaying the entries of a nested command to the user, should we display
-  a small label showing the name of the previous command? My gut says _yes_. In
-  the Proposal 1 example, pressing `ctrl+alt+e` to jump to "Split Pane..."
-  should probably show a small label that displays "Split Pane..." above the
-  list of nested commands.
-* It wouldn't be totally impossible to allow keys to be bound to an iterable
-  command, and then simply have the key work as "open the command palette with
-  only the commands generated by this iterable command". This is left as a
-  future option, as it might require some additional technical plumbing.

-  - "Set the color for this tab..."

-* `RenameTab`

-  - "Rename this tab..."
-    * this command isn't nested, but hitting enter immediately does something

-# Open Settings Keybinding
-
-## Abstract
-
-This spec outlines an expansion to the existing `openSettings` keybinding.
-
-## Inspiration
-
-As a Settings UI becomes more of a reality, the behavior of this keybinding will be expanded on to better interact with the UI. Prior to a Settings UI, there was only one concept of the modifiable user settings: settings.json.
-
-Once the Settings UI is created, we can expect users to want to access the following scenarios:
-- Settings UI: globals page
-- Settings UI: profiles page
-- Settings UI: color schemes page
-- Settings UI: keybindings page
-- settings.json
-- defaults.json
-These are provided as non-comprehensive examples of pages that might be in a future Settings UI. The rest of the doc assumes these are the pages in the Settings UI.
-
-
-## Solution Design
-Originally, #2557 was intended to allow for a keybinding arg to access defaults.json. I imagined a keybinding arg such as "openDefaults: true/false" to accomplish this. However, this is not expandable in the following scenarios:
-- what if we decide to create more settings files in the future? (i.e. themes.json, extensions.json, etc...)
-- when the Settings UI comes in, there is ambiguity as to what `openSettings` does (json? UI? Which page?)
-
-### Proposition 1.1: the minimal `target` arg
-Instead, what if we introduced a new `target` keybinding argument, that could be used as follows:
-| Keybinding Command | Behavior |
-|--|--|
-| `"command": { "action": "openSettings", "target": "settingsFile" }`       | opens "settings.json" in your default text editor |
-| `"command": { "action": "openSettings", "target": "defaultsFile" }`       | opens "defaults.json" in your default text editor |
-| `"command": { "action": "openSettings", "target": "allSettingsFiles" }`   | opens all of settings files in your default text editor |
-| `"command": { "action": "openSettings", "target": "settingsUI" }`         | opens the Settings UI |
-
-This was based on Proposition 1 below, but reduced the overhead of people able to define specific pages to go to.
-
-### Other options we considered were...
-
-#### Proposition 1: the `target` arg
-We considered making target be more specific like this:
-| Keybinding Command | Behavior |
-|--|--|
-| `"command": { "action": "openSettings", "target": "settingsFile" }`   | opens "settings.json" in your default text editor |
-| `"command": { "action": "openSettings", "target": "defaultsFile" }`   | opens "defaults.json" in your default text editor |
-| `"command": { "action": "openSettings", "target": "uiSettings" }`     | opens the Settings UI |
-| `"command": { "action": "openSettings", "target": "uiGlobals" }`      | opens the Settings UI to the Globals page |
-| `"command": { "action": "openSettings", "target": "uiProfiles" }`     | opens the Settings UI to the Profiles page |
-| `"command": { "action": "openSettings", "target": "uiColorSchemes" }` | opens the Settings UI to the Color Schemes page |
-
-If the Settings UI does not have a home page, `uiGlobals` and `uiSettings` will do the same thing.
-
-This provides the user with more flexibility to decide what settings page to open and how to access it.
-
-#### Proposition 2: the `format` and `page` args
-Another approach would be to break up `target` into `format` and `page`.
-
-`format` would be either `json` or `ui`, dictating how you can access the setting.
-`page` would be any of the categories we have for settings: `settings`, `defaults`, `globals`, `profiles`, etc...
-
-This could look like this:
-| Keybinding Command | Behavior |
-|--|--|
-| `"command": { "action": "openSettings", "format": "json", "page": "settings" }`     | opens "settings.json" in your default text editor |
-| `"command": { "action": "openSettings", "format": "json", "page": "defaults" }`     | opens "defaults.json" in your default text editor |
-| `"command": { "action": "openSettings", "format": "ui",   "page": "settings" }`     | opens the Settings UI |
-| `"command": { "action": "openSettings", "format": "ui",   "page": "globals" }`      | opens the Settings UI to the Globals page |
-| `"command": { "action": "openSettings", "format": "ui",   "page": "profiles" }`     | opens the Settings UI to the Profiles page |
-| `"command": { "action": "openSettings", "format": "ui",   "page": "colorSchemes" }` | opens the Settings UI to the Color Schemes page |
-
-The tricky thing for this approach is, what do we do in the following scenario:
-```js
-{ "command": { "action": "openSettings", "format": "json", "page": "colorSchemes" } }
-```
-In situations like this, where the user wants a `json` format, but chooses a `page` that is a part of a larger settings file, I propose we simply open `settings.json` (or whichever file contains the settings for the desired feature).
-
-#### Proposition 3: minimal approach
-What if we don't need to care about the page, and we really just cared about the format: UI vs json? Then, we still need a way to represent opening defaults.json. We could simplify Proposition 2 to be as follows:
-- `format`: `json`, `ui`
-- ~`page`~ `openDefaults`: `true`, `false`
-
-Here, we take away the ability to specifically choose which page the user wants to open, but the result looks much cleaner.
-
-If there are concerns about adding more settings files in the future, `openDefaults` could be renamed to be `target`, and this would still serve as a hybrid of Proposition 1 and 2, with less possible options.
-
-## UI/UX Design
-
-The user has full control over modifying and adding these keybindings.
-
-However, the question arises for what the default experience should be. I propose the following:
-| Keychord | Behavior |
-| <kbd>ctrl+,</kbd> | Open settings.json |
-| <kbd>ctrl+alt+,</kbd> | Open defaults.json |
-
-When the Settings UI gets added in, they will be updated to open their respective pages in the Settings UI.

-# Improved keyboard handling in Conpty
-
-## Abstract
-
-The Windows Console internally uses [`INPUT_RECORD`]s to represent the various
-types of input that a user might send to a client application. This includes
-things like keypresses, mouse events, window resizes, etc.
-
-However, conpty's keyboard input is fundamentally backed by VT sequences, which
-limits the range of keys that a terminal application can actually send relative
-to what the console was capable of. This results in a number of keys that were
-previously representable in the console as `INPUT_RECORD`s, but are impossible
-to send to a client application that's running in conpty mode.
-
-Some of these issues include, but are not limited to:
-
-* Some keybindings used by PSReadLine aren't getting through [#879]
-* Bug Report: Control+Space not sent to terminal emulator. [#2865]
-* Shift+Enter always submits, breaking PSReadline features [#530]
-* Powershell: Ctrl-Alt-? does not work in Windows Terminal [#3079]
-* Bug: ctrl+break is not ctrl+c [#1119]
-* Something wrong with keyboard modifiers processing? [#1694]
-* Numeric input not accepted by choice.exe [#3608]
-* Ctrl+Keys that can't be encoded as VT should still fall through as the unmodified character [#3483]
-* Modifier keys are not properly propagated to application hosted in Windows Terminal [#4334] / [#4446]
-
-This spec covers a mechanism by which we can add support to ConPTY so that a
-terminal application could send `INPUT_RECORD`-like key events to conpty,
-enabling client applications to receive the full range of keys once again.
-Included at the bottom of this document is a collection of [options that were
-investigated](#options-considered) as a part of preparing this document.
-
-## Considerations
-
-When evaluating existing encoding schemes for viability, the following things
-were used to evaluate whether or not a particular encoding would work for our
-needs:
-
-* Would a particular encoding be mixable with other normal VT processing easily?
-  - How would the Terminal know when it should send a \<chosen_encoding> key vs
-    a normally encoded one?
-    - For ex, <kbd>Ctrl+space</kbd> - should we send `NUL` or
-      \<chosen_encoding's version of ctrl+space>
-* If there's a scenario where Windows Terminal might _not_ be connected to a
-  conpty, then how does conpty enable \<chosen_encoding>?
-* Is the goal "Full `INPUT_RECORD` fidelity" or "Make the above scenarios work"?
-  - One could imagine having the Terminal special-case the above keys, and send
-    the xterm modifyOtherKeys sequences just for those scenarios.
-    - This would _not_ work for <kbd>shift</kbd> all by itself.
-  - In my _opinion_, "just making the above work" is a subset of "full
-    INPUT_RECORD", and inevitably we're going to want "full INPUT_RECORD"
-
-The goal we're trying to achieve is communicating `INPUT_RECORD`s from the
-terminal to the client app via conpty. This isn't supposed to be a \*nix
-terminal compatible communication, it's supposed to be fundamentally Win32-like.
-
-Keys that we definitely need to support, that don't have unique VT sequences:
-* <kbd>Ctrl+Space</kbd> ([#879], [#2865])
-* <kbd>Shift+Enter</kbd> ([#530])
-* <kbd>Ctrl+Break</kbd> ([#1119])
-* <kbd>Ctrl+Alt+?</kbd> ([#3079])
-* <kbd>Ctrl</kbd>, <kbd>Alt</kbd>, <kbd>Shift</kbd>,  (without another keydown/up) ([#3608], [#4334], [#4446])
-
-> 👉 NOTE: There are actually 5 types of events that can all be encoded as an
-> `INPUT_RECORD`. This spec primarily focuses on the encoding of
-> `KEY_EVENT_RECORD`s. It is left as a Future Consideration to add support for
-> the other types of `INPUT_RECORD` as other sequences, which could be done
-> trivially similarly to the following proposal.
-
-## Solution Design
-
-### Inspiration
-
-The design we've settled upon is one that's highly inspired by a few precedents:
-* `Application Cursor Keys (DECCKM)` is a long-supported VT sequence which a
-  client application can use to request a different input format from the
-  Terminal. This is the DECSET sequence `^[[?1h`/`^[[?1l` (for enable/disable,
-  respectively). This changes the sequences sent by keys like the Arrow keys
-  from a sequence like `^[[A` to `^[OA` instead.
-* The `kitty` terminal emulator uses a similar DECSET sequence for enabling
-  their own input format, which they call ["full mode"]. Similar to DECCKM, this
-  changes the format of the sequences that the terminal should send for keyboard
-  input. Their "full mode" contains much more information when keys are pressed
-  or released (though, less than a full `INPUT_RECORD` worth of data). Instead
-  of input being sent to the client as a CSI or SS3 sequence, this `kitty` mode
-  uses "Application Program-Command" (or "APC") sequences , prefixed with `^[_`.
-* [iTerm2](https://www.iterm2.com/documentation-escape-codes.html) has a region
-  of OSC's that they've carved for themselves all starting with the same initial
-  parameter, `1337`. They then have a number of commands that all use the second
-  parameter to indicate what command specific to iTerm2 they're actually
-  implementing.
-
-### Requesting `win32-input-mode`
-
-An application can request `win32-input-mode` with the following private mode sequence:
-
-```
-  ^[ [ ? 9001 h/l
-              l: Disable win32-input-mode
-              h: Enable win32-input-mode
-```
-
-Private mode `9001` seems unused according to the [xterm
-documentation](https://invisible-island.net/xterm/ctlseqs/ctlseqs.html). This is
-stylistically similar to how `DECKPM`, `DECCKM`, and `kitty`'s ["full mode"] are
-enabled.
-
-> 👉 NOTE: an earlier draft of this spec used an OSC sequence for enabling these
-> sequences. This was abandoned in favor of the more stylistically consistent
-> private mode params proposed above. Additionally, if implemented as a private
-> mode, then a client app could query if this setting was set with `DECRQM`
-
-When a terminal receives a `^[[?9001h` sequence, they should switch into
-`win32-input-mode`. In `win32-input-mode`, the terminal will send keyboard input
-to the connected client application in the following format:
-
-### `win32-input-mode` sequences
-
-The `KEY_EVENT_RECORD` portion of an input record (the part that's important for
-us to encode in this feature) is defined as the following:
-
-```c++
-typedef struct _KEY_EVENT_RECORD {
-  BOOL  bKeyDown;
-  WORD  wRepeatCount;
-  WORD  wVirtualKeyCode;
-  WORD  wVirtualScanCode;
-  union {
-    WCHAR UnicodeChar;
-    CHAR  AsciiChar;
-  } uChar;
-  DWORD dwControlKeyState;
-} KEY_EVENT_RECORD;
-```
-
-To encode all of this information, I propose the following sequence. This is a
-CSI sequence with a final terminator character of `_`. This character appears to
-only be used as a terminator for the [SCO input
-sequence](https://vt100.net/docs/vt510-rm/chapter6.html) for
-<kbd>Ctrl+Shift+F10</kbd>. This conflict isn't a real concern for us
-compatibility wise. For more details, see [SCO
-Compatibility](#SCO-compatibility) below.
-
-```
-  ^[ [ Vk ; Sc ; Uc ; Kd ; Cs ; Rc _
-
-       Vk: the value of wVirtualKeyCode - any number. If omitted, defaults to '0'.
-
-       Sc: the value of wVirtualScanCode - any number. If omitted, defaults to '0'.
-
-       Uc: the decimal value of UnicodeChar - for example, NUL is "0", LF is
-           "10", the character 'A' is "65". If omitted, defaults to '0'.
-
-       Kd: the value of bKeyDown - either a '0' or '1'. If omitted, defaults to '0'.
-
-       Cs: the value of dwControlKeyState - any number. If omitted, defaults to '0'.
-
-       Rc: the value of wRepeatCount - any number. If omitted, defaults to '1'.
-
-```
-
-> 👉 NOTE: an earlier draft of this spec used an APC sequence for encoding the
-> input sequences. This was changed to a CSI for stylistic reasons. There's not
-> a great body of reference anywhere that lists APC sequences in use, so there's
-> no way to know if the sequence would collide with another terminal emulator's
-> usage. Furthermore, using an APC seems to give a distinct impression that
-> this is some "Windows Terminal" specific sequence, which is not intended. This
-> is a Windows-specific sequence, but one that any Terminal/application could
-> use.
-
-In this way, a terminal can communicate input to a connected client application
-as `INPUT_RECORD`s, without any loss of fidelity.
-
-#### Example
-
-When the user presses <kbd>Ctrl+F1</kbd> in the console, the console actually
-send 4 input records to the client application:
-* A <kbd>Ctrl</kbd> down event
-* A <kbd>F1</kbd> down event
-* A <kbd>F1</kbd> up event
-* A <kbd>Ctrl</kbd> up event
-
-Encoded in `win32-input-mode`, this would look like the following:
-```
-^[[17;29;0;1;8;1_
-^[[112;59;0;1;8;1_
-^[[112;59;0;0;8;1_
-^[[17;29;0;0;0;1_
-
-Down: 1 Repeat: 1 KeyCode: 0x11 ScanCode: 0x1d Char: \0 (0x0) KeyState: 0x28
-Down: 1 Repeat: 1 KeyCode: 0x70 ScanCode: 0x3b Char: \0 (0x0) KeyState: 0x28
-Down: 0 Repeat: 1 KeyCode: 0x70 ScanCode: 0x3b Char: \0 (0x0) KeyState: 0x28
-Down: 0 Repeat: 1 KeyCode: 0x11 ScanCode: 0x1d Char: \0 (0x0) KeyState: 0x20
-```
-
-Similarly, for a keypress like <kbd>Ctrl+Alt+A</kbd>, which is 6 key events:
-```
-^[[17;29;0;1;8;1_
-^[[18;56;0;1;10;1_
-^[[65;30;0;1;10;1_
-^[[65;30;0;0;10;1_
-^[[18;56;0;0;8;1_
-^[[17;29;0;0;0;1_
-
-Down: 1 Repeat: 1 KeyCode: 0x11 ScanCode: 0x1d Char: \0 (0x0) KeyState: 0x28
-Down: 1 Repeat: 1 KeyCode: 0x12 ScanCode: 0x38 Char: \0 (0x0) KeyState: 0x2a
-Down: 1 Repeat: 1 KeyCode: 0x41 ScanCode: 0x1e Char: \0 (0x0) KeyState: 0x2a
-Down: 0 Repeat: 1 KeyCode: 0x41 ScanCode: 0x1e Char: \0 (0x0) KeyState: 0x2a
-Down: 0 Repeat: 1 KeyCode: 0x12 ScanCode: 0x38 Char: \0 (0x0) KeyState: 0x28
-Down: 0 Repeat: 1 KeyCode: 0x11 ScanCode: 0x1d Char: \0 (0x0) KeyState: 0x20
-```
-
-Or, for something simple like <kbd>A</kbd> (which is 4 key events):
-```
-^[[16;42;0;1;16;1_
-^[[65;30;65;1;16;1_
-^[[16;42;0;0;0;1_
-^[[65;30;97;0;0;1_
-
-Down: 1 Repeat: 1 KeyCode: 0x10 ScanCode: 0x2a Char: \0 (0x0) KeyState: 0x30
-Down: 1 Repeat: 1 KeyCode: 0x41 ScanCode: 0x1e Char: A  (0x41) KeyState: 0x30
-Down: 0 Repeat: 1 KeyCode: 0x10 ScanCode: 0x2a Char: \0 (0x0) KeyState: 0x20
-Down: 0 Repeat: 1 KeyCode: 0x41 ScanCode: 0x1e Char: a  (0x61) KeyState: 0x20
-```
-
-> 👉 NOTE: In all the above examples, I had my NumLock key off. If I had the
-> NumLock key instead pressed, all the KeyState parameters would have bits 0x20
-> set. To get these keys with a NumLock, add 32 to the value.
-
-These parameters are ordered based on how likely they are to be used. Most of
-the time, the repeat count is not needed (it's almost always `1`), so it can be
-left off when not required. Similarly, the control key state is probably going
-to be 0 a lot of the time too, so that is second last. Even keydown will be 0 at
-least half the time, so that can be omitted some of the time.
-
-Furthermore, considering omitted values in CSI parameters default to the values
-specified above, the above sequences could each be shortened to the following.
-
-* <kbd>Ctrl+F1</kbd>
-```
-^[[17;29;;1;8_
-^[[112;59;;1;8_
-^[[112;59;;;8_
-^[[17;29_
-```
-
-* <kbd>Ctrl+Alt+A</kbd>
-```
-^[[17;29;;1;8_
-^[[18;56;;1;10_
-^[[65;30;;1;10_
-^[[65;30;;;10_
-^[[18;56;;;8_
-^[[17;29;;_
-```
-
-* <kbd>A</kbd> (which is <kbd>shift+a</kbd>)
-```
-^[[16;42;;1;16_
-^[[65;30;65;1;16_
-^[[16;42_
-^[[65;30;97_
-```
-
-* Or even easier, just <kbd>a</kbd>
-```
-^[[65;30;97;1_
-^[[65;30;97_
-```
-
-### Scenarios
-
-#### User is typing into WSL from the Windows Terminal
-
-`WT -> conpty[1] -> wsl`
-
-* Conpty[1] will ask for `win32-input-mode` from the Windows Terminal when
-  conpty[1] first boots up. Conpty will _always_ ask for win32-input-mode -
-  Terminals that _don't_ support this mode will ignore this sequence on startup.
-* When the user types keys in Windows Terminal, WT will translate them into
-  win32 sequences and send them to conpty[1]
-* Conpty[1] will translate those win32 sequences into `INPUT_RECORD`s.
-  - When those `INPUT_RECORD`s are written to the input buffer, they'll be
-    converted into VT sequences corresponding to whatever input mode the linux
-    app is in.
-* When WSL reads the input, it'll read (using `ReadConsoleInput`) a stream of
-  `INPUT_RECORD`s that contain only character information, which it will then
-  pass to the linux application.
-  - This is how `wsl.exe` behaves today, before this change.
-
-#### User is typing into `cmd.exe` running in WSL interop
-
-`WT -> conpty[1] -> wsl -> conpty[2] -> cmd.exe`
-
-(presuming you start from the previous scenario, and launch `cmd.exe` inside wsl)
-
-* Conpty[2] will ask for `win32-input-mode` from conpty[1] when conpty[2] first
-  boots up.
-    - As conpty[1] is just a conhost that knows how to handle
-      `win32-input-mode`, it will switch its own VT input handling into
-      `win32-input-mode`
-* When the user types keys in Windows Terminal, WT will translate them into
-  win32 sequences and send them to conpty[1]
-* Conpty[1] will translate those win32 sequences into `INPUT_RECORD`s. When
-  conpty[1] writes these to its buffer, it will translate the `INPUT_RECORD`s
-  into VT sequences for the `win32-input-mode`. This is because it believes the
-  client (in this case, the conpty[2] running attached to `wsl`) wants
-  `win32-input-mode`.
-* When WSL reads the input, it'll read (using `ReadConsoleInput`) a stream of
-  `INPUT_RECORD`s that contain only character information, which it will then
-  use to pass a stream of characters to conpty[2].
-* Conpty[2] will get those sequences, and will translate those win32 sequences
-  into `INPUT_RECORD`s
-* When `cmd.exe` reads the input, they'll receive the full `INPUT_RECORD`s
-  they're expecting
-
-
-## UI/UX Design
-
-This is not a user-facing feature.
-
-## Capabilities
-
-### Accessibility
-
-_(no change expected)_
-
-### Security
-
-_(no change expected)_
-
-### Reliability
-
-_(no change expected)_
-
-### Compatibility
-
-This isn't expected to break any existing scenarios. The information that we're
-passing to conpty from the Terminal should strictly have _more_ information in
-them than they used to. Conhost was already capable of translating
-`INPUT_RECORD`s back into VT sequences, so this should work the same as before.
-
-There's some hypothetical future where the Terminal isn't connected to conpty.
-In that future, the Terminal will still be able to work correctly, even with
-this ConPTY change. The Terminal will only switch into sending
-`win32-input-mode` sequences when _conpty asks for them_. Otherwise, the
-Terminal will still behave like a normal terminal emulator.
-
-#### Terminals that don't support `?9001h`
-
-Traditionally, whenever a terminal emulator doesn't understand a particular VT
-sequence, they simply ignore the unknown sequence. This assumption is being
-relied upon heavily, as ConPTY will _always_ emit a `^[[?9001h` on
-initialization, to request `win32-input-mode`.
-
-#### SCO Compatibility
-
-As mentioned above, the `_` character is used as a terminator for the [SCO input
-sequence](https://vt100.net/docs/vt510-rm/chapter6.html) for
-<kbd>Ctrl+Shift+F10</kbd>. This conflict would be a problem if a hypothetical
-terminal was connected to conpty that sent input to conpty in SCO format.
-However, if that terminal was only sending input to conpty in SCO mode, it would
-have much worse problems than just <kbd>Ctrl+Shift+F10</kbd> not working. If we
-did want to support SCO mode in the future, I'd even go so far as to say we
-could maybe treat a `win32-input-mode` sequence with no params as
-<kbd>Ctrl+Shift+F10</kbd>, considering that `KEY_EVENT_RECORD{0}` isn't really
-valid anyways.
-
-#### Remoting `INPUT_RECORD`s
-
-A potential area of concern is the fact that VT sequences are often used to
-remote input from one machine to another. For example, a terminal might be
-running on machine A, and the conpty at the end of the pipe (which is running
-the client application) might be running on another machine B.
-
-If these two machines have different keyboard layouts, then it's possible that
-the `INPUT_RECORD`s synthesized by the terminal on machine A won't really be
-valid on machine B. It's possible that machine B has a different mapping of scan
-codes \<-> characters. A client that's running on machine B that uses win32 APIs
-to try and infer the vkey, scancode, or character from the other information in
-the `INPUT_RECORD` might end up synthesizing the wrong values.
-
-At the time of writing, we're not really sure what a good solution to this
-problem would be. Client applications that use `win32-input-mode` should be
-aware of this, and be written with the understanding that these values are
-coming from the terminal's machine, which might not necessarily be the local
-machine.
-
-### Performance, Power, and Efficiency
-
-_(no change expected)_
-
-## Potential Issues
-
-_(no change expected)_
-
-## Future considerations
-
-* We could also hypothetically use this same mechanism to send Win32-like mouse
-  events to conpty, since similar to VT keyboard events, VT mouse events don't
-  have the same fidelity that Win32 mouse events do.
-  - We could enable this with a different terminating character, to identify
-    which type of `INPUT_RECORD` event we're encoding.
-* Client applications that want to be able to read full Win32 keyboard input
-  from `conhost` _using VT_ will also be able to use `^[[?9001h` to do this. If
-  they emit `^[[?9001h`, then conhost will switch itself into
-  `win32-input-mode`, and the client will read `win32-input-mode` encoded
-  sequences as input. This could enable other cross-platform applications to
-  also use win32-like input in the future.
-
-## Options Considered
-
-_disclaimer: these notes are verbatim from my research notes in [#4999]_.
-
-### Create our own format for `INPUT_RECORD`s
-
-* If we wanted to do this, then we'd probably want to have the Terminal only
-  send input as this format, and not use the existing translator to synthesize
-  VT sequences
-    - Consider sending a ctrl down, '^A', ctrl up. We wouldn't want to send this
-      as three sequences, because conpty will take the '^A' and synthesize
-      _another_ ctrl down, ctrl up pair.
-* With conpty passthrough mode, we'd still need the `InputStateMachineEngine`
-  to convert these sequences into INPUT_RECORDs to translate back to VT
-* Wouldn't really expect client apps to ever _need_ this format, but it could
-  always be possible for them to need it in the future.
-
-#### Pros:
-* Definitely gets us all the information that we need.
-* Can handle solo modifiers
-* Can handle keydown and keyup separately
-* We can make the sequence however we want to parse it.
-
-#### Cons:
-* No reference implementation, so we'd be flying blind
-* We'd be defining our own VT sequences for these, which we've never done
-  before. This was _inevitable_, however, this is still the first time we'd be
-  doing this.
-* By having the Terminal send all input as _this protocol_, VT Input passthrough
-  to apps that want VT input won't work anymore for the Terminal. That's _okay_
-
-### kitty extension
-[Reference](https://sw.kovidgoyal.net/kitty/protocol-extensions.html#keyboard-handling)
-
-#### Pros:
-* Not terribly difficult to decode
-* Unique from anything else we'd be processing, as it's an APC sequence
-  (`\x1b_`)
-* From their docs:
-  > All printable key presses without modifier keys are sent
-  just as in the normal mode. ... For non printable keys and key combinations
-  including one or more modifiers, an escape sequence encoding the key event is
-  sent
-   - I think I like this. ASCII and other keyboard layout chars (things that would
-     hit `SendChar`) would still just come through as the normal char.
-
-#### Cons:
-* Their encoding table is _odd_. [Look at
-  this](https://sw.kovidgoyal.net/kitty/key-encoding.html). What order is that
-  in? Obviously the first column is sorted alphabetically, but the mapping of
-  key->char is in a certainly hard to decipher order.
-* I can't get it working locally, so hard to test 😐
-* They do declare the `fullkbd` terminfo capability to identify that they
-  support this mode, but I'm not sure anyone else uses it.
-  - I'm also not sure that any _client_ apps are reading this currently.
-* This isn't designed to be full `KEY_EVENT`s - where would we put the scancode
-  (for apps that think that's important)?
-  - We'd have to extend this protocol _anyways_
-
-### `xterm` "Set key modifier options"
-Notably looking at
-[`modifyOtherKeys`](https://invisible-island.net/xterm/manpage/xterm.html#VT100-Widget-Resources:modifyOtherKeys).
-
-#### Pros:
-* `xterm` implements this so there's a reference implementation

-# Tab Tearoff/Merge & Default App IPC
-
-## Abstract
-
-This spec describes the sort of interprocess communications that will be required to support features like tab tearoff and merge. It goes through some of the considerations that became apparent when I tried to prototype passing connections between `conhost` and `wt`.
-
-## Inspiration
-
-Two main drivers:
-1. We want the ability to tear off a tab from one Windows Terminal instance and send it to another Windows Terminal instance
-2. We want the ability for a launch of a command-line application to trigger a hosting environment that isn't the stock in-box `conhost.exe`.
-
-Both of these concerns will require there to exist some sort of interprocess communication manager that can send/receive the system handles representing connections between client applications and the hosting environment.
-
-I spent some time during the Microsoft Hackathon in July 2019 investigating these avenues with a branch I pushed and linked at the bottom. The work resulted in me finding more questions than answers and ultimately deciding that a Hackathon is good enough for exploration of the mechanisms and ideas behind this, but not a good time for a full implementation.
-
-## Solution Design
-
-### Common Pieces
-
-There are several common pieces needed for both the tab tear-off scenario and the default application scenario.
-
-#### Manager
-
-We need some sort of server/manager code that sits there waiting for connections from `wt.exe` processes and potentially `conhost.exe` processes such that it can broker a connection between the processes. It either needs to run in its own process or it needs to run in one of the existing `wt.exe`s that is chosen as the primary manager at the time. It should create communication channels and a global mutex at the time of creation.
-
-All other `wt.exe` processes starting after the primary should detect the existence of the server manager process and wait on the mutex handle. When the primary disappears, the OS scheduler should choose one of the others to wake up first on the mutex. It can take the lock and then set up the primary management channel. 
-
-Alternatively, if the manager process is completely isolated and we expect all `wt.exe`s to have to remain connected at all times, we can make it such that when the connections are broken between the individual processes and the manager that they all shut down. I would prefer that it is resilient (the previous option) over this one, but browsers must have a good reason for preferring this way.
-
-I attempted one particular way in a prototype of communicating between processes by setting up a Multithreaded Pipe Server using a Message-type configuration. This is visible in the branch I linked at the bottom. However, ultimately I think we would want to formalize around something more structured, tested, and inherently secured like a COM server interface.
-
-#### Connection details
-
-There are several parameters to a connection and several different modes. In short, they summarize to the ability to pass kernel handles between two processes and/or the ability to pass arbitrary length structured information about paths and settings. Both tab tear off and default application will likely need both functionalities.
-
-##### Fresh Start
-For an application that is being freshly started, the information required to begin the session is one of three things:
-1. A server (and maybe reference) handle that describes the driver connection between the console server and the command-line client process. A `conhost.exe` can wrap this and turn it into a PTY. This may also contain LNK file (shortcut file) preferences for the running session.
-1. A command-line string and working directory that describes which command-line client process we want to start. A `conhost.exe` can start this up and create the server and reference handles along the way and then turn it into a PTY.
-1. A PTY session with its read, write, and signal handles.
-
-When transiting a connection, we need to be aware of all three of these modes and relay them to the destination `wt.exe`.
-
-For system handles, we can use the manager to broker a request to the destination process to find its `PID` and tell the source process. We can then use the `PID` with the `OpenProcess` method and the `PROCESS_DUP_HANDLE` right to get a handle to `DuplicateHandle` any of the above handle types into the destination process. The act of opening and duplicating the handles already requires the OS to check our access tokens and rights to interfere with another process, so that should automatically handle some level of the security checking for us.
-
-For command-line string and working directory, we can pass all of this information along to the destination `wt.exe` and let it attempt to start a new ConPTY normally as if someone had chosen to start an option from the dropdown menu. A minor trick here is that we may need to attempt to match the command-line string with one of the user profiles to line up the icon and user-preferences for how the session should launch.
-
-Lastly, for things started from an LNK, a user might expect that a window launched inside `wt.exe` from an old shortcut that they had would still apply even if that shortcut's properties technically apply to `conhost.exe` preferences and not to `wt.exe` preferences. The behavior here would likely to be to transit the LNK file information along to the `wt.exe` process by the same mechanism as a command-line string or working directory and let `wt.exe` use the shortcut parsing shared libraries to extract this information and migrate it into a `Settings` preference. Whether we would store that `Settings` preference or not for future use in the drop down might be an option or a prompt.
-
-##### Already Running
-For an application that is already running, we will need to send several pieces of information to successfully migrate to a new tab location:
-1. The ConPTY handles for read, write, and signal
-1. The scroll-back history that is stored inside `wt.exe` but isn't actually a part of what the underlying PTY-mode `conhost.exe` re-renders at any given time
-1. The user preferences and session information related to `Settings`.
-
-We would send all of this over to the destination by whatever IPC mechanism and then let it stand up a new tab with all of the same parameters as the tab on the other end.
-
-**ALTERNATIVELY**
-
-If we move everything to an isolated process model where the individual tabs/panes have a process and their UI is hosted in another frame/shell process and then there's a manager process, we will presumably already have to architect a solution that allows the UIs to be remoted onto other interfaces (Component UI?). If this is true, then all we need to relay for an active session is the information required to redirect the drawing/input targets for a given tab/pane to a different shell. This may ultimately be easier and more reliable than moving and rebuilding all the pieces of what fundamentally makes a session to the other side.
-
-### Separate Pieces
-
-#### For Tab Tear-off
-
-We add a handler to the on-drag for the tab bar. We also likely need to implement a drag and drop handler. Drag and drop handlers use OLE (COM) so this might be another reason why we should implement the entire manager as COM. Note, I have never used this before so this is a theoretical low-knowledge design that would have to be explored...
-
-Presumably the tab control from WinUI will update to support reordering the tabs through its own drag/drop. But we would likely want to create some sort of drag source with the session GUID when a drag operation starts.
-
-Then we can let the OS handle the drop operation with the session GUID information. If the drop handler drops onto another wt.exe, it can use the session GUID in the drop payload in order to convey connection information between the processes. If it drops somewhere else, presumably we can be made aware of that in the source of the drag/drop operation and instead spawn a new `wt.exe` with arguments that specify that it should start up doing the "drop" portion of the operation to the session GUID with the manager instead of launching the default tab.
-
-#### For Default Application
-
-For default application launches, `conhost.exe` will have to attempt to transfer the incoming connection to the registered terminal handler instead of launching its own UI window.
-
-If the registered handler fails to start the connection, there is no registered handler, or any part of this mechanism fails. The `conhost.exe` needs to fall back to doing whatever it would have done prior to this development (launching a window if necessary, being hidden, etc.)
-
-##### Interactive vs. Not
-
-We would have to be able to detect the difference between an interactive and non-interactive mode here. 
-- Interactive is defined as the end-user is attempting to launch a command-line application with a visible window to see the output and enter input.
-- Non-interactive is defined as tools, utilities, and services attempting to launch a command-line application with no visible window (and possibly some redirected handles).
-
-We do not want to capture non-interactive sessions as compilers, scripts, and utilities run command-line tools all the time. These should not trigger the overhead of being transitioned into the terminal as they will not need output or display.
-
-Additionally, we may need to identify ConPTYs being started and ensure that they don't accidentally attempt to hand off in an infinite loop.
-
-The biggest trick here is that we don't know whether it is going to be interactive or not until we begin to accept the connection from the server handle. We have two choices here:
-
-##### Inbox conhost handles it
-The inbox `conhost.exe` can just accept the connection from the server handle, assure itself that a `wt.exe` could take over the UI hosting of the session, and then switch itself into `ConPTY` mode and give those handles over to `wt.exe` and remain invisible in the background in PTY mode (much the same as if `wt.exe` had started the connection itself).
-
-The upside here is that most of the startup connection flow happens normally, the `conhost.exe` that was given the server handle is the one that will continue to service it for the lifetime of the command-line application session. I can then discard any concerns about how the driver reacts and how the applications grovel for the relationship between processes as it will be normal.
-
-The downside here is that launching command-line applications from shortcuts, the shell, or the run box (as is what triggers the default application scenario) will be using an old version of the PTY. It is possible and even probable that we will make improvements to the PTY that we would want to leverage if they're on the system already inside the app package. However, if we try to transit the server connection to the PTY in the package, we will have to deal with:
-1. Potentially leaving the original conhost.exe open until the other one exits in case someone is waiting on the process
-1. Coming up with some sort of dance to have the delegated PTY conhost inside the package determine the interactivity on starting the connection **OR** having the outside conhost start the connection and passing the connection off part way through if it's interactive **OR** something of that ilk.
-
-##### Conhost in the Terminal package handles it
-We could just send the server connection from the `conhost.exe` in System32 into the one inside the package and let it deal with it. We can connect to the broker and pass along the server handle and let `wt.exe` create a `conhost.exe` in PTY mode with that specific server handle.
-
-The upsides/downsides here are exactly opposite of those above, so I won't restate.
-
-##### Making default app work on current and downlevel OS
-There's a few areas to study here.
-
-1. Replacing conhost.exe in system32 at install time
-- The OS (via the code for `ConsoleInitialize` inside `kernelbase.dll`) will launch `C:\windows\system32\conhost.exe` to start a default application session with the server handle. We can technically replace this binary in `system32` with an `OpenConsole.exe` named `conhost.exe` to make newer code run on older OS (presuming that we have the CRTs installed, build against the in-OS-CRT, and otherwise have conditional feature detection properly performed for all APIs/references not accessible downlevel). This is how we test/develop locally inside Windows without a full nightly build, so we know it works to some degree. Replacing a binary in `system32` is a bit of a problem, though, because the OS actively works to defend against this through ACLs (Windows File Protection which detected and restored changes here is gone, I believe). Additionally, it works for us because we're using internal builds and signing our binaries with test certificates for which our machines have the root certificate installed. Not going to cut it outside. We probably also can't sign it officially with the app signing mechanism and have it work because I'm not sure the root certificates for app signing will be trusted the same way as the certificates for OS signing. Also, we can't build outside of Windows against the in-box CRT. So we'd have to have the MSVCRT redist, which is also gross.
-
-2. Updating kernelbase.dll to look up the launch preference and/or to launch a console host via a protocol handler
-- To make this work anywhere but the most recent OS build, we'd have to service downlevel. Given `kernelbase.dll` is fundamental to literally everything, there's virtually no chance that we would be allowed to service it backwards in time for the sake of adding a feature. It's too risky by any stretch of the imagination. It's even risky to change `kernelbase.dll` for an upcoming release edition given how fundamental it is. End of thought experiment.
-
-3. Updating conhost.exe to look up the launch preference and/or to launch another console host via a protocol handler
-- This would allow the `C:\windows\system32\conhost.exe` to effectively delegate the session to another `conhost.exe` that is hopefully newer than the inbox one. Given that the driver protocol in the box doesn't change and hasn't changed and we don't intend to change it, the forward/backward compatibility story is great here. Additionally, if for whatever reason the delegated `conhost.exe` fails to launch, we can just fall back and launch the old one like we would have prior to the change. It is significantly more likely, but still challenging, to argue for servicing `conhost.exe` back several versions in Windows to make this light up better for all folks. It might be especially more possible if it is a very targeted code snippet that can drop in to all the old versions of the `conhost.exe` code. We would still have the argument about spending resources developing for OS versions that are supposed to be dropped in favor of latest, but it's still a lesser argument than upending all of `kernelbase.dll`.
-- A protocol handler is also well understood and relatively well handled/tested in Windows. Old apps can handle protocols. New apps can handle protocols. Protocol handlers can take arguments. We don't have to lean on any other team to get them to help change the way the rest of the OS  works. 
-
-#### Communicating the launch
-For the parameters passing, I see a few options:
-1. `conhost.exe` can look up the package registration for `wt.exe` and call an entrypoint with arguments. This could be adapted to instead look up which package is registered as the default one instead of `wt.exe` for third party hosts. We would have to build provisions into the OS to select this, or use some sort of publically documented registry key mechanism. Somewhat gross.
-1. `conhost.exe` can call the execution alias with parameters. WSL distro launchers use this.
-1. We can define a protocol handler for these sorts of connections and let `wt.exe` register for it. Protocol handlers are already well supported and understood both by classic applications and by packaged/modern applications on Windows. They must have provisions to communicate at least some semblance of argument data as well. This is the route I'd probably prefer. `ms-term://incoming/<session-id>` or something like that. The receiving `wt.exe` can contact the manager process (or set one up if it is the first) and negotiate receiving the session that was specified into a new tab.
-
-## UI/UX Design
-
-### For Tab Tear-off
-
-#### Ideal World
-The UX would be just as one might expect from a browser application.
-
-- Mouse down and drag on a tab should provide some visual indication that it is being dragged.
-- Dragging left/right should provide a visual indicator of the tabs reordering on the bar and otherwise not involve the IPC manager service.
-- Dragging up/down to break free from the tab bar should launch a new instance of `wt.exe` passing in the state of the dragging tab as the initial launch point (ignoring other default launch aspects). The drag/mouse-down would be passed to that new instance which would chase the mouse.
-- Continuing to drag the loose tab onto the tab bar of another running instance of `wt.exe` would merge the tab with that copy of the application. The interim new/loose frame instance of `wt.exe` would close when it transferred out the last tab to the drop location.
-
-#### Simplified V1
-To simplify this for a first iteration, we could just make it so the transfer does not happen live.
-- Mouse down and drag on a tab should provide a visual indication that it is being dragged by changing the cursor (or something of that ilk)
-- Nothing would actually happen in terms of transitioning the tab until it is released
-- If released onto the same `wt.exe` instance in a different spot on the tab bar, we reorder the tabs in the tab control
-- If released onto a different `wt.exe` instance, we relay the communications channel and details through the IPC manager to the other instance. It opens the tab on the destination instance; we close the tab on the source instance.
-- If released onto anything that isn't a `wt.exe` instance, we create a new `wt.exe` instance and send in the connection as the default startup parameter.
-
-#### Component UI
-It is also theoretically possible that if we could find a Component UI style solution (where the tab/panes live in their own process and just remote the UI/input into the shell) that it would be easy and even trivial to change out which shell/frame host is holding that element at any given time. 
-
-### For Default Application
-The UX would make it look exactly like the user had started `wt.exe` from a shortcut or launch tile, but would launch the first tab differently than the defaults.
-
-#### No WT already started
-If no `wt.exe` is already started, the `conhost.exe` triggered by the system to host the client application would find the installed `wt.exe` package and launch it with parameters to use as its first connection (in lieu of launching the default tab). `conhost.exe` wouldn't show a window, it would drop into ConPTY mode and only the new `wt.exe` and its tab would be visible.
-
-#### WT already started
-If a `wt.exe` is already started, `conhost.exe` would find the running instance and just add a new tab at the end of the tab bar by the same mechanism.
-
-#### Multiple WTs already started
-If multiple `wt.exe`s are already started, `conhost.exe` would have to find the foreground one, the active one, or the primary/manager one and send the tab there. I'm not sure how other tabbing things to do this. We could research/study.
-
-## Capabilities
-
-### Accessibility
-
-I don't believe it changes anything for accessibility. The only concern I'd have to call out is the knowledge I have that the UIA framework makes its connections and some of its logic/reasoning based on PIDs, HWNDs, and the hierarchy thereof. Playing with these might impact the ability of screen reading applications to get the UIA tree when tabs have been shuffled around.
-
-### Security
-
-This particular feature will have to go through a security review/audit. It is unclear what level of control we will need over the IPC communication channels. A few things come to mind:
-1. We need to ensure that the mutexes/pipes/communications are restricted inside of one particular session to one particular user. If another user is also running WT in their session, it should involve a completely different manager process and system objects.
-1. We MAY have to enforce a scenario where we inhibit cross-integrity-level connections from being passed around. Generally speaking, processes at a higher integrity level have the authority to perform actions on those with a lower integrity level. This means that an elevated `wt.exe` could theoretically send a tab to a standard level `wt.exe`. We may be required to inhibit/prohibit this. We may also need to have one manager per integrity level. 
-1. I'm not sure what sorts of ACL/DACL/SACLs we would need to apply to all the kernel objects involved.
-1. My initial prototype here used message-passing type pipes with a custom rolled protocol. If I make my own protocol, it needs to be fuzzed. And I'm probably missing something. Many/most of these concerns for security are probably eliminated if we use a well-known mechanism for this sort of IPC. My thoughts go to a COM server. More complicated to implement than message pipes, but probably brings a lot of security benefits and eliminates the need to fuzz the protocol (probably).
-
-### Reliability
-
-In the simple implementation, it will decrease reliability. We'll be shuffling connections back and forth between application instances. By default, that's more risky than leaving things alone. The only reason it is worth it is the user experience.
-
-We might be able to mitigate some of the reliability concerns here or even improve reliability by going a step further with the process/containerization model like browsers do and standing up each individual tab as its own process host.
-
-```
-wt.exe - Manager Mode 
-|- wt.exe - Frame Host Mode 
-|   |- wt.exe - Tab Host Mode
-|   |  |- conhost.exe - ConPTY mode
-|   |     |- pwsh.exe - Client application 
-|   |- wt.exe - Tab Host Mode
-|      |- conhost.exe - ConPTY mode
-|         |- cmd.exe - Client application 
-|- wt.exe - Frame Host Mode 
-    |- wt.exe - Tab Host Mode
-       |- conhost.exe - ConPTY mode
-          |- pwsh.exe - Client application 
-```
-
-The current structure of `wt.exe` has everything hosted within the one process. To improve reliability, we would likely have to make `wt.exe` run in three modes.
-1. Manager Mode - no UI, just sits there as a broker to hold the kernel objects for a given window station/session and integrity level, accepts protocol handler routines, helps relay connections between various frame hosts when tabs move and determines where to instantiate new default-app tabs
-1. Frame Host Mode - The complete outer shell of the application outside of an individual tab. Hosts the tab bar, settings drop downs, title bar, etc.
-1. Tab Host Mode - The inner shell of an individual tab including the rendering area, scroll bar, inputs, etc.
-1. Pane Host Mode - Now that panes are a thing, we might need to go even one level deeper. Or maybe it's just a recursion on Tab Host mode.
-
-How these connect to each other is unexplored at this time.
-
-### Compatibility
-
-There are a few compatibility concerns here, primarily related to how client applications or outside utilities detect the relationship between a command-line client application and its console hosting environment.
-
-We're well aware that the process tree/hierarchy is one of the major methods used for understanding the relationship between the client and server application. However, in order to accomplish our goals here, it is inevitable that the original hosting `conhost.exe` (either started in ConPTY mode by a `wt.exe` or started by the operating system in response to an otherwise unhosted command-line application) will become orphaned or otherwise disassociated with the UI that is actually presenting it.
-
-It is possible (but would need to be explored) that the APIs available to us to reorder the parenting of the processes to put the `conhost.exe` as the parent of the `cmd.exe` (despite the fact that `cmd.exe` usually starts first as the default application and the `ConsoleInitialize` routines inside `kernelbase.dll` create the `conhost.exe`) could be reused here to shuffle around the parent/child relationships. However, it could also introduce new problems. One prior example was that the UIA trees for accessibility do **NOT** tolerate the shuffling of the parent child relationship because their communication channel sessions are often tied to the relationships of HWNDs and PIDs.
-
-#### Hierarchy Example between two Terminals (tab tearoff/merge)
-
-In the one instance, we have this process hierarchy. Two instances of Windows Terminal exist. In Terminal A, the user has started a `cmd.exe` and a `pwsh.exe` tab. In the second instance, the user has started just one `cmd.exe` tab.
-
-```
-- wt.exe (Terminal Instance A) 
-  |- conhost.exe (in PTY mode) - Hosted to A
-  |  |- cmd.exe
-  |- conhost.exe (in PTY mode) - Hosted to A
-     |- pwsh.exe <-- I will be dragged out
-
-- wt.exe (Terminal Instance B)
-  |- conhost.exe (in PTY mode) - Hosted to B 
-     |- cmd.exe 
-```
-
-When the `pwsh.exe` tab is torn off from Instance A and is dropped onto Instance B, the process hierarchy doesn't actually change. The connection details, preferences, and session metadata are passed via the IPC management channels, but to an outside observer, nothing has actually changed.
-
-```
-- wt.exe (Terminal Instance A) 
-  |- conhost.exe (in PTY mode) - Hosted to A
-  |  |- cmd.exe
-  |- conhost.exe (in PTY mode) - Hosted to B
-     |- pwsh.exe <-- I am hosted in B but I'm parented to A
-
-- wt.exe (Terminal Instance B)
-  |- conhost.exe (in PTY mode) - Hosted to B 
-     |- cmd.exe 
-```
-
-I don't believe there are provisions in the Windows OS to reparent applications to a different process.
-
-Additionally, this becomes more interesting when Terminal Instance A dies and B is still running:
-
-```
-- conhost.exe (in PTY mode) - Hosted to B
-  |- pwsh.exe <-- I am hosted in B but I'm parented to A
-
-- wt.exe (Terminal Instance B)
-  |- conhost.exe (in PTY mode) - Hosted to B 
-     |- cmd.exe 
-```
-
-When instance A dies, the `conhost.exe` that was reparented keeps running and now just appears orphaned within the process hierarchy, reporting to the top level under utilities like Process Explorer.
-
-I believe the action plan here would be to implement what we can, observe the state of the world, and correct going forward. We don't have a solid understanding of how many client applications might be impacted by this apparent change. It also might be perfectly OK because the client applications will always remain parented to the same `conhost.exe` even if those `conhost.exe`s don't report up to the correct `wt.exe`.
-
-It is also unclear whether someone might want to write a utility from the outside to discover this hierarchy. I would be inclined to not provide a way to do this without a strong case otherwise because attempting to understand the local machine process hierarchy is a great way to box yourself in when attempting to expand later to encompass remote connections.
-
-#### Hierarchy Example between Conhost and a Terminal (default application)
-
-This looks very much like the previous section where Terminal Instance B died.
-
-```
-- conhost.exe (in PTY mode) - Hosted to A
-  |- pwsh.exe
-
-- wt.exe (Terminal Instance A)
-```
-
-The `conhost.exe` was started in response to a `pwsh.exe` being started with no host. It then put itself into PTY mode and launched into a connection of `wt.exe` instance A.
-
-**ALTERNATIVELY**
-
-```
-- conhost.exe - idling
-  
-- wt.exe (Terminal Instance A)
-  |- conhost.exe (in PTY mode)
-     |- pwsh.exe
-```
-
-The `conhost.exe` at the top was launched in response to `pwsh.exe` being started with no host. It identified that `wt.exe` was running and instead shuttled the incoming connection into that `wt.exe`. `wt.exe` stood up the `conhost.exe` in PTY mode beneath itself and the client `pwsh.exe` call below that. The PTY mode `conhost.exe` uses its reparenting commands on startup to make the tree look like the above. The orphaned (originally started) `conhost.exe` waits until the connection exits before exiting itself in case someone was waiting on it.
-
-### Performance, Power, and Efficiency
-
-This is obviously less efficient than not doing it as we have to stand up servers and protocols and handlers for shuffling things about.
-
-But as long as we're creating threads and services that sleep most of the time and are only awakened on some kernel/system event, we shouldn't be wasting too much in terms of power and background resources.
-
-Additionally, `wt.exe` is worse than `conhost.exe` alone in all efficiency categories simply because it not only requires more resources to display in a "pretty" manner, but it also requires a `conhost.exe` under it in PTY mode to adapt the API calls. This is generally acceptable for end users who care more about the experience than the total performance. 
-
-It is, however, not likely to be much if any worse than just choosing to use `wt.exe` anyway over `conhost.exe`.
-
-## Potential Issues
-
-I've listed most of the issues above in their individual sections. The primary highlights are:
-1. Process tree layout - The processes in hierarchy may not make sense to someone inspecting them either visually with a tool or programmatically
-1. Process and kernel object lifetime - Applications may be counting on a specific process or object lifetime in regards to their hosting window and we might be tampering with that in how we apply job objects or shuffle around ownership to make tabs happen
-1. Default launch expectations - It is possible that test utilities or automation are counting on `conhost.exe` being the host application or that they're not ready to tolerate the potential for other applications to start. I think the interactive/non-interactive check mitigates this, but we'd have to remain concerned here.
-1. `AttachConsole` and `DetachConsole` and `AllocConsole` - I don't have the slightest idea what happens for these APIs. We would have to explore. `AttachConsole` has restrictions based on the process hierarchy. It would likely behave in interesting ways with the strange parenting order and might be a driver to why we would have to adjust the parenting of the processes (or change the API under the hood). `DetachConsole` might create an issue where a tab disappears out of the terminal and the job object causes everything to die. `AttachConsole` wouldn't necessarily be guaranteed to go back into the same `wt.exe` or a `wt.exe` at all. 
-
-## Future considerations
-
-This might unlock some sort of isolation for extensions as well. Extensions of some sort our on our own long term roadmap, but they're inherently risky to the stability and integrity of the application. If we have to go through a lot of gyrations to enable process containerization and an interprocess communication model for tab tear off and default application work, we might also be able to contain extensions the same way. This derives further from the idea of what browsers do.

+
+# Command Palette
+
+## Abstract
+
+This spec covers the addition of a "command palette" to the Windows Terminal.
+The Command Palette is a GUI that the user can activate to search for and
+execute commands. Beneficially, the command palette allows the user to execute
+commands _even if they aren't bound to a keybinding_.
+
+## Inspiration
+
+This feature is largely inspired by the "Command Palette" in text editors like
+VsCode, Sublime Text and others.
+
+This spec was initially drafted in [a
+comment](https://github.com/microsoft/terminal/issues/2046#issuecomment-514219791)
+in [#2046]. That was authored during the annual Microsoft Hackathon, where I
+proceeded to prototype the solution. This spec is influenced by things I learned
+prototyping.
+
+## Solution Design
+
+First off, for the sake of clarity, we'll rename the `command` of a keybinding
+to `action`. This will help keep the mental model between commands and actions
+clearer. When deserializing keybindings, we'll include a check for the old
+`command` key to migrate it.
+
+We'll introduce a new top-level array to the user settings, under the key
+`commands`. `commands` will contain an array of commands, each with the
+following schema:
+
+```js
+{
+    "name": string,
+    "action": string,
+    "icon": string
+    "args": object?,
+}
+```
+
+Command names should be human-friendly names of actions, though they don't need
+to necessarily be related to the action that it fires. For example, a command
+with `newTab` as the action could have `"Open New Tab"` as the name.
+
+The command will be parsed into a new class, `Command`:
+
+```c++
+class Command
+{
+    winrt::hstring Name();
+    winrt::TerminalApp::ActionAndArgs ActionAndArgs();
+    winrt::hstring IconSource();
+}
+```
+
+We'll add another structure in GlobalAppSettings to hold all these actions. It
+will just be a `std::vector<Command>` in `GlobalAppSettings`.
+
+We'll need app to be able to turn this vector into a `ListView`, or similar, so
+that we can display this list of actions. Each element in the view will be
+intrinsically associated with the `Command` object it's associated with. In
+order to support this, we'll make `Command` a winrt type that implements
+`Windows.UI.Xaml.Data.INotifyPropertyChanged`. This will let us bind the XAML
+element to the winrt type.
+
+When an element is clicked on in the list of commands, we'll raise the event
+corresponding to that `ShortcutAction`. `AppKeyBindings` already does a great
+job of dispatching `ShortcutActions` (and their associated arguments), so we'll
+re-use that. We'll pull the basic parts of dispatching `ActionAndArgs`
+callbacks into another class, `ShortcutActionDispatch`, with a single
+`PerformAction(ActionAndArgs)` method (and events for each action).
+`AppKeyBindings` will be initialized with a reference to the
+`ShortcutActionDispatch` object, so that it can call `PerformAction` on it.
+Additionally, by having a singular `ShortcutActionDispatch` instance, we won't
+need to re-hook up the ShortcutAction keybindings each time we re-load the
+settings.
+
+In `App`, when someone clicks on an item in the list, we'll get the
+`ActionAndArgs` associated with that list element, and call PerformAction on
+the app's `ShortcutActionDispatch`. This will trigger the event handler just the
+same as pressing the keybinding.
+
+### Commands for each profile?
+
+[#3879] Is a request for being able to launch a profile directly, via the
+command palette. Essentially, the user will type the name of a profile, and hit
+enter to launch that profile. I quite like this idea, but with the current spec,
+this won't work great. We'd need to manually have one entry in the command
+palette for each profile, and every time the user adds a profile, they'd need to
+update the list of commands to add a new entry for that profile as well.
+
+This is a fairly complicated addition to this feature, so I'd hold it for
+"Command Palette v2", though I believe it's solution deserves special
+consideration from the outset.
+
+I suggest that we need a mechanism by which the user can specify a single
+command that would be expanded to one command for every profile in the list of
+profiles. Consider the following sample:
+
+```json
+    "commands": [
+        {
+            "expandOn": "profiles",
+            "icon": "${profile.icon}",
+            "name": "New Tab with ${profile.name}",
+            "command": { "action": "newTab", "profile": "${profile.name}" }
+        },
+        {
+            "expandOn": "profiles",
+            "icon": "${profile.icon}",
+            "name": "New Vertical Split with ${profile.name}",
+            "command": { "action": "splitPane", "split":"vertical", "profile": "${profile.name}" }
+        }
+    ],
+```
+
+In this example:
+* The `"expandOn": "profiles"` property indicates that each command should be
+  repeated for each individual profile.
+* The `${profile.name}` value is treated as "when expanded, use the given
+  profile's name". This allows each command to use the `name` and `icon`
+  properties of a `Profile` to customize the text of the command.
+
+To ensure that this works correctly, we'll need to make sure to expand these
+commands after all the other settings have been parsed, presumably in the
+`Validate` phase. If we do it earlier, it's possible that not all the profiles
+from various sources will have been added yet, which would lead to an incomplete
+command list.
+
+We'll need to have a placeholder property to indicate that a command should be
+expanded for each `Profile`. When the command is first parsed, we'll leave the
+format strings `${...}` unexpanded at this time. Then, in the validate phase,
+when we encounter a `"expandOn": "profiles"` command, we'll remove it from the
+list, and use it as a prototype to generate commands for every `Profile` in our
+profiles list. We'll do a string find-and-replace on the format strings to
+replace them with the values from the profile, before adding the completed
+command to the list of commands.
+
+Of course, how does this work with localization? Considering the [section
+below](#localization), we'd update the built-in commands to the following:
+
+```json
+    "commands": [
+        {
+            "iterateOn": "profiles",
+            "icon": "${profile.icon}",
+            "name": { "key": "NewTabWithProfileCommandName" },
+            "command": { "action": "newTab", "profile": "${profile.name}" }
+        },
+        {
+            "iterateOn": "profiles",
+            "icon": "${profile.icon}",
+            "name": { "key": "NewVerticalSplitWithProfileCommandName" },
+            "command": { "action": "splitPane", "split":"vertical", "profile": "${profile.name}" }
+        }
+    ],
+```
+
+In this example, we'll look up the `NewTabWithProfileCommandName` resource when
+we're first parsing the command, to find a string similar to `"New Tab with
+${profile.name}"`. When we then later expand the command, we'll see the
+`${profile.name}` bit from the resource, and expand that like we normally would.
+
+Trickily, we'll need to make sure to have a helper for replacing strings like
+this that can be used for general purpose arg parsing. As you can see, the
+`profile` property of the `newTab` command also needs the name of the profile.
+Either the command validation will need to go through and update these strings
+manually, or we'll need another of enabling these `IActionArgs` classes to fill
+those parameters in based on the profile being used. Perhaps the command
+pre-expansion could just stash the json for the action, then expand it later?
+This implementation detail is why this particular feature is not slated for
+inclusion in an initial Command Palette implementation.
+
+## UI/UX Design
+
+We'll add another action that can be used to toggle the visibility of the
+command palette. Pressing that keybinding will bring up the command palette.
+
+When the command palette appears, we'll want it to appear as a single overlay
+over all of the panes of the Terminal. The drop-down will be centered
+horizontally, dropping down from the top (from the tab row). When commands are
+entered, it will be implied that they are delivered to the focused terminal
+pane. This will help avoid two problematic scenarios that could arise from
+having the command palette attache to a single pane:
+  * When attached to a single pane, it might be very easy for the UI to quickly
+    become cluttered, especially at smaller pane sizes.
+  * This avoids the "find the overlay problem" which is common in editors like
+    VS where the dialog appears attached to the active editor pane.
+
+The palette will consist of two main UI elements: a text box for searching for
+commands, and a list of commands.
+
+The list of commands will be populated with all the commands by default. Each
+command will appear like a `MenuFlyoutItem`, with an icon at the left (if it has
+one) and the name visible. When opened, the palette will automatically highlight
+the first entry in the list.
+
+The user can navigate the list of entries with the arrow keys. Hitting enter
+will close the palette and execute the action that's highlighted. Hitting escape
+will dismiss the palette, returning control to the terminal. When the palette is
+closed for any reason (executing a command, dismissing with either escape or the
+`toggleCommandPalette` keybinding), we'll clear out any search text from the
+palette, so the user can start fresh again.
+
+We'll also want to enable the command palette to be filterable, so that the user
+can type the name of a command, and the command palette will automatically
+filter the list of commands. This should be more powerful then just a simple
+string compare - the user should be able to type a search string, and get all
+the commands that match a "fuzzy search" for that string. This will allow users
+to find the command they're looking for without needing to type the entire
+command.
+
+For example, consider the following list of commands:
+
+```json
+    "commands": [
+        { "icon": null, "name": "New Tab", "action": "newTab" },
+        { "icon": null, "name": "Close Tab", "action": "closeTab" },
+        { "icon": null, "name": "Close Pane", "action": "closePane" },
+        { "icon": null, "name": "[-] Split Horizontal", "action": "splitHorizontal" },
+        { "icon": null, "name": "[ | ] Split Vertical", "action": "splitVertical" },
+        { "icon": null, "name": "Next Tab", "action": "nextTab" },
+        { "icon": null, "name": "Prev Tab", "action": "prevTab" },
+        { "icon": null, "name": "Open Settings", "action": "openSettings" },
+        { "icon": null, "name": "Open Media Controls", "action": "openTestPane" }
+    ],
+```
+
+* "open" should return both "**Open** Settings" and "**Open** Media Controls".
+* "Tab" would return "New **Tab**", "Close **Tab**", "Next **Tab**" and "Prev
+  **Tab**".
+* "P" would return "Close **P**ane", "[-] S**p**lit Horizontal", "[ | ]
+  S**p**lit Vertical", "**P**rev Tab", "O**p**en Settings" and "O**p**en Media
+  Controls".
+* Even more powerfully, "sv" would return "[ | ] Split Vertical" (by matching
+  the **S** in "Split", then the **V** in "Vertical"). This is a great example
+  of how a user could execute a command with very few keystrokes.
+
+As the user types, we should **bold** each matching character in the command
+name, to show how their input correlates to the results on screen.
+
+## Capabilities
+
+### Accessibility
+
+As the entire command palette will be a native XAML element, it'll automatically
+be hooked up to the UIA tree, allowing for screen readers to naturally find it.
+ * When the palette is opened, it will automatically receive focus.
+ * The terminal panes will not be able to be interacted with while the palette
+   is open, which will help keep the UIA tree simple while the palette is open.
+
+### Security
+
+This should not introduce any _new_ security concerns. We're relying on the
+security of jsoncpp for parsing json. Adding new keys to the settings file
+will rely on jsoncpp's ability to securely parse those json values.
+
+### Reliability
+
+We'll need to make sure that invalid commands are ignored. A command could be
+invalid because:
+* it has a null `name`, or a name with the empty string for a value.
+* it has a null `action`, or an action specified that's not an actual
+  `ShortcutAction`.
+
+We'll ignore invalid commands from the user's settings, instead of hard
+crashing. I don't believe this is a scenario that warrants an error dialog to
+indicate to the user that there's a problem with the json.
+
+### Compatibility
+
+We will need to define default _commands_ for all the existing keybinding
+commands. With #754, we could add all the actions (that make sense) as commands
+to the commands list, so that everyone wouldn't need to define them manually.
+
+### Performance, Power, and Efficiency
+
+We'll be adding a few extra XAML elements to our tree which will certainly
+increase our runtime memory footprint while the palette is open.
+
+We'll additionally be introducing a few extra json values to parse, so that could
+increase our load times (though this will likely be negligible).
+
+## Potential Issues
+
+This will first require the work in [#1205] to work properly. Right now we
+heavily lean on the "focused" element to determine which terminal is "active".
+However, when the command palette is opened, focus will move out of the terminal
+control into the command palette, which leads to some hard to debug crashes.
+
+Additionally, we'll need to ensure that the "fuzzy search" algorithm proposed
+above will work for non-english languages, where a single character might be
+multiple `char`s long. As we'll be using a standard XAML text box for input, we
+won't need to worry about handling the input ourselves.
+
+### Localization
+
+Because we'll be shipping a set of default commands with the terminal, we should
+make sure that list of commands can be localizable. Each of the names we'll give
+to the commands should be locale-specific.
+
+To facilitate this, we'll use a special type of object in JSON that will let us
+specify a resource name in JSON. We'll use a syntax like the following to
+suggest that we should load a string from our resources, as opposed to using the
+value from the file:
+
+```json
+    "commands": [
+        { "icon": null, "name": { "key": "NewTabCommandName" }, "action": "newTab" },
+        { "icon": null, "name": { "key": "CloseTabCommandKey" }, "action": "closeTab" },
+        { "icon": null, "name": { "key": "ClosePaneCommandKey" }, "action": "closePane" },
+        { "icon": null, "name": { "key": "SplitHorizontalCommandKey" }, "action": "splitHorizontal" },
+        { "icon": null, "name": { "key": "SplitVerticalCommandKey" }, "action": "splitVertical" },
+        { "icon": null, "name": { "key": "NextTabCommandKey" }, "action": "nextTab" },
+        { "icon": null, "name": { "key": "PrevTabCommandKey" }, "action": "prevTab" },
+        { "icon": null, "name": { "key": "OpenSettingsCommandKey" }, "action": "openSettings" },
+    ],
+```
+
+We'll check at parse time if the `name` property is a string or an object. If
+it's a string, we'll treat that string as the literal text. Otherwise, if it's
+an object, we'll attempt to use the `key` property of that object to look up a
+string from our `ResourceDictionary`. This way, we'll be able to ship localized
+strings for all the built-in commands, while also allowing the user to easily
+add their own commands.
+
+During the spec review process, we considered other options for localization as
+well. The original proposal included options such as having one `defaults.json`
+file per-locale, and building the Terminal independently for each locale. Those
+were not really feasible options, so we instead settled on this solution, as it
+allowed us to leverage the existing localization support provided to us by the
+platform.
+
+The `{ "key": "resourceName" }` solution proposed here was also touched on in
+[#5280].
+
+
+## Future considerations
+
+* Commands will provide an easy point for allowing an extension to add its
+  actions to the UI, without forcing the user to bind the extension's actions to
+  a keybinding
+* Also discussed in [#2046] was the potential for adding a command that inputs a
+  certain commandline to be run by the shell. I felt that was out of scope for
+  this spec, so I'm not including it in detail. I believe that would be
+  accomplished by adding a `inputCommand` action, with two args: `commandline`,
+  a string, and `suppressNewline`, an optional bool, defaulted to false. The
+  `inputCommand` action would deliver the given `commandline` as input to the
+  connection, followed by a newline (as to execute the command).
+  `suppressNewline` would prevent the newline from being added. This would work
+  relatively well, so long as you're sitting at a shell prompt. If you were in
+  an application like `vim`, this might be handy for executing a sequence of
+  vim-specific keybindings. Otherwise, you're just going to end up writing a
+  commandline to the buffer of vim. It would be weird, but not unexpected.
+* Additionally mentioned in [#2046] was the potential for profile-scoped
+  commands. While that's a great idea, I believe it's out of scope for this
+  spec.
+* Once [#754] lands, we'll need to make sure to include commands for each action
+  manually in the default settings. This will add some overhead that the
+  developer will need to do whenever they add an action. That's unfortunate, but
+  will be largely beneficial to the end user.
+* We could theoretically also display the keybinding for a certain command in
+  the `ListViewItem` for the command. We'd need some way to correlate a
+  command's action to a keybinding's action. This could be done in a follow-up
+  task.
+* We might want to alter the fuzzy-search algorithm, to give higher precedence
+  in the results list to commands with more consecutive matching characters.
+  Alternatively we could give more weight to commands where the search matched
+  the initial character of words in the command.
+  - For example: `ot` would give more weight to "**O**pen **T**ab" than
+    "**O**pen Se**t**tings").
+* Another idea for a future spec is the concept of "nested commands", where a
+  single command has many sub-commands. This would hide the children commands
+  from the entire list of commands, allowing for much more succinct top-level
+  list of commands, and allowing related commands to be grouped together.
+  - For example, I have a text editor plugin that enables rendering markdown to
+    a number of different styles. To use that command in my text editor, first I
+    hit enter on the "Render Markdown..." command, then I select which style I
+    want to render to, in another list of options. This way, I don't need to
+    have three options for "Render Markdown to github", "Render Markdown to
+    gitlab", all in the top-level list.
+  - We probably also want to allow a nested command set to be evaluated at
+    runtime somehow. Like if we had a "Open New Tab..." command that then had a
+    nested menu with the list of profiles.
+* We may want to add a button to the New Tab Button's dropdown to "Show Command
+  Palette". I'm hesitant to keep adding new buttons to that UI, but the command
+  palette is otherwise not highly discoverable.
+  - We could add another button to the UI to toggle the visibility of the
+    command palette. This was the idea initially proposed in [#2046].
+  - For both these options, we may want a global setting to hide that button, to
+    keep the UI as minimal as possible.
+* [#1571] is a request for customizing the "new tab dropdown" menu. When we get
+  to discussing that design, we should consider also enabling users to add
+  commands from their list of commands to that menu as well.

-# Non-Terminal Panes
-
-## Abstract
-
-This spec hopes to cover the work necessary to enable panes to host non-terminal
-content. It'll describe changes to the `Pane` class to support hosting arbitrary
-controls in addition to terminals.
-
-## Inspiration
-
-The primary driver for this change is to enable testing of the pane code. If a
-`Pane` can host an arbitrary class, then a use case for that would be the
-hosting of a non-xaml test class that acts like a control. This test class could
-be have its state queried, to make sure that the panes are properly delivering
-focus to the correct pane content.

-Additionally, non-terminal panes could be used to host a variety of other
-content, such as browser panes, sticky notes, text editor scratch-pads, etc.
-Some discussion of these ideas are in #644.
-
-## Solution Design
-
-We'll change the TermControl class to derive from the
-`Windows.UI.Xaml.Controls.Control` runtime class.
-* We may need to override its `FocusState` and `Focus` methods, and implement
-  them by plumbing them straight through to the fake Control the `TermControl`
-  hosts.
-* Otherwise, it might be possible that we could just remove that fake control
-  entirely.
-* We'll remove the `GetControl` method from the `TermControl`, as the
-  `TermControl` itself will now be used as the control.
-
-We'll change the Pane class to accept a `Windows.UI.Xaml.Controls.Control`
-instead of a `TermControl`.
-
-We'll additionally change the `Pane` constructor to accept an `optional<GUID>`
-as opposed to needing a GUID. For constructing panes with Terminals, we should
-pass a GUID corresponding to that settings profile. For panes that aren't
-hosting terminals however, we should pass `nullopt` as the GUID. For panes that
-are leaf nodes (panes which are hosting a control, not another pair of panes),
-if the pane has a GUID, we can assume that the control is a TermControl.
-
-When we want to host other types of content, we'll simply pass any other control
-to the Pane, and it'll render it just as it would the `TermControl`.
-
-## UI/UX Design
-
-Instead of a pane hosting a terminal, it could host _any arbitrary control_. The
-control would still be subject to the sizing provided to it by the `Pane`, but
-it could host any arbitrary content.
-
-## Capabilities
-
-### Security
-
-I don't forsee this implementation by itself raising security concerns. This
-feature is mostly concerned with adding support for arbitrary controls, not
-actually implementing some arbitrary controls.
-
-### Reliability
-
-With more possible controls in a pane than just a terminal, it's possible that
-crashes in those controls could impact the entire Terminal app's reliability.
-This would largely be out of our control, as we only author the TermControl.
-
-We may want to consider hosting each pane in it's own process, similar to how
-moder browsers will host each tab in its own process, to help isolate tabs. This
-is a bigger discussion than the feature at hand, however.
-
-### Performance, Power, and Efficiency
-
-decide to host a WebView in a pane, then it surely could impact these measures.
-I don't believe this will have a noticable impact _on its own_. Should the user
-However, I leave that discussion to the implementation of the actual alternative
-pane content itself.
-
-### Accessibility
-
-When implementing the accessibility tree for Panes, we'll need to make sure that
-for panes with arbitrary content, we properly activate their accessibility,
-should the control provide some sort of accessibility pattern.
-
-## Potential Issues
-
-* [ ] It's entirely possible that panes with non-terminal content will not be
-  able to activate keybindings from the terminal application. For example, what
-  if the hosted control wants to use Ctrl+T for its own shortcut? The current
-  keybindings model has the `TermControl` call into the App layer to see if a
-  keystroke should be handled by the app first. We may want to make sure that
-  for non-terminal controls, we add a event handler to try and have the
-  `AppKeyBindings` handle the keypress if the control doesn't. This won't solve
-  the case where the control wants to use a keybinding that is mapped by the
-  Terminal App. In that case, non-terminal controls will actually behave
-  differently from the `TermControl`. The `TermControl` will give the app the
-  first chance to handle a keybinding, while for other controls, the app will
-  give the control the first chance to handle the keypress. This may be mildly
-  confusing to end users.
-
-## Future considerations
-
-I expect this to be a major part of our (eventual) extensibility model. By
-allowing arbitrary controls to be hosted in a Tab/Pane, this will allow
-extension authors to embed their own UI experiences alongside the terminal.
-See #555 for more discussion on the extensibility/plugin subject.

-## Issue Triage & Prioritization
-
-Incoming issues/asks/etc. are triaged several times a week, labeled appropriately, and assigned to a milestone in priority order:
-
-* P0 (serious crashes, data loss, etc.) issues are scheduled to be dealt with ASAP
-* P1/2 issues/features/asks  assigned to the current or future milestone, or to the [Terminal 2.0 milestone](https://github.com/microsoft/terminal/milestone/22) for future assignment, if required to deliver a 2.0 feature
-* Issues/features/asks not on our list of 2.0 features are assigned to the [Terminal Backlog](https://github.com/microsoft/terminal/milestone/7) for subsequent triage, prioritization & scheduling.
