Migrate spelling-0.0.21 changes from main

We still need to reference MUX
    to get mdmerge happy, but we can't roll that up without rolling up the DLL
    and now we'll get duplicate types in WT.vcxproj. GAH. We'll need to have
    Remoting accept a callback to say "I encountered a commandline, someone,
    deal with it?", then have apphost register for that callback. So the flow
    is monarch->AppHost->AppLogic

-# Adding Settings to Windows Terminal
-
-Adding a setting to Windows Terminal is fairly straightforward. This guide serves as a reference on how to add a setting.
-
-## 1. Terminal Settings Model
-
-The Terminal Settings Model (`Microsoft.Terminal.Settings.Model`) is responsible for (de)serializing and exposing settings.
-
-### `INHERITABLE_SETTING` macro
-
-The `INHERITABLE_SETTING` macro can be used to implement inheritance for your new setting and store the setting in the settings model. It takes three parameters:
-- `type`: the type that the setting will be stored as
-- `name`: the name of the variable for storage
-- `defaultValue`: the value to use if the user does not define the setting anywhere
-
-### Adding a Profile setting
-
-This tutorial will add `CloseOnExitMode CloseOnExit` as a profile setting.
-
-1. In `Profile.h`, declare/define the setting:
-
-```c++
-INHERITABLE_SETTING(CloseOnExitMode, CloseOnExit, CloseOnExitMode::Graceful)
-```
-
-2. In `Profile.idl`, expose the setting via WinRT:
-
-```c++
-Boolean HasCloseOnExit();
-void ClearCloseOnExit();
-CloseOnExitMode CloseOnExit;
-```
-
-3. In `Profile.cpp`, add (de)serialization and copy logic:
-
-```c++
-// Top of file:
-// - Add the serialization key
-static constexpr std::string_view CloseOnExitKey{ "closeOnExit" };
-
-// CopySettings() or Copy():
-// - The setting is exposed in the Settings UI
-profile->_CloseOnExit = source->_CloseOnExit;
-
-// LayerJson():
-// - get the value from the JSON
-JsonUtils::GetValueForKey(json, CloseOnExitKey, _CloseOnExit);
-
-// ToJson():
-// - write the value to the JSON
-JsonUtils::SetValueForKey(json, CloseOnExitKey, _CloseOnExit);
-```
-
-  - If the setting is not a primitive type, in `TerminalSettingsSerializationHelpers.h` add (de)serialization logic for the accepted values:
-
-```c++
-// For enum values...
-JSON_ENUM_MAPPER(::winrt::Microsoft::Terminal::Settings::Model::CloseOnExitMode)
-{
-    JSON_MAPPINGS(3) = {
-        pair_type{ "always", ValueType::Always },
-        pair_type{ "graceful", ValueType::Graceful },
-        pair_type{ "never", ValueType::Never },
-    };
-};
-
-// For enum flag values...
-JSON_FLAG_MAPPER(::winrt::Microsoft::Terminal::TerminalControl::CopyFormat)
-{
-    JSON_MAPPINGS(5) = {
-        pair_type{ "none", AllClear },
-        pair_type{ "html", ValueType::HTML },
-        pair_type{ "rtf", ValueType::RTF },
-        pair_type{ "all", AllSet },
-    };
-};
-
-// NOTE: This is also where you can add functionality for...
-// - overloaded type support (i.e. accept a bool and an enum)
-// - custom (de)serialization logic (i.e. coordinates)
-```
-
-### Adding a Global setting
-
-Follow the "adding a Profile setting" instructions above, but do it on the `GlobalAppSettings` files.
-
-### Adding an Action
-
-This tutorial will add the `openSettings` action.
-
-1. In `KeyMapping.idl`, declare the action:
-
-```c++
-// Add the action to ShortcutAction
-enum ShortcutAction
-{
-    OpenSettings
-}
-```
-
-2. In `ActionAndArgs.cpp`, add serialization logic:
-
-```c++
-// Top of file:
-// - Add the serialization key
-static constexpr std::string_view OpenSettingsKey{ "openSettings" };
-
-// ActionKeyNamesMap:
-// - map the new enum to the json key
-{ OpenSettingsKey, ShortcutAction::OpenSettings },
-```
-
-3. If the action should automatically generate a name when it appears in the Command Palette...
-```c++
-// In ActionAndArgs.cpp GenerateName() --> GeneratedActionNames
-{ ShortcutAction::OpenSettings, RS_(L"OpenSettingsCommandKey") },
-
-// In Resources.resw for Microsoft.Terminal.Settings.Model.Lib,
-// add the generated name
-// NOTE: Visual Studio presents the resw file as a table.
-//       If you choose to edit the file with a text editor,
-//       the code should look something like this...
-<data name="OpenSettingsCommandKey" xml:space="preserve">
-    <value>Open settings file</value>
-</data>
-```
-
-4. If the action supports arguments...
-  - In `ActionArgs.idl`, declare the arguments
-```c++
-[default_interface] runtimeclass OpenSettingsArgs : IActionArgs
-{
-    // this declares the "target" arg
-    SettingsTarget Target { get; };
-};
-```
-  - In `ActionArgs.h`, define the new runtime class
-```c++
-struct OpenSettingsArgs : public OpenSettingsArgsT<OpenSettingsArgs>
-{
-    OpenSettingsArgs() = default;
-
-    // adds a getter/setter for your argument, and defines the json key
-    WINRT_PROPERTY(SettingsTarget, Target, SettingsTarget::SettingsFile);
-    static constexpr std::string_view TargetKey{ "target" };
-
-    public:
-        hstring GenerateName() const;
-
-        bool Equals(const IActionArgs& other)
-        {
-            auto otherAsUs = other.try_as<OpenSettingsArgs>();
-            if (otherAsUs)
-            {
-                return otherAsUs->_Target == _Target;
-            }
-            return false;
-        };
-
-        static FromJsonResult FromJson(const Json::Value& json)
-        {
-            // LOAD BEARING: Not using make_self here _will_ break you in the future!
-            auto args = winrt::make_self<OpenSettingsArgs>();
-            JsonUtils::GetValueForKey(json, TargetKey, args->_Target);
-            return { *args, {} };
-        }
-
-        IActionArgs Copy() const
-        {
-            auto copy{ winrt::make_self<OpenSettingsArgs>() };
-            copy->_Target = _Target;
-            return *copy;
-        }
-};
-```
-  - In `ActionArgs.cpp`, define `GenerateName()`. This is used to automatically generate a name when it appears in the Command Palette.
-  - In `ActionAndArgs.cpp`, add serialization logic:
-
-```c++
-// ActionKeyNamesMap --> argParsers
-{ ShortcutAction::OpenSettings, OpenSettingsArgs::FromJson },
-```
-
-### Adding an Action Argument
-
-Follow step 3 from the "adding an Action" instructions above, but modify the relevant `ActionArgs` files.
-
-## 2. Setting Functionality
-
-Now that the Terminal Settings Model is updated, Windows Terminal can read and write to the settings file. This section covers how to add functionality to your newly created setting.
-
-### App-level settings
-
-App-level settings are settings that affect the frame of Windows Terminal. Generally, these tend to be global settings. The `TerminalApp` project is responsible for presenting the frame of Windows Terminal. A few files of interest include:
-- `TerminalPage`: XAML control responsible for the look and feel of Windows Terminal
-- `AppLogic`: WinRT class responsible for window-related issues (i.e. the titlebar, focus mode, etc...)
-
-Both have access to a `CascadiaSettings` object, for you to read the loaded setting and update Windows Terminal appropriately.
-
-### Terminal-level settings
-
-Terminal-level settings are settings that affect a shell session. Generally, these tend to be profile settings. The `TerminalApp` project is responsible for packaging this settings from the Terminal Settings Model to the terminal instance. There are two kinds of settings here:
-- `IControlSettings`:
-  - These are settings that affect the `TerminalControl` (a XAML control that hosts a shell session).
-  - Examples include background image customization, interactivity behavior (i.e. selection), acrylic and font customization.
-  - The `TerminalControl` project has access to these settings via a saved `IControlSettings` member.
-- `ICoreSettings`:
-  - These are settings that affect the `TerminalCore` (a lower level object that interacts with the text buffer).
-  - Examples include initial size, history size, and cursor customization.
-  - The `TerminalCore` project has access to these settings via a saved `ICoreSettings` member.
-
-`TerminalApp` packages these settings into a `TerminalSettings : IControlSettings, ICoreSettings` object upon creating a new terminal instance. To do so, you must submit the following changes:
-- Declare the setting in `IControlSettings.idl` or `ICoreSettings.idl` (whichever is relevant to your setting). If your setting is an enum setting, declare the enum here instead of in the `TerminalSettingsModel` project.
-- In `TerminalSettings.h`, declare/define the setting...
-```c++
-// The WINRT_PROPERTY macro declares/defines a getter setter for the setting.
-// Like INHERITABLE_SETTING, it takes in a type, name, and defaultValue.
-WINRT_PROPERTY(bool, UseAcrylic, false);
-```
-- In `TerminalSettings.cpp`...
-  - update `_ApplyProfileSettings` for profile settings
-  - update `_ApplyGlobalSettings` for global settings
-  - If additional processing is necessary, that would happen here. For example, `backgroundImageAlignment` is stored as a `ConvergedAlignment` in the Terminal Settings Model, but converted into XAML's separate horizontal and vertical alignment enums for packaging.
-
-### Actions
-
-Actions are packaged as an `ActionAndArgs` object, then handled in `TerminalApp`. To add functionality for actions...
-- In the `ShortcutActionDispatch` files, dispatch an event when the action occurs...
-```c++
-// ShortcutActionDispatch.idl
-event Windows.Foundation.TypedEventHandler<ShortcutActionDispatch, Microsoft.Terminal.Settings.Model.ActionEventArgs> OpenSettings;
-
-// ShortcutActionDispatch.h
-TYPED_EVENT(OpenSettings, TerminalApp::ShortcutActionDispatch, Microsoft::Terminal::Settings::Model::ActionEventArgs);
-
-// ShortcutActionDispatch.cpp --> DoAction()
-// - dispatch the appropriate event
-case ShortcutAction::OpenSettings:
-{
-    _OpenSettingsHandlers(*this, eventArgs);
-    break;
-}
-```
-- In `TerminalPage` files, handle the event...
-```c++
-// TerminalPage.h
-// - declare the handler
-void _HandleOpenSettings(const IInspectable& sender, const Microsoft::Terminal::Settings::Model::ActionEventArgs& args);
-
-// TerminalPage.cpp --> _RegisterActionCallbacks()
-// - register the handler
-_actionDispatch->OpenSettings({ this, &TerminalPage::_HandleOpenSettings });
-
-// AppActionHandlers.cpp
-// - direct the function to the right place and call a helper function
-void TerminalPage::_HandleOpenSettings(const IInspectable& /*sender*/,
-                                       const ActionEventArgs& args)
-{
-    // NOTE: this if-statement can be omitted if the action does not support arguments
-    if (const auto& realArgs = args.ActionArgs().try_as<OpenSettingsArgs>())
-    {
-        _LaunchSettings(realArgs.Target());
-        args.Handled(true);
-    }
-}
-```
-
-`AppActionHandlers` vary based on the action you want to perform. A few useful helper functions include:
-- `_GetFocusedTab()`: retrieves the focused tab
-- `_GetActiveControl()`: retrieves the active terminal control
-- `_GetTerminalTabImpl()`: tries to cast the given tab as a `TerminalTab` (a tab that hosts a terminal instance)
-
-
-## 3. Settings UI
-
-### Exposing Enum Settings
-If the new setting supports enums, you need to expose a map of the enum and the respective value in the Terminal Settings Model's `EnumMappings`:
-
-```c++
-// EnumMappings.idl
-static Windows.Foundation.Collections.IMap<String, Microsoft.Terminal.Settings.Model.CloseOnExitMode> CloseOnExitMode { get; };
-
-// EnumMappings.h
-static winrt::Windows::Foundation::Collections::IMap<winrt::hstring, CloseOnExitMode> CloseOnExitMode();
-
-// EnumMappings.cpp
-// - this macro leverages the json enum mapper in TerminalSettingsSerializationHelper to expose
-//   the mapped values across project boundaries
-DEFINE_ENUM_MAP(Model::CloseOnExitMode, CloseOnExitMode);
-```
-
-### Binding and Localizing the Enum Setting
-
-Find the page in the Settings UI that the new setting fits best in. In this example, we are adding `LaunchMode`.
-1. In `Launch.idl`, expose the bindable setting...
-```c++
-// Expose the current value for the setting
-IInspectable CurrentLaunchMode;
-
-// Expose the list of possible values
-Windows.Foundation.Collections.IObservableVector<Microsoft.Terminal.Settings.Editor.EnumEntry> LaunchModeList { get; };
-```
-
-2. In `Launch.h`, declare the bindable enum setting...
-```c++
-// the GETSET_BINDABLE_ENUM_SETTING macro accepts...
-// - name: the name of the setting
-// - enumType: the type of the setting
-// - settingsModelName: how to retrieve the setting (use State() to get access to the settings model)
-// - settingNameInModel: the name of the setting in the terminal settings model
-GETSET_BINDABLE_ENUM_SETTING(LaunchMode, Model::LaunchMode, State().Settings().GlobalSettings, LaunchMode);
-```
-
-3. In `Launch.cpp`, populate these functions...
-```c++
-// Constructor (after InitializeComponent())
-// the INITIALIZE_BINDABLE_ENUM_SETTING macro accepts...
-// - name: the name of the setting
-// - enumMappingsName: the name from the TerminalSettingsModel's EnumMappings
-// - enumType: the type for the enum
-// - resourceSectionAndType: prefix for the localization
-// - resourceProperty: postfix for the localization
-INITIALIZE_BINDABLE_ENUM_SETTING(LaunchMode, LaunchMode, LaunchMode, L"Globals_LaunchMode", L"Content");
-```
-
-4. In `Resources.resw` for Microsoft.Terminal.Settings.Editor, add the localized text to expose each enum value. Use the following format: `<SettingGroup>_<SettingName><EnumValue>.Content`
-  - `SettingGroup`:
-    - `Globals` for global settings
-    - `Profile` for profile settings
-  - `SettingName`:
-    - the Pascal-case format for the setting type (i.e. `LaunchMode` for `"launchMode"`)
-  - `EnumValue`:
-    - the json key for the setting value, but with the first letter capitalized (i.e. `Focus` for `"focus"`)
-  - The resulting resw key should look something like this `Globals_LaunchModeFocus.Content`
-  - This is the text that will be used in your control
-
-### Updating the UI
-
-When adding a setting to the UI, make sure you follow the [UWP design guidance](https://docs.microsoft.com/windows/uwp/design/).
-
-#### Enum Settings
-
-Now, create a XAML control in the relevant XAML file. Use the following tips and tricks to style everything appropriately:
-- Wrap the control in a `ContentPresenter` adhering to the `SettingContainerStyle` style
-- Bind `SelectedItem` to the relevant `Current<Setting>` (i.e. `CurrentLaunchMode`). Ensure it's a TwoWay binding
-- Bind `ItemsSource` to `<Setting>List` (i.e. `LaunchModeList`)
-- Set the ItemTemplate to the `Enum<ControlType>Template` (i.e. `EnumRadioButtonTemplate` for radio buttons)
-- Set the style to the appropriate one in `CommonResources.xaml`
-
-```xml
-<!--Launch Mode-->
-<ContentPresenter Style="{StaticResource SettingContainerStyle}">
-    <muxc:RadioButtons x:Uid="Globals_LaunchMode"
-                       SelectedItem="{x:Bind CurrentLaunchMode, Mode="TwoWay"}"
-                       ItemsSource="{x:Bind LaunchModeList}"
-                       ItemTemplate="{StaticResource EnumRadioButtonTemplate}"
-                       Style="{StaticResource RadioButtonsSettingStyle}"/>
-</ContentPresenter>
-```
-
-To add any localized text, add a `x:Uid`, and access the relevant property via the Resources.resw file. For example, `Globals_LaunchMode.Header` sets the header for this control. You can also set the tooltip text like this:
-`Globals_DefaultProfile.[using:Windows.UI.Xaml.Controls]ToolTipService.ToolTip`.
-
-#### Non-Enum Settings
-
-Continue to reference `CommonResources.xaml` for appropriate styling and wrap the control with a similar `ContentPresenter`. However, instead of binding to the `Current<Setting>` and `<Setting>List`, bind directly to the setting via the state. Binding a setting like `altGrAliasing` should look something like this:
-```xml
-<!--AltGr Aliasing-->
-<ContentPresenter Style="{StaticResource SettingContainerStyle}">
-    <CheckBox x:Uid="Profile_AltGrAliasing"
-              IsChecked="{x:Bind State.Profile.AltGrAliasing, Mode=TwoWay}"
-              Style="{StaticResource CheckBoxSettingStyle}"/>
-</ContentPresenter>
-```
-
-#### Profile Settings
-
-If you are specifically adding a Profile setting, in addition to the steps above, you need to make the setting observable by modifying the `Profiles` files...
-```c++
-// Profiles.idl --> ProfileViewModel
-// - this declares the setting as observable using the type and the name of the setting
-OBSERVABLE_PROJECTED_SETTING(Microsoft.Terminal.Settings.Model.CloseOnExitMode, CloseOnExit);
-
-// Profiles.h --> ProfileViewModel
-// - this defines the setting as observable off of the _profile object
-OBSERVABLE_PROJECTED_SETTING(_profile, CloseOnExit);
-
-// Profiles.h --> ProfileViewModel
-// - if the setting cannot be inherited by another profile (aka missing the Clear() function), use the following macro instead:
-PERMANENT_OBSERVABLE_PROJECTED_SETTING(_profile, Guid);
-```
-
-The `ProfilePageNavigationState` holds a `ProfileViewModel`, which wraps the `Profile` object from the Terminal Settings Model. The `ProfileViewModel` makes all of the profile settings observable.
-
-### Actions

-Actions are not yet supported in the Settings UI.

-# Font features and axes of variation
-
-## Abstract
-
-This spec outlines how we can allow users to specify font features and axes of variation for fonts in Windows Terminal. Font features include things like being able to specify whether ligatures should be used as well as the specific stylistic set used for a font. Axes of variation commonly include things like weight and slant but can also include fancier things like shadow distance, depending on the font.
-
-## Inspiration
-
-Reference: [#1790](https://github.com/microsoft/terminal/issues/1790)
-
-Currently, if a font has ligatures, we offer no way for a user to disable them. Many users would like the option to do so, and would also like the ability to choose stylistic sets for fonts - for example, at the time of this writing, Cascadia Code offers 4 stylistic sets but we offer no way for users to specify any of them.
-
-In a similar vein, many fonts allow for setting variations on the font along certain attributes, commonly referred to as 'axes of variation'. We can offer users more font customization options by allowing them to configure these font variations.
-
-## Solution Design
-
-### Font features
-
-It is already possible to pass in a list of [font feature structs](https://docs.microsoft.com/en-us/windows/win32/api/dwrite/ns-dwrite-dwrite_font_feature) to DWrite for it to handle. A font feature struct contains only 2 things: 
-
-1. A font feature tag
-2. A parameter value
-
-A font feature tag is constructed using a 4-character feature tag and the parameter value defines how the feature is applied. For most features, the parameter value is simply treated as a binary value - a value of 0 means the feature is not applied and a non-zero value means the feature is applied. For example, a font feature struct like {'ss03', 1} enables stylistic set 3 for the font and a font feature struct like {'liga', 0} disables ligatures. (Technically, the feature tag is _constructed_ with the 4-character tag and is not the 4-character tag itself, but they are treated the same in the example here for brevity's sake).
-
-Currently, we pass in to DWrite a null value for the list of features to apply to the font. This causes DWrite to automatically apply a ['standard' list](https://github.com/fdwr/TextLayoutSampler/blob/master/DrawableObject.ixx#L802) of font features to the font. Naturally, passing in our own list of font features to DWrite means DWrite will _only_ apply the features we defined, and no longer apply the standard list. Since the standard list contains 11 features, we need to consider how we can allow users to specify 1 additional feature or delete 1 of the standard features without needing to redefine all the others.
-
-We will do this by allowing users to define a dictionary in their settings.json file, where the keys are the 4-character feature tags and the values are the parameter values. This dictionary will then get applied to our internal dictionary (which will contain the standard list of 11 features with their parameter values), meaning that any new key-value pairs will get added to our dictionary and any existing key-value pairs will get updated. Finally, this 'merged' dictionary will be what we use to construct the list of features to pass into DWrite.
-
-### Axes of variation
-
-Specifying axes of variation is done in an extremely similar manner to the way font features are specified - a 4-character tag is used to specify which font axis is being modified and a numerical value is provided to specify the value the axis should be set to. For example, {'slnt', 20} specifies that the 'slant' axis should be set to 20.
-
-There is also a standard list of axes of variation, and each axis has its own default. We will approach this the same way we approached font features, by allowing users to specify additional features or omit features without needing to redefine the defaults.
-
-## UI/UX Design
-
-Users will be able to add a new setting to their font objects (added in [#10433](https://github.com/microsoft/terminal/pull/10433)). The resultant font object may look something like this
-
-```json
-"font": {
-    "face": "Cascadia Code",
-    "size": 12,
-    "features": {
-        "ss03": 1,
-        "liga": 0
-    },
-    "axes": {
-        "slnt": 20.5
-    }
-}
-```
-There is one point to note here about clashing. For example, if a user has the old "weight" setting defined _as well as_ a "wght" axis defined, we will only use the "wght" axis value. We prioritize that value for a few reasons:
-
-1. It is the more recent addition to our settings model. Thus, it is likely that a user that has defined both values probably just forgot to remove the old value.
-2. It is the more precise value, it is a specific float value whereas the the old "weight" setting is an enum (that eventually gets mapped to a float value).
-
-## Capabilities
-
-### Accessibility
-
-Should not affect accessibility.
-
-### Security
-
-Should not affect security.
-
-### Reliability
-
-Aside from additional parsing required for the settings file (which inherently offers more locations for parsing to fail), we need to be careful about badly formed/non-existant feature tags or axes specified in the user-defined dictionaries. We must make sure to ignore such declarations (perhaps alongside emitting a warning to the user) and only apply those that are correctly formed and exist.
-
-### Compatibility
-
-Older versions of Windows may not have the DWrite updates that allow for defining font features and axes of variation. We must make sure to fallback to the current implementation in these cases.
-
-### Performance, Power, and Efficiency
-
-Currently when rendering a run of text, if we detect that the given run is simple we will use a shortcut to obtain the glyphs needed, skipping over an expensive `GetGlyphs` call to DWrite. However, when the default feature list is changed in any way (either by adding a new feature or removing one of the defaults), there is no way for us to detect beforehand how the font glyphs would change.
-
-This means that as long as the user requests a change to the default font feature list, we will _always_ skip the shortcut and call the expensive `GetGlyphs` function for every run of text.
-
-This will naturally cause a performance cost that we will have to bear for this feature. However, it is worth noting that there are a fair number of glyphs that will cause a run of text to be deemed "not simple" (and thus cause us to call `GetGlyphs` anyway), for example when using Cascadia Code, any run of text that has the letters 'i', 'j', 'l', 'n', 'w' or 'x' is not considered simple (because those glyphs have localized variants).
-
-## Potential Issues
-
-See performance issues above.
-
-## Future considerations
-
-DWrite additionally offers the ability to vary the font features across runs of text. However, for our initial implementation of this feature, we will only apply font features to the entire buffer. If/when we decide to allow specifying font features for particular runs of text, we can lean into our existing mechanisms of splitting up runs of text to implement that.
-
-We will also need to consider how we want to represent this in the settings UI. This is slightly more complex than other settings since users should be allowed to manually input 4-character tags.

-# Focus Pane Actions
-
-## Abstract
-
-Currently, the Terminal only allows users to navigate through panes
-_directionally_. However, we might also want to allow a user to navigate through
-panes in most recently used order ("MRU" order), or to navigate directly to a
-specific pane. This spec proposes some additional actions in order to enable
-these sorts of scenarios.
-
-## Background
-
-### Inspiration
-
-`tmux` allows the user to navigate through panes using its `select-pane`
-command. The `select-pane` command works in the following way:
-
-```
-select-pane [-DLlMmRU] [-T title] [-t target-pane]
-
-     Make pane target-pane the active pane in window target-window, or set its
-     style (with -P).  If one of -D, -L, -R, or -U is used, respectively the
-     pane below, to the left, to the right, or above the target pane is used.
-     -l is the same as using the last-pane command.
-
-     -m and -M are used to set and clear the marked pane.  There is one marked
-     pane at a time, setting a new marked pane clears the last.  The marked pane
-     is the default target for -s to join-pane, swap-pane and swap-window.
-```
-_from `man tmux`_.
-
-The Terminal currently allows the user to navigate through panes with the
-`moveFocus` action, which only accepts a `direction` to move in.
-
-Additionally, the Terminal allows movement between tabs with the `nextTab` and
-`prevTab` actions, who move between tabs either in-order or in MRU order.
-Furthermore, these actions may or may not display the "tab switcher" user
-interface, based on the value of `tabSwitcherMode`.
-
-### User Stories
-
-* **Scenario 1**: A user who wants to be able to split the window into 4 equal
-  corners from the commandline. Currently this isn't possible, because the user
-  cannot move focus during the startup actions - `split-pane` actions always end
-  up splitting the current leaf in the tree of panes. (see [#5464])
-* **Scenario 2**: A user who wants to quickly navigate to the previous pane they
-  had opened. (see [#2871])
-* **Scenario 3**: A user who wants to bind a keybinding like <kbd>alt+1</kbd>,
-  <kbd>alt+2</kbd>, etc to immediately focus the first, second, etc. pane in a
-  tab. (see [#5803])
-
-### Future Considerations
-
-There's been talk of updating the advanced tab switcher to also display panes,
-in addition to just tabs. This would allow users to navigate through the ATS
-directly to a pane, and see all the panes in a tab. Currently, `tabSwitcherMode`
-changes the behavior of `nextTab`, `prevTab` - should we just build the
-`paneSwitcherMode` directly into the action we end up designing?
-
-## Solution Design
-
-Does using the pane switcher with a theoretical `focusPane(target=id)` action
-even make sense? Certainly not! That's like `switchToTab(index=id)`, the user
-already knows which tab they want to go to, there's no reason to pop an
-ephemeral UI in front of them.
-
-Similarly, it almost certainly doesn't make sense to display the pane switcher
-while moving focus directionally. Consider moving focus with a key bound to the
-arrow keys. Displaying another UI in front of them while moving focus with the
-arrow keys would be confusing.
-
-Addressing Scenario 1 is relatively easy. So long as we add any of the proposed
-actions, including the existing `moveFocus` action as a subcommand that can be
-passed to `wt.exe`, then the user should be able to navigate through the panes
-they've created with the startup commandline, and build the tree of panes
-however they see fit.
-
-Scenario 2 is more complicated, because MRU switching is always more
-complicated. Without a UI of some sort, there's no way to switch to another pane
-in the MRU order without also updating the MRU order as you go. So this would
-almost certainly necessitate a "pane switcher", like the tab switcher.
-
-
-### Proposal A: Add next, prev to moveFocus
-
-* `moveFocus(direction="up|down|left|right|next|prev")`
-
-* **Pros**:
-  - Definitely gets the "MRU Pane Switching" scenario working
-* **Cons**:
-  - Doesn't really address any of the other scenarios
-  - How will it play with pane switching in the UI?
-  - MRU switching without a dialog to track & display the MRU stack doesn't
-    really work - this only allows to the user to navigate to the most recently
-    used pane, or through all the panes in least-recently-used order. This is
-    because switching to the MRU pane _will update the MRU pane_.
-
-❌ This proposal is no longer being considered.
-
-### Proposal B: focusNextPane, focusPrevPane with order, useSwitcher args
-
-```json
-// Focus pane 1
-// - This is sensible, no arguments here
-{ "command": { "action": "focusPane", "id": 1 } },
-
-// Focus the next MRU pane
-// - Without the switcher, this can only go one pane deep in the MRU stack
-// - presumably once there's a pane switcher, it would default to enabled?
-{ "command": { "action": "focusNextPane", "order": "mru" } },
-
-// Focus the prev inOrder pane
-// - this seems straightforward
-{ "command": { "action": "focusPrevPane", "order": "inOrder" } },
-
-// Focus the next pane, in mru order, explicitly disable the switcher
-// - The user opted in to only being able to MRU switch one deep. That's fine, that's what they want.
-{ "command": { "action": "focusNextPane", "order": "mru", "useSwitcher": false} },
-
-// Focus the prev inOrder pane, explicitly with the switcher
-// - Maybe they disabled the switcher globally, but what it on for this action?
-{ "command": { "action": "focusPrevPane", "order": "inOrder", "useSwitcher": true } },
-```
-_From [discussion in the implementation
-PR](https://github.com/microsoft/terminal/pull/8183#issuecomment-729672645)_
-
-Boiled down, that's three actions:
-* `focusPane(target=id)`
-* `focusNextPane(order="inOrder|mru", useSwitcher=true|false)`
-* `focusPrevPane(order="inOrder|mru", useSwitcher=true|false)`
-
-* **Pros**:
-  - Everything is explicit, including the option to use the pane switcher (when
-    available)
-  - Adds support for in-order pane switching
-  - No "conditional parameters" - where providing one argument makes other
-    arguments invalid or ambiguous.
-* **Cons**:
-  - Doesn't really address any of the other scenarios
-  - What does the "next most-recently-used tab" even mean? How is it different
-    than "previous most-recently-used tab"? Semantically, these are the same
-    thing!
-  - No one's even asked for in-order pane switching. Is that a UX that even
-    really makes sense?
-
-❌ This proposal is no longer being considered.
-
-> 👉 **NOTE**: At this point, we stopped considering navigating in both MRU
-> "directions", since both the next and prev MRU pane are the same thing. We're
-> now using "last" to mean "the previous MRU pane".
-
-### Proposal C: One actions, combine the args
-
-* `moveFocus(target=id|"up|down|left|right|last")`
-
-* **Pros**:
-  - Absolutely the least complicated action to author. There's only one
-    parameter, `target`.
-  - No "conditional parameters".
-* **Cons**:
-  - How do we express this in the Settings UI? Mixed-type enums work fine for
-    the font weight, where each enum value has a distinct integer value it maps
-    to, but in this case, using `id` is entirely different from the other
-    directional values
-
-❌ This proposal is no longer being considered.
-
-### Proposal D: Two actions
-
-* `focusPane(target=id)`
-* `moveFocus(direction="up|down|left|right|last")`
-
-* **Pros**:
-  - Each action does explicitly one thing.
-* **Cons**:
-  - two actions for _similar_ behavior
-  - This now forks the "Direction" enum into "MoveFocusDirection" and
-    "ResizeDirection" (because `resizePane(last)` doesn't make any sense).
-
-This proposal doesn't really have any special consideration for the pane
-switcher UX. Neither of these actions would summon the pane switcher UX.
-
-### Proposal E: Three actions
-
-* `focusPane(target=id)`
-* `moveFocus(direction="up|down|left|right")`
-* `focusLastPane(usePaneSwitcher=false|true)`
-
-In this design, neither `focusPane` nor `moveFocus` will summon the pane
-switcher UI (even once it's added). However, the `focusLastPane` one _could_,
-and subsequent keypresses could pop you through the MRU stack, while it's
-visible? The pane switcher could then display the panes for the tab in MRU
-order, and the user could just use the arrow keys to navigate the list if they
-so choose.
-
-* **Pros**:
-  - Each action does explicitly one thing.
-  - Design accounts for future pane switcher UX
-* **Cons**:
-  - Three separate actions for similar behavior
-
-❌ This proposal is no longer being considered.
-
-### Proposal F: It's literally just tmux
-
-_Also known as the "one action to rule them all" proposal_
-
-`focusPane(target=id, direction="up|down|left|right|last")`
-
-Previously, this design was avoided, because what does `focusPane(target=4,
-direction=down)` do? Does it focus pane 4, or does it move focus down?
-
-`tmux` solves this in one action by just doing both!
-
-```
-Make pane target-pane the active pane ...  If one of -D, -L, -R, or -U is used,
-respectively the pane below, to the left, to the right, or above the target pane
-is used.
-```
-_from `man tmux`_.
-
-So `focusPane(target=1, direction=up)` will attempt to focus the pane above pane
-1. This action would not summon the pane switcher UX, even for
-`focusPane(direction=last)`
-
-* **Pros**:
-  - Fewest redundant actions
-* **Cons**:
-  - Is this intuitive? That combining the params would do both, with `target`
-    happening "first"?
-  - Assumes that there will be a separate action added in the future for "Open
-    the pane switcher (with some given ordering)"
-
-
-> 👉 **NOTE**: At this point, the author considered "Do we even want a separate
-> action to engage the tab switcher with panes expanded?" Perhaps panes being
-> visible in the tab switcher is just part fo the tab switcher's behavior. Maybe
-> there shouldn't be a separate "open the tab switcher with the panes expanded
-> to the pane I'm currently on, and the panes listed in MRU order" action.
-
-❌ This proposal is no longer being considered.
-
-## Conclusion
-
-After much discussion as a team, we decided that **Proposal D** would be the
-best option. We felt that there wasn't a need to add any extra configuration to
-invoke the "pane switcher" as anything different than the "tab switcher". The
-"pane switcher" should really just exist as a part of the functionality of the
-advanced tab switcher, not as it's own thing.
-
-Additionally, we concurred that the new "direction" value should be `prev`, not
-`last`, for consistency's sake.
-
-## UI/UX Design
-
-The only real UX being added with the agreed upon design is allowing the user to
-execute an action to move to the previously active pane within a single tab. No
-additional UX (including the pane switcher) is being prescribed in this spec at
-this time.
-
-## Potential Issues
-
-<table>
-<tr>
-<td><strong>Compatibility</strong></td>
-<td>
-
-We've only adding a single enum value to an existing enum. Since we're not
-changing the meaning of any of the existing values, we do not expect any
-compatibility issues there. Additionally, we're not changing the default value
-of the `direction` param of the `moveFocus` action, so there are no further
-compatibility concerns there. Furthermore, no additional parameters are being
-added to the `moveFocus` action that would potentially give it a different
-meaning.
-
-</td>
-</tr>
-</table>
-
-In the current design, there's no way to move through all the panes with a
-single keybinding. For example, if a user wanted to bind <kbd>Alt+]</kbd> to
-move to the "next" pane, and <kbd>Alt+[</kbd> to move to the "previous" one.
-These movements would necessarily need to be in-order traversals, since there's
-no way of doing multiple MRU steps.
-
-Fortunately, no one's really asked for traversing the panes in-order, so we're
-not really worried about this. Otherwise, it would maybe make sense for `last`
-to be the "previous MRU pane", and reserve `next`/`prev` for in-order traversal.

-# Appearance configuration objects for profiles
-
-## Abstract
-
-This spec outlines how we can support 'configuration objects' in our profiles, which
-will allow us to render differently depending on the state of the control. For example, a
-control can be rendered differently if it's focused as compared to when it's unfocused.
-
-## Inspiration
-
-Reference: [#3062](https://github.com/microsoft/terminal/issues/3062)
-
-Users want there to be a more visible indicator than the one we have currently for which
-pane is focused and which panes are unfocused. This change would grant us that feature.
-
-## Solution Design
-
-The implementation design for appearance config objects centers around the recent change where inheritance was added to the
-`TerminalSettings` class in the Terminal Settings Model - i.e. different `TerminalSettings` objects can inherit from each other.
-The reason for this change was that we did not want a settings reload to erase any overrides `TermControl` may have made
-to the settings during runtime. By instead passing a child of the `TerminalSettings` object to the control, we can change
-the parent of the child during a settings reload without the overrides being erased (since those overrides live in the child).
-
-The idea behind unfocused appearance configurations is similar. We will pass in another `TerminalSettings` object to the control,
-which is simply a child that already has some overrides in it. When the control gains or loses focus, it simply switches between
-the two settings objects appropriately.
-
-### Allowed parameters
-
-For now, these states are meant to be entirely appearance-based. So, not all parameters which can be
-defined in a `Profile` can be defined in this new object (for example, we do not want parameters which
-would cause a resize in this object.) Here is the list of parameters we will allow:
-
-- Anything regarding colors: `colorScheme`, `foreground`, `background`, `cursorColor` etc
-- Anything regarding background image: `path`, `opacity`, `alignment`, `stretchMode`
-- `cursorShape`
-
-We may wish to allow further parameters in these objects in the future (like `bellStyle`?). The addition
-of further parameters can be discussed in the future and is out of scope for this spec.
-
-### Inheritance
-
-The inheritance model can be thought of as an 'all-or-nothing' approach in the sense that the `unfocusedAppearance` object
-is considered as a *single* setting instead of an object with many settings. We have chosen this model because it is cleaner
-and easier to understand than the alternative, where each setting within an `unfocusedAppearance` object has a parent from which
-it obtains its value.
-
-Note that when `TerminalApp` initializes a control, it creates a `TerminalSettings` object for that profile and passes the
-control a child of that object (so that the control can store overrides in the child, as described earlier). If an unfocused
-config is defined in the profile (or in globals/profile defaults), then `TerminalApp` will create a *child of that child*,
-put the relevant overrides in it, and pass that into the control as well. Thus, the inheritance of any undefined parameters
-in the unfocused config will be as follows:
-
-1. The unfocused config specified in the profile (or in globals/profile defaults)
-2. Overrides made by the terminal control
-3. The parent profile
-
-## UI/UX Design
-
-Users will be able to add a new setting to their profiles that will look like this:
-
-```
-"unfocusedAppearance":
-{
-    "colorScheme": "Campbell",
-    "cursorColor": "#888",
-    "cursorShape": "emptyBox",
-    "foreground": "#C0C0C0",
-    "background": "#000000"
-}
-```
-
-When certain appearance settings are changed via OSC sequences (such as the background color), only the focused/regular
-appearance will change and the unfocused one will remain unchanged. However, since the unfocused settings object inherits
-from the regular one, it will still apply the change (provided it does not define its own value for that setting).
-
-## Capabilities
-
-### Accessibility
-
-Does not affect accessibility.
-
-### Security
-
-Does not affect security.
-
-### Reliability
-
-This is another location in the settings where parsing/loading the settings may fail. However, this is the case
-for any new setting we add so I would say that this is a reasonable cost for this feature.
-
-### Compatibility
-
-Should not affect compatibility.
-
-### Performance, Power, and Efficiency
-
-Rapidly switching between many panes, causing several successive appearance changes in a short period of time, could
-potentially impact performance. However, regular/reasonable pane switching should not have a noticeable effect.
-
-## Potential Issues
-
-Inactive tabs will be 'rendered' in the background with the `UnfocusedRenderingParams` object, we need to make
-sure that switching to an inactive tab (and so causing the renderer to update with the 'normal' parameters)
-does not cause the window to flash/show a jarring indicator that the rendering values changed.
-
-## Future considerations
-
-We will need to decide how this will look in the settings UI.
-
-We may wish to add more states in the future (like 'elevated'). When that happens, we will need to deal with how
-these appearance objects can scale/layer over each other. We had a lot of discussion about this and could not find
-a suitable solution to the problem of multiple states being valid at the same time (like unfocused and elevated).
-This, along with the fact that it is uncertain if there even will be more states we would want to add led us to
-the conclusion that we should only support the unfocused state for now, and come back to this issue later. If there
-are no more states other than unfocused and elevated, we could allow combining them (like having an 'unfocused elevated' state).
-If there are more states, we could do the implementation as an extension rather than inherently supporting it.

-# Elevation Quality of Life Improvements
-
-## Abstract
-
-For a long time, we've been researching adding support to the Windows Terminal
-for running both unelevated and elevated (admin) tabs side-by-side, in the same
-window. However, after much research, we've determined that there isn't a safe
-way to do this without opening the Terminal up as a potential
-escalation-of-privilege vector.
-
-Instead, we'll be adding a number of features to the Terminal to improve the
-user experience of working in elevated scenarios. These improvements include:
-
-* A visible indicator that the Terminal window is elevated ([#1939])
-* Configuring the Terminal to always run elevated ([#632])
-* Configuring a specific profile to always open elevated ([#632])
-* Allowing new tabs, panes to be opened elevated directly from an unelevated
-  window
-* Dynamic profile appearance that changes depending on if the Terminal is
-  elevated or not. ([#1939], [#8311])
-
-## Background
-
-_This section was originally authored in the [Process Model 2.0 Spec]. Please
-refer to it there for its original context._
-
-Let's presume that you're a user who wants to be able to open an elevated tab
-within an otherwise unelevated Terminal window. We call this scenario "mixed
-elevation" - the tabs within the Terminal can be running either unelevated _or_
-elevated client applications.
-
-It wouldn't be terribly difficult for the unelevated Terminal to request the
-permission of the user to spawn an elevated client application. The user would
-see a UAC prompt, they'd accept, and then they'd be able to have an elevated
-shell alongside their unelevated tabs.
-
-However, this creates an escalation of privilege vector. Now, there's an
-unelevated window which is connected directly to an elevated process. At this
-point, **any other unelevated application could send input to the Terminal's
-`HWND`**. This would make it possible for another unelevated process to "drive"
-the Terminal window, and send commands to the elevated client application.
-
-It was initially theorized that the window/content model architecture would also
-help enable "mixed elevation". With mixed elevation, tabs could run at different
-integrity levels within the same terminal window. However, after investigation
-and research, it has become apparent that this scenario is not possible to do
-safely after all. There are numerous technical difficulties involved, and each
-with their own security risks. At the end of the day, the team wouldn't be
-comfortable shipping a mixed-elevation solution, because there's simply no way
-for us to be confident that we haven't introduced an escalation-of-privilege
-vector utilizing the Terminal. No matter how small the attack surface might be,
-we wouldn't be confident that there are _no_ vectors for an attack.
-
-Some things we considered during this investigation:
-
-* If a user requests a new elevated tab from an otherwise unelevated window, we
-  could use UAC to create a new, elevated window process, and "move" all the
-  current tabs to that window process, as well as the new elevated client. Now,
-  the window process would be elevated, preventing it from input injection, and
-  it would still contains all the previously existing tabs. The original window
-  process could now be discarded, as the new elevated window process will
-  pretend to be the original window.
-  - However, it is unfortunately not possible with COM to have an elevated
-    client attach to an unelevated server that's registered at runtime. Even in
-    a packaged environment, the OS will reject the attempt to `CoCreateInstance`
-    the content process object. this will prevent elevated windows from
-    re-connecting to unelevated client processes.
-  - We could theoretically build an RPC tunnel between content and window
-    processes, and use the RPC connection to marshal the content process to the
-    elevated window. However, then _we_ would need to be responsible for
-    securing access the the RPC endpoint, and we feel even less confident doing
-    that.
-  - Attempts were also made to use a window-broker-content architecture, with
-    the broker process having a static CLSID in the registry, and having the
-    window and content processes at mixed elevation levels `CoCreateInstance`
-    that broker. This however _also_ did not work across elevation levels. This
-    may be due to a lack of Packaged COM support for mixed elevation levels.
-
-    It's also possible that the author forgot that packaged WinRT doesn't play
-    nicely with creating objects in an elevated context. The Terminal has
-    previously needed to manually manifest all its classes in a SxS manifest for
-    Unpackaged WinRT to allow the classes to be activated, rather than relying
-    on the packaged catalog. It's theoretically possible that doing that would
-    have allowed the broker to be activated across integrity levels.
-
-    Even if this approach did end up working, we would still need to be
-    responsible for securing the elevated windows so that an unelevated attacker
-    couldn't hijack a content process and trigger unexpected code in the window
-    process. We didn't feel confident that we could properly secure this channel
-    either.
-
-We also considered allowing mixed content in windows that were _originally_
-elevated. If the window is already elevated, then it can launch new unelevated
-processes. We could allow elevated windows to still create unelevated
-connections. However, we'd want to indicate per-pane what the elevation state
-of each connection is. The user would then need to keep track themselves of
-which terminal instances are elevated, and which are not.
-
-This also marks a departure from the current behavior, where everything in an
-elevated window would be elevated by default. The user would need to specify for
-each thing in the elevated window that they'd want to create it elevated. Or the
-Terminal would need to provide some setting like
-`"autoElevateEverythingInAnElevatedWindow"`.
-
-We cannot support mixed elevation when starting in a unelevated window.
-Therefore, it doesn't make a lot of UX sense to support it in the other
-direction. It's a cleaner UX story to just have everything in a single window at
-the same elevation level.
-
-## Solution Design
-
-Instead of supporting mixed elevation in the same window, we'll introduce the
-following features to the Terminal. These are meant as a way of improving the
-quality of life for users who work in mixed-elevation (or even just elevated)
-environments.
-
-### Visible indicator for elevated windows
-
-As requested in [#1939], it would be nice if it was easy to visibly identify if
-a Terminal window was elevated or not.
-
-One easy way of doing this is by adding a simple UAC shield to the left of the
-tabs for elevated windows. This shield could be configured by the theme (see
-[#3327]). We could provide the following states:
-* Colored (the default)
-* Monochrome
-* Hidden, to hide the shield even on elevated windows. This is the current
-  behavior.
-
-![UAC-shield-in-titlebar](UAC-shield-in-titlebar.png)
-_figure 1: a monochrome UAC shield in the titlebar of the window, courtesy of @mdtauk_
-
-We could also simplify this to only allow a boolean true/false for displaying
-the shield. As we do often with other enums, we could define `true` to be the
-same as the default appearance, and `false` to be the hidden option. As always,
-the development of the Terminal is an iterative process, where we can
-incrementally improve from no setting, to a boolean setting, to a enum-backed
-one.
-
-### Configuring a profile to always run elevated
-
-Oftentimes, users might have a particular tool chain that only works when
-running elevated. In these scenarios, it would be convenient for the user to be
-able to identify that the profile should _always_ run elevated. That way, they
-could open the profile from the dropdown menu of an otherwise unelevated window
-and have the elevated window open with the profile automatically.
-
-We'll be adding the `"elevate": true|false` setting as a per-profile setting,
-with a default value of `false`. When set to `true`, we'll try to auto-elevate
-the profile whenever it's launched. We'll check to see if this window is
-elevated before creating the connection for this profile. If the window is not
-elevated, then we'll create a new window with the requested elevation level to
-handle the new connection.
-
-`"elevate": false` will do nothing. If the window is already elevated, then the
-profile won't open an un-elevated window.
-
-If the user tries to open an `"elevate": true` profile in a window that's
-already elevated, then a new tab/split will open in the existing window, rather
-than spawning an additional elevated window.
-
-There are three situations where we're creating new terminal instances: new
-tabs, new splits, and new windows. Currently, these are all actions that are
-also exposed in the `wt` commandline as subcommands. We can convert from the
-commandline arguments into these actions already. Therefore, it shouldn't be too
-challenging to convert these actions back into the equal commandline arguments.
-
-For the following examples, let's assume the user is currently in an unelevated
-Terminal window.
-
-When the user tries to create a new elevated **tab**, we'll need to create a new
-process, elevated, with the following commandline:
-
-```
-wt new-tab [args...]
-```
-
-When we create this new `wt` instance, it will obey the glomming rules as
-specified in [Session Management Spec]. It might end up glomming to another
-existing window at that elevation level, or possibly create its own window.
-
-Similarly, for a new elevated **window**, we can make sure to pass the `-w new`
-arguments to `wt`. These parameters indicate that we definitely want this
-command to run in a new window, regardless of the current glomming settings.
-
-```
-wt -w new new-tab [args...]
-```
-
-However, creating a new **pane** is a little trickier. Invoking the `wt
-split-pane [args...]` is straightforward enough.
-
-<!-- Discussion notes follow:
-If the current window doesn't have the same elevation level as the
-requested profile, do we always want to just create a new split? If the command
-ends up glomming to an existing window, does that even make sense? That invoking
-an elevated split in an unelevated window would end up splitting the elevated
-window? It's very possible that the user wanted a split in the tab they're
-currently in, in the unelevated window, but they don't want a split in the
-elevated window.
-
-What if there's not space in the elevated window to create the split (but there
-would be in the current window)? That would sure make it seem like nothing
-happened, silently.
-
-We could alternatively have cross-elevation splits default to always opening a
-new tab. That might mitigate some of the odd behaviors. Until we actually have
-support for running commands in existing windows, we'll always need to make a
-new window when running elevated. We'll need to make the new window for new tabs
-and splits, because there's no way to invoke another existing window.
-
-A third proposal is to pop a warning dialog at the user when they try to open an
-elevated split from and unelevated window. This dialog could be something like
-
-> What you requested couldn't be completed. Do you want to:
-> A. Make me a new tab instead.
-> B. Forget it and cancel. I'll go fix my config.
-
-I'm certainly leaning towards proposal 2 - always create a new tab. This is how
-it's implemented in [#8514]. In that PR, this seems to work sensibly.
--->
-
-After discussing with the team, we have decided that the most sensible approach
-for handling a cross-elevation `split-pane` is to just create a new tab in the
-elevated window. The user can always re-attach the pane as a split with the
-`move-pane` command once the new pane in the elevated window.
-
-#### Configure the Terminal to _always_ run elevated
-
-`elevate` is a per-profile property, not a global property. If a user
-wants to always have all instances of the Terminal run elevated, they
-could set `"elevate": true` in their profile defaults. That would cause _all_
-profiles they launch to always spawn as elevated windows.
-
-#### `elevate` in Actions
-
-Additionally, we'll add the `elevate` property to the `NewTerminalArgs` used in
-the `newTab`, `splitPane`, and `newWindow` actions. This is similar to how other
-properties of profiles can be overridden at launch time. This will allow
-windows, tabs and panes to all be created specifically as elevated windows.
-
-In the `NewTerminalArgs`, `elevate` will be an optional boolean, with the
-following behavior:
-* `null` (_default_): Don't modify the `elevate` property for this profile
-* `true`: This launch should act like the profile had `"elevate": true` in its
-  properties.
-* `false`: This launch should act like the profile had `"elevate": false` in its
-  properties.
-
-We'll also add an iterable command for opening a profile in an
-elevated tab, with the following json:
-
-```jsonc
-{
-    // New elevated tab...
-    "name": { "key": "NewElevatedTabParentCommandName", "icon": "UAC-Shield.png" },
-    "commands": [
-        {
-            "iterateOn": "profiles",
-            "icon": "${profile.icon}",
-            "name": "${profile.name}",
-            "command": { "action": "newTab", "profile": "${profile.name}", "elevated": true }
-        }
-    ]
-},
-```
-
-#### Elevation from the dropdown
-
-Currently, the new tab dropdown supports opening a new pane by
-<kbd>Alt+click</kbd>ing on a profile. We could similarly add support to open a
-tab elevated with <kbd>Ctrl+click</kbd>. This is similar to the behavior of the
-Windows taskbar. It supports creating an elevated instance of a program by
-<kbd>Ctrl+click</kbd>ing on entries as well.
-
-## Implementation Details
-
-### Starting an elevated process from an unelevated process
-
-It seems that we're able to create an elevated process by passing the `"runas"`
-verb to
-[`ShellExecute`](https://docs.microsoft.com/en-us/windows/win32/api/shellapi/nf-shellapi-shellexecutea).
-So we could use something like
-
-```c++
-ShellExecute(nullptr,
-             L"runas",
-             L"wt.exe",
-             L"-w new new-tab [args...]",
-             nullptr,
-             SW_SHOWNORMAL);
-```
-
-This will ask the shell to perform a UAC prompt before spawning `wt.exe` as an
-elevated process.
-
-> 👉 NOTE: This mechanism won't always work on non-Desktop SKUs of Windows. For
-> more discussion, see [Elevation on OneCore SKUs](#Elevation-on-OneCore-SKUs).

-## Potential Issues
-
-<table>
-<tr>
-<td><strong>Accessibility</strong></td>
-<td>
-
-The set of changes proposed here are not expected to introduce any new
-accessibility issues. Users can already create elevated Terminal windows. Making
-it easier to create these windows doesn't really change our accessibility story.
-
-</td>
-</tr>
-<tr>
-<td><strong>Security</strong></td>
-<td>
-
-We won't be doing anything especially unique, so there aren't expected to be any
-substantial security risks associated with these changes. Users can already
-create elevated Terminal windows, so we're not really introducing any new
-functionality, from a security perspective.
-
-We're relying on the inherent security of the `runas` verb of `ShellExecute` to
-prevent any sort of unexpected escalation-of-privilege.
-
-<hr>
-
-One security concern is the fact that the `settings.json` file is currently a
-totally unsecured file. It's completely writable by any medium-IL process. That
-means it's totally possible for a malicious program to change the file. The
-malicious program could find a user's "Elevated PowerShell" profile, and change
-the commandline to `malicious.exe`. The user might then think that their
-"Elevated PowerShell" will run `powershell.exe` elevated, but will actually
-auto-elevate this attacker.
-
-If all we expose to the user is the name of the profile in the UAC dialog, then
-there's no way for the user to be sure that the program that's about to be
-launched is actually what they expect.
-
-To help mitigate this, we should _always_ pass the evaluated `commandline` as a
-part of the call to `ShellExecute`. the arguments that are passed to
-`ShellExecute` are visible to the user, though they need to click the "More
-Details" dropdown to reveal them.
-
-We will need to mitigate this vulnerability regardless of adding support for the
-auto-elevation of individual terminal tabs/panes. If a user is launching the
-Terminal elevated (i.e. from the Win+X menu in Windows 11), then it's possible
-for a malicious program to overwrite the `commandline` of their default profile.
-The user may now unknowingly invoke this malicious program while thinking they
-are simply launching the Terminal.
-
-To deal with this more broadly, we will display a dialog within the Terminal
-window before creating **any** elevated terminal instance. In that dialog, we'll
-display the commandline that will be executed, so the user can very easily
-confirm the commandline.
-
-This will need to happen for all elevated terminal instances. For an elevated
-Windows Terminal window, this means _all_ connections made by the Terminal.
-Every time the user opens a new profile or a new commandline in a pane, we'll
-need to prompt them first to confirm the commandline. This dialog within the
-elevated window will also prevent an attacker from editing the `settings.json`
-file while the user already has an elevated Terminal window open and hijacking a
-profile.
-
-The dialog options will certainly be annoying to users who don't want to be
-taken out of their flow to confirm the commandline that they wish to launch.
-There's precedent for a similar warning being implemented by VSCode, with their
-[Workspace Trust] feature. They too faced a similar backlash when the feature
-first shipped. However, in light of recent global cybersecurity attacks, this is
-seen as an acceptable UX degradation in the name of application trust. We don't
-want to provide an avenue that's too easy to abuse.
-
-When the user confirms the commandline of this profile as something safe to run,
-we'll add it to an elevated-only version of `state.json`. (see [#7972] for more
-details). This elevated version of the file will only be accessible by the
-elevated Terminal, so an attacker cannot hijack the contents of the file. This
-will help mitigate the UX discomfort caused by prompting on every commandline
-launched. This should mean that the discomfort is only limited to the first
-elevated launch of a particular profile. Subsequent launches (without modifying
-the `commandline`) will work as they always have.
-
-The dialog for confirming these commandlines should have a link to the docs for
-"Learn more...". Transparency in the face of this dialog should
-mitigate some dissatisfaction.
-
-The dialog will _not_ appear if the user does not have a split token - if the
-user's PC does not have UAC enabled, then they're _already_ running as an
-Administrator. Everything they do is elevated, so they shouldn't be prompted in
-this way.
-
-The Settings UI should also expose a way of viewing and removing these cached
-entries. This page should only be populated in the elevated version of the
-Terminal.

-### Centennial Applications
-
-In the past, we've had a notoriously rough time with the Centennial app
-infrastructure and running the Terminal elevated. Notably, we've had to list all
-our WinRT classes in our SxS manifest so they could be activated using
-unpackaged WinRT while running elevated. Additionally, there are plenty of
-issues running the Terminal in an "over the shoulder" elevation (OTS) scenario.
-
-Specifically, we're concerned with the following scenario:
-  * the current user account has the Terminal installed,
-  * but they aren't an Administrator,
-  * the Administrator account doesn't have the Terminal installed.
-
-In that scenario, the user can run into issues launching the Terminal in an
-elevated context (even after entering the Admin's credentials in the UAC
-prompt).
-
-This spec proposes no new mitigations for dealing with these issues. It may in
-fact make them more prevalent, by making elevated contexts more easily
-accessible.
-
-Unfortunately, these issues are OS bugs that are largely out of our own control.
-We will continue to apply pressure to the centennial app team internally as we
-encounter these issues. They are are team best equipped to resolve these issues.
-
-### Default Terminal & auto-elevation
-
-In the future, when we support setting the Terminal as the "default terminal
-emulator" on Windows. When that lands, we will use the `profiles.defaults`
-settings to create the tab where we'll be hosting the commandline client. If the user has
-`"elevate": true` in their `profiles.defaults`, we'd usually try to
-auto-elevate the profile. In this scenario, however, we can't do that. The
-Terminal is being invoked on behalf of the client app launching, instead of the
-Terminal invoking the client application.
-
-**2021-08-17 edit**: Now that "defterm" has shipped, we're a little more aware
-of some of the limitations with packaged COM and elevation boundaries. Defterm
-cannot be used with elevated processes _at all_ currently (see [#10276]). When
-an elevated commandline application is launched, it will always just appear in
-`conhost.exe`. Furthermore, An unelevated peasant can't communicate with an
-elevated monarch so we can't toss the connection to the elevated monarch and
-have them handle it.
-
-The simplest solution here is to just _always_ ignore the `elevate` property for
-incoming defterm connections. This is not an ideal solution, and one that we're
-willing to revisit if/when [#10276] is ever fixed.
-
-### Elevation on OneCore SKUs
-
-This spec proposes using `ShellExecute` to elevate the Terminal window. However,
-not all Windows SKUs have support for `ShellExecute`. Notably, the non-Desktop
-SKUs, which are often referred to as "OneCore" SKUs. On these platforms, we
-won't be able to use `ShellExecute` to elevate the Terminal. There might not
-even be the concept of multiple elevation levels, or different users, depending
-on the SKU.
-
-Fortunately, this is a mostly hypothetical concern for the moment. Desktop is
-the only publicly supported SKU for the Terminal currently. If the Terminal ever
-does become available on those SKUs, we can use these proposals as mitigations.
-
-* If elevation is supported, there must be some other way of elevating a
-  process. We could always use that mechanism instead.
-* If elevation isn't supported (I'm thinking 10X is one of these), then we could
-  instead display a warning dialog whenever a user tries to open an elevated
-  profile.
-  - We could take the warning a step further. We could add another settings
-    validation step. This would warn the user if they try to mark any profiles
-    or actions as `"elevate":true`
-
-## Future considerations
-
-* If we wanted to go even further down the visual differentiation route, we
-  could consider allowing the user to set an entirely different theme ([#3327])
-  based on the elevation state. Something like `elevatedTheme`, to pick another
-  theme from the set of themes. This would allow them to force elevated windows
-  to have a red titlebar, for example.
-* Over the course of discussion concerning appearance objects ([#8345]), it
-  became clear that having separate "elevated" appearances defined for
-  `profile`s was overly complicated. This is left as a consideration for a
-  possible future extension that could handle this scenario in a cleaner way.
-* Similarly, we're going to leave [#3637] "different profiles when elevated vs
-  unelevated" for the future. This also plays into the design of "configure the
-  new tab dropdown" ([#1571]), and reconciling those two designs is out-of-scope
-  for this particular release.
-* Tangentially, we may want to have a separate Terminal icon we ship with the
-  UAC shield present on it. This would be especially useful for the tray icon.
-  Since there will be different tray icon instances for elevated and unelevated
-  windows, having unique icons may help users identify which is which.
-
-### De-elevating a Terminal
-
-the original version of this spec proposed that `"elevated":false` from an
-elevated Terminal window should create a new unelevated Terminal instance. The
-mechanism for doing this is described in [The Old New Thing: How can I launch an
-unelevated process from my elevated process, redux].
-
-This works well when the Terminal is running unpackaged. However, de-elevating a
-process does not play well with packaged centennial applications. When asking
-the OS to run the packaged application from an elevated context, the system will
-still create the child process _elevated_. This means the packaged version of
-the Terminal won't be able to create a new unelevated Terminal instance.
-
-From an internal mail thread:
-
-> App model intercepts the `CreateProcess` call and redirects it to a COM
-> service. The parent of a packaged app is not the launching app, it’s some COM
-> service. So none of the parent process nonsense will work because the
-> parameters you passed to `CreateProcess` aren’t being used to create the
-> process.
-
-If this is fixed in the future, we could theoretically re-introduce de-elevating
-a profile. The original spec proposed a `"elevated": bool?` setting, with the
-following behaviors:
-* `null` (_default_): Don't modify the elevation level when running this profile
-* `true`: If the current window is unelevated, try to create a new elevated
-  window to host this connection.
-* `false`: If the current window is elevated, try to create a new unelevated
-  window to host this connection.
-
-We could always re-introduce this setting, to supercede `elevate`.
-
-### Change profile appearance for elevated windows
-
-In [#3062] and [#8345], we're planning on allowing users to set different
-appearances for a profile whether it's focused or not. We could do similar thing
-to enable a profile to have a different appearance when elevated. In the
-simplest case, this could allow the user to set `"background": "#ff0000"`. This
-would make a profile always appear to have a red background when in an elevated
-window.
-
-The more specific details of this implementation are left to the spec
-[Configuration object for profiles].
-
-In discussion of that spec, we decided that it would be far too complicated to
-try and overload the `unfocusedAppearance` machinery for differentiating between
-elevated and unelevated versions of the same profile. Already, that would lead
-to 4 states: [`appearance`, `unfocusedAppearance`, `elevatedAppearance`,
-`elevatedUnfocusedAppearance`]. This would lead to a combinatorial explosion if
-we decided in the future that there should also be other states for a profile.
-
-This particular QoL improvement is currently being left as a future
-consideration, should someone come up with a clever way of defining
-elevated-specific settings.
-
-<!--
-Brainstorming notes for future readers:
-
-You could have a profile that layers on an existing profile, with elevated-specific settings:
-
-{
-  "name": "foo",
-  "background": "#0000ff",
-  "commandline": "cmd.exe /k echo I am unelevated"
-},
-{
-  "inheritsFrom": "foo",
-  "background": "#ff0000",
-  "elevate": true,
-  "commandline": "cmd.exe /k echo I am ELEVATED"
-}

-# Windows Terminal Session Management
-
-## Abstract
-This document is intended to serve as an addition to the [Process Model 2.0
-Spec]. That document provides a big-picture overview of changes to the entirety
-of the Windows Terminal process architecture, including both the split of
-window/content processes, as well as the introduction of monarch/peasant
-processes. The focus of that document was to identify solutions to a set of
-scenarios that were closely intertwined, and establish these solutions would
-work together, without preventing any one scenario from working. What that
-document did not do was prescribe specific solutions to the given scenarios.
-
-This document offers a deeper dive on a subset of the issues in [#5000], to
-describe specifics for managing multiple windows with the Windows Terminal. This
-includes features such as:
-
-* Run `wt` in the current window ([#4472])
-* Single Instance Mode ([#2227])
-
-## Solution Design
-
-### Monarch and Peasant Processes
-
-This document assumes the reader is already familiar with the "Monarch and
-Peasant" architecture as detailed in the [Windows Terminal Process Model 2.0
-Spec]. As a quick summary:
-
-* Every Windows Terminal window is a "Peasant" process.
-* One of the Windows Terminal window processes is also the "Monarch" process.
-  The Monarch is picked randomly from the Terminal windows, and there is only
-  ever one Monarch process at a time.
-* Peasants can communicate with the monarch when certain state changes (such as
-  their window being activated), and the monarch can send commands to any of the
-  peasants.
-
-This architecture will be used to enable each of the following scenarios.
-
-### Scenario: Open new tabs in most recently used window
-
-A common feature of many browsers is that when a web URL is clicked somewhere,
-the web page is opened as a new tab in the most recently used window of the
-browser. This functionality is often referred to as "glomming", as the new tab
-"gloms" onto the existing window.
-
-Currently, the terminal does not support such a feature - every `wt` invocation
-creates a new window. With the monarch/peasant architecture, it'll now be
-possible to enable such a scenario.
-
-As each window is activated, it will call a method on the `Monarch` object
-(hosted by the monarch process) which will indicate that "I am peasant N, and
-I've been focused". The monarch will use those method calls to update its own
-internal stack of the most recently used windows.
-
-Whenever a new `wt.exe` process is launched, that process will _first_ ask the
-monarch if it should run the commandline in an existing window, or create its
-own window.
-
-![auto-glom-wt-exe](auto-glom-wt-exe.png)
-
-If glomming is enabled, the monarch will dispatch the commandline to the
-appropriate window for them to handle instead. To the user, it'll seem as if the
-tab just opened in the most recent window.
-
-Users should certainly be able to specify if they want new instances to glom
-onto the MRU window or not. You could imagine that currently, we default to the
-hypothetical value `"windowingBehavior": "useNew"`, meaning that each new wt gets
-its own new window.
-
-If glomming is disabled, then the Monarch will call back to the peasant and tell
-it to run the provided commandline. The monarch will use the return value of
-`ExecuteCommandline` to indicate that the calling process should create a window
-and become a peasant process, and run the commandline itself.
-
-#### Glomming within the same virtual desktop
-
-When links are opened in the new Edge browser, they will only glom onto an
-existing window if that window is open in the current virtual desktop. This
-seems like a good idea of a feature for the Terminal to follow as well.
-
-There must be some way for an application to determine which virtual desktop it
-is open on. We could use that information to have the monarch track the last
-active window _per-desktop_, and only glom when there's one on the current
-desktop.
-
-We could make the `windowingBehavior` property accept a variety of
-configurations:
-
-- `"useExisting"`: always glom to the most recent window, regardless of desktop.
-- `"useExistingOnSameDesktop"`: Only glom if there's an existing window on this
-  virtual desktop, otherwise create a new window. This will be the new default
-  value.
-- `"useNew"`: Never glom, always create a new window. This is technically the
-  current behavior of the Terminal.
-
-### Handling the current working directory
-
-Consider the following scenario: the user runs `wt -d .` in the address bar of
-explorer, and the monarch determines that this new tab should be created in an
-existing window. For clarity during this example, we will label the existing
-window WT[1], and the second `wt.exe` process WT[2].
-
-An example of this scenario is given in the following diagram:
-
-![single-instance-mode-cwd](single-instance-mode-cwd.png)
-
-In this scenario, we want the new tab to be spawned in the current working
-directory of WT[2], not WT[1]. So when WT[1] is about to run the commands that
-were passed to WT[2], WT[1] will need to:
-
-* First, stash its own CWD
-* Change to the CWD of WT[2]
-* Run the commands from WT[2]
-* Then return to its original CWD.
-
-So, as a part of the interface that a peasant uses to communicate the startup
-commandline to the monarch, we should also include the current working
-directory.
-
-### Scenario: Run `wt` in the current window
-
-One often requested scenario is the ability to run a `wt.exe` commandline in the
-current window, as opposed to always creating a new window. Presume we have the
-ability to communicate between different window processes. The logical extension
-of this scenario would be "run a `wt` commandline in _any_ given WT window".
-
-Each window process will have its own unique ID assigned to it by the monarch.
-This ID will be a positive number. Windows can also have names assigned to them.
-These names are strings that the user specifies. A window will always have an
-ID, but not necessarily a name. Running a command in a given window with ID N
-should be as easy as something like:
-
-```sh
-wt.exe --window N new-tab ; split-pane
-```
-
-(or for shorthand, `wt -w N new-tab ; split-pane`).
-
-More formally, we will add the following parameter to the top-level `wt`
-command:
-
-#### `--window,-w <window-id>`
-Run these commands in the given Windows Terminal session. This enables opening
-new tabs, splits, etc. in already running Windows Terminal windows.
-* If `window-id` is `0`, run the given commands in _the current window_.
-* If `window-id` is a negative number, or the reserved name `new`, run the
-  commands in a _new_ Terminal window.
-* If `window-id` is the ID or name of an existing window, then run the
-  commandline in that window.
-* If `window-id` is _not_ the ID or name of an existing window, create a new
-  window. That window will be assigned the ID or name provided in the
-  commandline. The provided subcommands will be run in that new window.
-* If `window-id` is omitted, then obey the value of `windowingBehavior` when
-  determining which window to run the command in.
-
-_Whenever_ `wt.exe` is started, it must _always_ pass the provided commandline
-first to the monarch process for handling. This is important for glomming
-scenarios (as noted above). The monarch will parse the commandline, determine
-which window the commandline is destined for, then call `ExecuteCommandline` on
-that peasant, who will then run the command.
-
-#### Running commands in the current window:`wt --window 0`
-
-If `wt -w 0 <commands>` is run _outside_ a WT instance, it could attempt to glom
-onto _the most recent WT window_ instead. This seems more logical than something
-like `wt --window last` or some other special value indicating "run this in the
-MRU window".<sup>[[2]](#footnote-2)</sup>
-
-That might be a simple, but **wrong**, implementation for "the current window".
-If the peasants always raise an event when their window is focused, and the
-monarch keeps track of the MRU order for peasants, then one could naively assume
-that the execution of `wt -w 0 <commands>` would always return the window the
-user was typing in, the current one. However, if someone were to do something
-like `sleep 10 ; wt -w 0 <commands>`, then the user could easily focus another
-WT window during the sleep, which would cause the MRU window to not be the same
-as the window executing the command.
-
-To solve this issue, we'll  other than
-attempting to use the `WT_SESSION` environment variable. If a `wt.exe` process
-is spawned and that's in its environment variables, it could try and ask the
-monarch for the peasant who's hosting the session corresponding to that GUID.
-This is more of a theoretical solution than anything else.
-
-In the past we've been reluctant to rely too heavily on `WT_SESSION`. However,
-an environment variable does seem to be the only reliable way to be confident
-where the window was created from. We could introduce another environment
-variable instead - `WT_WINDOW_ID`. That would allow us to shortcut the session
-ID lookup. However, I worry about exposing the window ID as an environment
-variable. If we do that, users will inevitably use that instead of the `wt -0`
-alias, which should take care of the work for them. Additionally, `WT_WINDOW_ID`
-wouldn't update in the child processes as tabs are torn out of windows to create
-new windows.
-
-Both solutions are prone to the user changing the value of the variable to some
-garbage value. If they do that, this lookup will most certainly not work as
-expected. Using the session ID (a GUID) instead of the window ID (an int) makes
-it less likely that they guess the ID of an existing instance.
-
-#### Running commands in a new window:`wt --window -1` / `wt --window new`
-
-If the user passes a negative number, or the reserved name `new` to the
-`--window` parameter, then we will always create a new window for that
-commandline, regardless of the value of `windowingBehavior`. This will allow
-users to do something like `wt -w -1 new-tab` to _always_ create a new window.
-
-#### `--window` in subcommands
-
-The `--window` parameter is a setting to `wt.exe` itself, not to one of its
-subcommands (like `new-tab` or `split-pane`). This means that all of the
-subcommands in a particular `wt` commandline will all be handled by the same
-session. For example, let us consider a user who wants to open a new tab in
-window 2, and split a new pane in window 3, all at once. The user _cannot_ do
-something like:
-
-```cmd
-wt -w 2 new-tab ; -w 3 split-pane
-```
-
-Instead, the user will need to separate the commands (by whatever their shell's
-own command delimiter is) and run two different `wt.exe` instances:
-
-```cmd
-wt -w 2 new-tab & wt -w 3 split-pane
-```
-
-This is done to make the parsing of the subcommands easier, and for the internal
-passing of arguments simpler. If the `--window` parameter were a part of each
-subcommand, then each individual subcommand's parser would need to be
-enlightened about that parameter, and then it would need to be possible for any
-single part of the commandline to call out to another process. It would be
-especially tricky then to coordinate the work being done across process here.
-The source process would need some sort of way to wait for the other process to
-notify the source that a particular subcommand completed, before allowing the
-source to dispatch the next part of the commandline.
-
-Overall, this is seen as unnecessarily complex, and dispatching whole sets of
-commands as a simpler solution.
-
-### Naming Windows
-
-It's not user-friendly to rely on automatically generated, invisible numbers to
-identify windows. There's not a great way of identifying which window is which.
-The user would need to track the IDs in their head manually. Instead, we'll
-allow the user to provide a string name for the window. This name can be used to
-address a window in addition to the ID.
-
-Names can be provided on the commandline, in the original commandline. For
-example, `wt -w foo nt` would name the new window "foo". Names can also be set
-with a new action, `NameWindow`<sup>[[3]](#footnote-3)</sup>. `name-window`
-could also be used as a subcommand. For example, `wt -w 4 name-window bar` would
-name window 4 "bar".
-
-To keep identities mentally distinct, we will disallow names that are integers
-(positive or negative). This will prevent users from renaming a window to `2`,
-then having `wt -w 2` be ambiguous as to which window it refers to.
-
-Names must also be unique. If a user attempts to set the name of the window to
-an already-used name, we'll need to ignore the name change. We could also
-display a "toast" or some other type of low-impact message to the user. That
-message would have some text like: "Unable to rename window. Another window with
-that name already exists".
-
-The Terminal will reserve the name `new`. It will also reserve any names
-starting with the character `_`. The user will not be allowed to set the window
-name to any of these reserved names. Reserving `_*` allows us to add other
-keywords in the future, without introducing a breaking change.
-
-## UI/UX Design
-
-### `windowingBehavior` details
-
-The following list gives greater breakdown of the values of `windowingBehavior`,
-and how they operate:
-
-* `"windowingBehavior": "useExisting", "useExistingOnSameDesktop"`:
-  **Browser-like glomming**
-  - New instances open in the current window by default.
-  - `newWindow` opens a new window.
-  - Tabs can be torn out to create new windows.
-  - `wt -w -1` opens a new window.
-* `"windowingBehavior": "useNew"`: No auto-glomming. This is **the current
-  behavior** of the Terminal.
-  - New instances open in new windows by default
-  - `newWindow` opens a new window
-  - Tabs can be torn out to create new windows.
-  - `wt -w -1` opens a new window.
-
-We'll be changing the default behavior from `useNew` to
-`useExistingOnSameDesktop`. This will be more consistent with other tabbed
-applications.
-
-## Concerns
-

-<tr>
-<td><strong>Accessibility</strong></td>
-<td>
-
-There is no expected accessibility impact from this feature. Each window will
-handle UIA access as it normally does.
-
-In the future, we could consider exposing the window IDs and/or names via UIA.
-

-<tr>
-<td><strong>Security</strong></td>

-
-Many security concerns have already be covered in greater detail in the parent
-spec, [Process Model 2.0 Spec].
-

-a server running at the same elevation level. We don't need to worry about
-unelevated peasants connecting to the elevated Monarch, or vice-versa.
-
-</td>

-<tr>
-<td><strong>Reliability</strong></td>
-<td>
-
-We will need to be careful when working with objects hosted by another process.
-Any work we do with it MUST be in a try/catch, because at _any_ time, the other
-process could be killed. At any point, a window process could be killed. Both
-the monarch and peasant code will need to be redundant to such a scenario, and
-if the other process is killed, make sure to display an appropriate error and
-either recover or exit gracefully.
-
-In any and all these situations, we will want to try and be as verbose as
-possible in the logging. This will make tracking which process had the error
-occur easier.

-<td><strong>Compatibility</strong></td>
-<td>
-
-We will be changing the default behavior of the Terminal to auto-glom to the
-most-recently used window on the same desktop in the course of this work, which
-will be a breaking UX change. This is behavior that can be reverted with the
-`"windowingBehavior": "useNew"` setting.
-
-We acknowledge that this is a pretty massive change to the default experience of
-the Terminal. We're planning on doing some polling of users to determine which
-behavior they want by default. Additionally, we'll be staging the rollout of
-this feature, using the Preview builds of the Terminal. The release notes that
-first include it will call extra attention to this feature. We'll ask that users
-provide their feedback in a dedicated thread, so we have time to collect
-opinions from users before rolling the change out to all users.
-
-We may choose to only change the default to `useExistingOnSameDesktop` once tab
-tear out is available, so users who are particularly unhappy about this change
-can still tear out the tab (if they can't be bothered to change the setting).
-
-</td>
-</tr>
-<tr>
-<td><strong>Performance, Power, and Efficiency</strong></td>
-<td>
-
-There's no dramatic change expected here. There may be a minor delay in the
-spawning of new terminal instances, due to requiring cross-process hops for the
-communication between monarch and peasant processes.
-
-</td>
-</tr>
-</table>
-
-## Potential Issues
-
-### Mixed Elevation Levels
-
-As of December 2020, we're no longer pursuing a "mixed-elevation" scenario for
-the Terminal. This makes many of the cross-elevation scenarios simpler. Elevated
-and unelevated `wt` instances will always remain separate. The different
-elevation levels will maintain separate lists of window IDs. If the user is
-running both an elevated and unelevated window, then there will be two monarchs.
-One elevated, and the other unelevated.
-
-There will also be some edge cases when handling the commandline that will need
-special care. Say the user wanted to open a new tab in the elevated window, from
-and unelevated `explorer.exe`. That would be a commandline like:
-
-```sh
-wt -w 0 new-tab -d . --elevated
-```
-
-Typically we first determine which window the commandline is intended for, then
-dispatch it to that window. In this case, the `-w 0` will cause us to pass the
-commandline to the current unelevated window. Then, that window will try to open
-an elevated tab, fail, and create a new `wt.exe` process. This second `wt.exe`
-process will lose the `-w 0` context. It won't inform the elevated monarch that
-this commandline should be run in the active session.
-
-We will need to make sure that special care is taken when creating elevated
-instances that we maintain the `--window` parameter passed to the Terminal.
-
-### `wt` Startup Commandline Options
-
-There are a few commandline options which can be provided to `wt.exe` which
-don't make sense to pass to another session. These options include (but are not
-limited to):
-
-* `--initialSize r,c`
-* `--initialPosition x,y`
-* `--fullscreen`, `--maximized`, etc.
-
-When we're passing a commandline to another instance to handle, these arguments
-will be ignored. they only apply to the initial creation of a window.
-`--initialSize 32, 120` doesn't make sense if the window already has a size.
-
-On startup of a new window, we currently assume that the first command is always
-`new-tab`. When passing commandlines to existing windows, we won't need to make
-that assumption anymore. There will already be existing tabs.
-
-### Monarch MRU Window Tracking
-
-As stated above, the monarch is responsible for tracking the MRU window stack.
-However, when the monarch is closed, this state will be lost. The new monarch
-will be elected, but it will be unable to ask the old monarch for the MRU
-order of the windows.
-
-We had previously considered an _acceptable_ UX when this would occur. We would
-randomize the order (with the new monarch becoming the MRU window). If someone
-noticed this bug and complained, then we had a theoretical solution prepared.
-The peasants could inform not only the monarch, but _all other peasants_ when
-they become activated. This would mean all peasants are simultaneously tracking
-the MRU stack. This would mean that any given peasant would be prepared always
-to become the monarch.
-
-A simpler solution though would be to not track the MRU stack in the Monarch at
-all. Instead, each peasant could just track internally when they were last
-activated. The Monarch wouldn't track any state itself. It would be distributed
-across all the peasants. The Monarch could then iterate over the list of
-peasants and find the one with the newest `LastActivated` timestamp.
-
-Now, when a Monarch dies, the new Peasant doesn't have to come up with the stack
-itself. All the other Peasants keep their state. The new Monarch can query them
-and get the same answer the old Monarch would have.
-
-We could further optimize this by having the Monarch also track the stack. Then,
-the monarch could query the MRU window quickly. The `LastActivated` timestamps
-would only be used by a new Monarch when it is elected, to reconstruct the MRU
-stack.
-
-## Implementation Plan
-
-This is a list of actionable tasks generated as described by this spec:
-
-* [ ] Add support for `wt.exe` processes to be Monarchs and Peasants, and
-  communicate that state between themselves. This task does not otherwise add
-  any user-facing features, merely an architectural update.
-* [ ] Add support for the `windowingBehavior` setting as a boolean. Opening new
-  WT windows will conditionally glom to existing windows.
-* [ ] Add support for per-desktop `windowingBehavior`, by adding the support for
-  the enum values `"useExisting"`, `"useExistingOnSameDesktop"` and `"useNew"`.
-* [ ] Add support for `wt.exe` to pass commandlines intended for another window
-  to the monarch, then to the intended window, with the `--window,-w
-  window-id` commandline parameter.
-* [ ] Add support for targeting and naming windows via the `-w` parameter on the
-  commandline
-* [ ] Add a `NameWindow` action, subcommand that allows the user to set the name
-  for the window.
-* [ ] Add an action that will cause all windows to briefly display a overlay
-  with the current window ID and name. This would be something like the
-  "identify" feature of the Windows "Display" settings.
-
-## Future considerations
-
-* What if the user wanted to pipe a command to a pane in an existing window?
-  ```sh
-  man ping > wt -w 0 split-pane cat
-  ```
-  Is there some way for WT to pass its stdin/out handles to the child process
-  it's creating? This is _not_ related to the current spec at hand, just
-  something the author considered while writing the spec. This likely belongs
-  over in [#492], or in its own spec.
-  - Or I suppose, with less confusion, someone could run `wt -w 0 split-pane --
-    man ping > cat`. That's certainly more sensible, and wouldn't require any
-    extra work.
-* "Single Instance Mode" is a scenario in which there is only ever one single WT
-  window. A user might want this functionality to only ever allow a single
-  terminal window to be open on their desktop. This is especially frequently
-  requested in combination with "quake mode", as discussed in [#653]. When Single
-  Instance Mode is active, and the user runs a new `wt.exe` commandline, it will
-  always end up running in the existing window, if there is one.
-
-  An earlier version of this spec proposed a new value of `glomToLastWindow`.
-  (`glomToLastWindow` was later renamed `windowingBehavior`). The `always` value
-  would disable tab tear out<sup>[[1]](#footnote-1)</sup>. It would additionally
-  disable the `newWindow` action, and prevent `wt -w new` from opening a new
-  window.
-
-  In discussion, it was concluded that this setting didn't make sense. Why did the
-  `glomToLastWindow` setting change the behavior of tear out? Single Instance Mode
-  is most frequently requested in regards to quake mode. We're leaving the
-  implementation of true single instance mode to that spec.
-* It was suggested in review that we could auto-generate names for windows, from
-  some list of words. Prior art could be the URLS for gfycat.com or
-  what3words.com, which use three random words. I believe `docker` also assigns
-  names from a random selection of `adjective`+`name`. This is an interesting
-  idea, and something that could be pursued in the future.
-    - This would be a massive pain to localize though, hence why this is left as
-      a future consideration.
-* We will _need_ to provide a commandline tool to list windows and their IDs &
-  names. We're thinking a list of windows, their IDs, names, PIDs, and the title
-  of the window.
-
-  Currently we're stuck with `wt.exe` which is a GUI application, and cannot
-  print to the console. Our need is now fairly high for the ability to print
-  info to the console. To remedy this, we'll need to ship another helper exe as
-  a commandline tool for working with the terminal. The design for this is left
-  for the future.
-
-## Footnotes
-
-<a name="footnote-1"><a>[1]: While tear-out is a separate track of work from
-session management in general, this setting could be implemented along with this
-set of features, and later used to control tear out as well.
-
-<a name="footnote-2"><a>[2]: Since we're reserving the keyword `new` to mean "a
-new window", then we could also reserve `last` or `current` as an alias for "the
-current window".
-
-<a name="footnote-3"><a>[3]: We currently have two actions for renaming _tabs_
-in the Terminal: `renameTab(name)`, and `openTabRenamer()`. We will likely
-similarly need `nameWindow(name)` and `openWindowNamer()`. `openWindowNamer`
-could display a dialog to allow the user to rename the current window at
-runtime.

-# Tab Sizing
-
-## Abstract
-
-This spec outlines the tab sizing feature. This is an application-level feature that is not profile-specific (at least for now).
-
-Global properties that encompass tab sizing:
-
-* `tabWidthMode` (accepts pre-defined values for tab sizing behavior)
-* `tabWidthMin` (can never be smaller than the icon width)
-* `tabWidthMax` (can never be wider than the tab bar)
-
-Acceptable values for `tabWidthMode`:
-
-* [default] `equal` (all tabs are sized the same, regardless of tab title length)
-* `titleLength` (width of tab contains entire tab title)
-
-## Inspiration
-
-Other browsers and terminals have varying tab width behavior, so we should give people options.
-
-## Solution Design
-
-`tabWidthMode` will be a global setting that will accept the following strings:
-
-* `equal`
-    * All tabs are equal in width
-    * If the tab bar has filled, tabs will shrink as additional tabs are added
-    * Utilizes the `equal` setting from WinUI's TabView
-
-* `titleLength`
-    * Tab width varies depending on title length
-    * Width of tab will fit the whole tab title
-    * Utilizes the `sizeToContent` setting from WinUI's TabView
-
-In addition to `tabWidthMode`, the following global properties will also be available:
-
-* `tabWidthMin`
-    * Accepts an integer
-    * Value correlates to the minimum amount of pixels the tab width can be
-    * If value is less than the width of the icon, the minimum width will be the width of the icon
-    * If value is greater than the width of the tab bar, the maximum width will be the width of the tab bar
-    * If not set, the tab will have the system-defined minimum width
-
-* `tabWidthMax`
-    * Accepts an integer
-    * Value correlates to the maximum amount of pixels the tab width can be
-    * If value is less than the width of the icon, the minimum width will be the width of the icon
-    * If value is greater than the width of the tab bar, the maximum width will be the width of the tab bar
-    * If not set, the tab will have the system-defined maximum width
-
-If `tabWidthMode` is set to `titleLength`, the tab widths will fall between the `tabWidthMin` and `tabWidthMax` values if they are set, depending on the length of the tab title.
-
-If `tabWidthMode` isn't set, the default experience will be `equal`. Justification for the default experience is the results from this [twitter poll](https://twitter.com/cinnamon_msft/status/1203093459055210496).
-
-## UI/UX Design
-
-[This tweet](https://twitter.com/cinnamon_msft/status/1203094776117022720) displays how the `equal` and `titleLength` values behave for the `tabWidthMode` property.
-
-## Capabilities
-
-### Accessibility
-
-This feature could impact accessibility if the tab title isn't stored within the metadata of the tab. If the tab width is the width of the icon, then the title isn't visible. The tab title will have to be accessible by a screen reader.
-
-### Security
-
-This feature will not impact security.
-
-### Reliability
-
-This feature will not impact reliability. It provides users with additional customization options.
-
-### Compatibility
-
-This feature will not break existing compatibility.
-
-### Performance, Power, and Efficiency
-
-## Potential Issues
-
-This feature will not impact performance, power, nor efficiency.
-
-## Future considerations
-
-* Provide tab sizing options per-profile
-* A `tabWidthMode` value that will evenly divide the entirety of the tab bar by the number of open tabs
-    * i.e. One tab will take the full width of the tab bar, two tabs will each take up half the width of the tab bar, etc.

-# Quake Mode
-
-## Abstract
-
-Many existing terminals support a feature whereby a user can press a keybinding
-anywhere in the OS, and summon their terminal application. Oftentimes the act of
-summoning this window is accompanied by a "dropdown" animation, where the window
-slides in to view from the top of the screen. This global summon action is often
-referred to as "quake mode", a reference to the video game Quake, who's console
-slid in from the top.
-
-This spec addresses both of the following two issues:
-* "Quake Mode" ([#653])
-* "Minimize to tray" ([#5727])
-
-Readers should make sure to have read the [Process Model 2.0 Spec], for
-background on Monarch and Peasant processes.
-
-## Background
-
-### Inspiration
-
-For an example of the original Quake console in action, take a look at the
-following video (noisy video warning): [Quake 3 sample]. Additionally, plenty of
-existing terminal emulators support similar functionality:
-
-* **Tilda** allows the user to specify different keys to summon the window on
-  different monitors.
-* **Guake** alternatively allows the user to either summon the terminal window to
-  a specific monitor, or whichever monitor the mouse is on. Guake only allows
-  one single instance, so pressing the global hotkey always summons the same
-  instance.
-
-### User Stories
-
-The original quake mode thread (#653) is absolutely _filled_ with variations on
-how users want to be able to summon their terminal windows. These include, but
-are not limited to:
-
-* **Story A** Press a hotkey anywhere to activate the single Terminal window
-  wherever it was
-* **Story B** Press a hotkey anywhere to activate the single Terminal window _on
-  the current monitor_. If it wasn't previously on that monitor, move it there.
-* **Story C** When the Terminal is summoned using the hotkey, have it "slide in"
-  from the top. Similarly, slide out on deactivate.
-* **Story D** <kbd>Ctrl+1</kbd> to activate the terminal on monitor 1,
-  <kbd>Ctrl+2</kbd> to activate the terminal on monitor 2.
-* **Story E** Variable dropdown speed
-* **Story F** Minimize to tray, press a hotkey to activate the terminal window
-  (#5727)
-* **Story G** Terminal doesn't appear in alt+tab view, press a hotkey to
-  activate the single terminal window / the nearest terminal window (I'm not
-  sure this is distinct from the above)
-
-## Solution Design
-
-To implement this feature, we'll add the following settings:
-* a new action, named `globalSummon`.
-* a new global, app setting named `minimizeToTray`
-* a new global, app setting named `alwaysShowTrayIcon`
-* a new action, named `quakeMode`, and a specially named `_quake` window.
-
-### `globalSummon` Action
-
-The `globalSummon` action will be a keybinding the user can use to summon a
-Terminal window from anywhere in the OS. Various arguments to the action will
-specify which window is summoned, to where, and how the window should behave on
-summon.
-
-From a technical perspective, the action will work by using the
-[`RegisterHotKey`] function. This API allows us to bind a particular hotkey with
-the OS. Whenever that hotkey is pressed, our window message loop will receive a
-`WM_HOTKEY`. We'll use the payload of that window message to lookup the action
-arguments for that hotkey. Then we'll use those arguments to control which
-window is invoked, where, and how the window behaves.
-
-Since `RegisterHotKey` can only be used to register a hotkey _once_ with the OS,
-we'll need to make sure it's only ever set up by the Monarch process. We know
-that there will only ever be one Monarch for the Terminal at a time, so it's the
-perfect process to have the responsibility of managing the global hotkey.
-
-The Monarch will be responsible for calling `RegisterHotKey`, and processing the
-`WM_HOTKEY` messages. It will then dispatch method calls to the appropriate
-window to summon it. When a Monarch dies and a new process becomes the Monarch,
-the new Monarch will re-register for the hotkeys.
-
-#### Where in the settings?
-
-Since users may want to bind multiple keys to summon different windows, we'll
-need to allow the user to specify multiple keybindings simultaneously, each with
-their own set of args.
-
-We stick all the `globalSummon`s in the actions array, like they're any other
-keybinding.
-
-However, these are not keys that are handled by the TerminalApp layer itself.
-These are keys that need to be registered with the OS. So while they will be in
-the normal `KeyMap`, they will need to be retrieved from that object and
-manually passed to the window layer.
-
-> A previous iteration of this spec considered placing the `globalSummon`
-> actions in their own top-level array of the settings file, separate from the
-> keybindings. This is no longer being considered, because it would not work for
-> the case where the user has something like:
-> ```json
-> { "keys": "ctrl+c", "command": { "action": "globalSummon", "monitor": 1 } },
-> { "keys": "ctrl+v", "command": { "action": "copy" } },
-> ```
-
-#### Which window, and where?
-
-When looking at the list of requested scenarios, there are lots of different
-ways people would like to use the global summon action. Some want the most
-recent window activated, always. Others want to have one window _per monitor_.
-Some would like to move the window to where the user is currently interacting
-with the PC, and others want to activate the window where it already exists.
-Trying to properly express all these possible configurations is complex. The
-settings should be unambiguous as to what will happen when you press the
-keybinding.
-
-I believe that in order to accurately support all the variations that people
-might want, we'll need two properties in the `globalSummon` action. These
-properties will specify _which_ window we're summoning, and _where_ to summon
-the window. To try and satisfy all these scenarios, I'm proposing the following
-two arguments to the `globalSummon` action:
-
-```json
-"monitor": "any"|"toCurrent"|"toMouse"|"onCurrent"|int,
-"desktop": "any"|"toCurrent"|"onCurrent"
-```
-
-The way these settings can be combined is in a table below. As an overview:
-
-* `monitor`: This controls the monitor that the window will be summoned from/to
-  - `"any"`: Summon the MRU window, regardless of which monitor it's currently
-    on.
-  - `"toCurrent"`/omitted: (_default_): Summon the MRU window **TO** the monitor
-    with the current **foreground** window.
-  - `"toMouse"`: Summon the MRU window **TO** the monitor where the **mouse**
-    cursor is.
-  - `"onCurrent"`: Summon the MRU window **ALREADY ON** the current monitor.
-  - `int`: Summon the MRU window for the given monitor (as identified by the
-    "Identify" displays feature in the OS settings)
-
-* `desktop`: This controls how the terminal should interact with virtual desktops.
-  - `"any"`: Leave the window on whatever desktop it's already on - we'll switch
-    to that desktop as we activate the window.
-    - > NOTE: A previous version of this spec had this enum value as `null`.
-      This was changed to `"any"` for parity with the `monitor` property.
-  - `"toCurrent"`/omitted: (_default_): Move the window **to** the current
-    virtual desktop
-  - `"onCurrent"`: Only summon the window if it's **already on** the current
-    virtual desktop
-
-Neither `desktop` nor `monitor` is a required parameter - if either is omitted,
-the omitted property will default to `toCurrent`.
-
-Together, these settings interact in the following ways:
-
-<!-- This table is formatted for viewing as rendered HTML. It's too complicated
-for pure markdown, sorry. -->

-##### Stories, revisited
-
-With the above settings, let's re-examine the original user stories, and see how
-they fit into the above settings. (_Stories that are omitted aren't relevant to
-the discussion of these settings_)
-
-> When the `desktop` param is omitted below, that can be interpreted as "any
-> `desktop` value will make sense here"
-
-* **Story A** Press a hotkey anywhere to activate the single Terminal window
-  wherever it was
-  - This is `{ "monitor": "any", "desktop": "any" }`
-* **Story B** Press a hotkey anywhere to activate the single Terminal window _on
-  the current monitor_. If it wasn't previously on that monitor, move it there.
-  - This is `{ "monitor": "toCurrent" }`
-* **Story D** <kbd>Ctrl+1</kbd> to activate the terminal on monitor 1,
-  <kbd>Ctrl+2</kbd> to activate the terminal on monitor 2.
-  - This is `[ { "keys": "ctrl+1", monitor": 1 }, { "keys": "ctrl+2", monitor": 2 } ]`
-
-As some additional examples:
-
-```json
-// Go to the MRU window, wherever it is
-{ "keys": "win+1", "command":{ "action":"globalSummon", "monitor":"any", "desktop": "any" } },
-
-// activate the MRU window, and move it to this desktop & this monitor
-{ "keys": "win+2", "command":{ "action":"globalSummon", "monitor":"toCurrent", "desktop": "toCurrent" } },
-// Since "toCurrent" & "toCurrent" are the default values, just placing a single
-// entry here will bind the same behavior:
-{ "keys": "win+2", "command": "globalSummon" },
-
-// activate the MRU window on this desktop
-{ "keys": "win+3", "command":{ "action":"globalSummon", "monitor":"any", "desktop": "onCurrent" } },
-
-// Activate the MRU window on monitor 2 (from any desktop), and place it on the
-// current desktop. If there isn't one on monitor 2, make a new one.
-{ "keys": "win+4", "command":{ "action":"globalSummon", "monitor": 2, "desktop": "toCurrent" } },
-
-// Activate the MRU window on monitor 3 (ONLY THIS desktop), or make a new one.
-{ "keys": "win+5", "command":{ "action":"globalSummon", "monitor": 3, "desktop": "onCurrent" } },
-
-// Activate the MRU window on this monitor (from any desktop), and place it on
-// the current desktop. If there isn't one on this monitor, make a new one.
-{ "keys": "win+6", "command":{ "action":"globalSummon", "monitor": "onCurrent", "desktop": "toCurrent" } },
-```
-
-#### Summoning a specific window
-
-What if you want to press a keybinding to always summon a specific, named
-window? This window might not be the most recent terminal window, nor one that
-would be selected by the `monitor` and `desktop` selectors. You could name a
-window "Epona", and press `win+e` to always summon the "Epona" window.
-
-We'll add the following property to address this scenario
-
-* `"window": string|int`
-  - When omitted (_default_): Use monitor and desktop to find the appropriate
-    MRU window to summon.
-  - When provided: Always summon the window who's name or ID matches the given
-    `window` value. If no such window exists, then create a new window with that
-    name/id.
-
-When provided _with_ `monitor` and `desktop`, `window` behaves in the following
-ways:
-* `desktop`
-  - `"any"`: Go to the desktop the given window is already on.
-  - `"toCurrent"`: If the window is on another virtual desktop, then move it to
-    the currently active one.
-  - `"onCurrent"`: If the window is on another virtual desktop, then move it to
-    the currently active one.
-* `monitor`
-  - `"any"`: Leave the window on the monitor it is already on.
-  - `"toCurrent"`: If the window is on another monitor, then move it to the
-    currently active one.
-  - `"onCurrent"`: If the window is on another monitor, then move it to the
-    currently active one.
-  - `<int>`: If the window is on another monitor, then move it to the specified
-    monitor.
-
-> NOTE: You read that right, `onCurrent` and `toCurrent` both do the same thing
-> when `window` is provided. They both already know which window to select, the
-> context of moving to the "current" monitor is all that those parameters add.
-
-#### Other properties
-
-Some users would like the terminal to just appear when the global hotkey is
-pressed. Others would like the true quake-like experience, where the terminal
-window "slides-in" from the top of the monitor. Furthermore, some users would
-like to configure the speed at which that dropdown happens. To support this
-functionality, the `globalSummon` action will support the following property:
-
-* `"dropdownDuration": float`
-  - When omitted, `0`, or a negative number: No animation is used
-    when summoning the window. The summoned window is focused immediately where
-    it is.
-  - When a positive number is provided, the terminal will use that value as a
-    duration (in seconds) to slide the terminal into position when activated.
-  - The default would be some sensible value. The pane animation is .2s, so
-    `0.2` might be a reasonable default here.
-
-We could have alternatively provided a `"dropdownSpeed"` setting, that provided
-a number of pixels per second. In my opinion, that would be harder for users to
-use correctly. I believe that it's easier for users to mentally picture "I'd
-like the dropdown to last 100ms" vs "My monitor is 1504px tall, so I need to set
-this to 15040 to make the window traverse the entire display in .1s"
-
-> NOTE: `dropdownDuration` will be ignored when the user has animations disabled
-> in the OS. In that case, the terminal will just appear, as if it was set to 0.
-
-Some users might want to be able to use the global hotkey to hide the window
-when the window is already visible. This would let the hotkey act as a sort of
-global toggle for the Terminal window. Others might not like that behavior, and
-just want the action to always bring the Terminal into focus, and do nothing if
-the terminal is already focused. To facilitate both these use cases, we'll add
-the following property:
-
-* `"toggleVisibility": bool`
-  - When `true`: (_default_) When this hotkey is pressed, and the terminal
-    window is currently active, minimize the window.
-      - When `dropdownDuration` is not `0`, then the window will slide back off
-        the top at the same speed as it would come down.
-  - When `false`: When this hotkey is pressed, and the terminal window is
-    currently active, do nothing.
-
-### Quake Mode
-
-In addition to just summoning the window from anywhere, some terminals also
-support a special "quake mode" buffer or window. This window is one that closely
-emulates the console from quake:
-* It's docked to the top of the screen
-* It takes the full width of the monitor, and only the bottom can be resized
-* It often doesn't have any other UI elements, like tabs
-
-For fun, we'll also be adding a special `"_quake"` window with the same
-behavior. If the user names a window `_quake`, then it will behave in the
-following special ways:
-
-* On launch, it will ignore the `initialPosition` and
-  `initialRows`/`initialCols` setting, and instead resize to the top half of the
-  monitor.
-* On launch, it will ignore the `launchMode` setting, and always launch in focus
-  mode.
-  - Users can disable focus mode on the `_quake` window if they do want tabs.
-* It will not be resizable from any side except the bottom of the window, nor
-  will it be drag-able.
-* It will not be a valid target for the "most recent window" for window
-  glomming. If it's the only open window, with `"windowingBehavior":
-  "useExisting*"`, then a new window will be created instead.
-  - It _is_ still a valid target for something like `wt -w _quake new-tab`
-
-A window at runtime can be renamed to become the `_quake` window (if no other
-`_quake` window exists). When it does, it will resize to the position of the
-quake window, and enter focus mode.
-
-We'll also be adding a special action `quakeMode`. This action is a special case
-of the `globalSummon` action, to specifically invoke the quake window in the
-current place. It is basically the same thing as the more elaborate:
-
-```json
-{
-    "monitor": "toCurrent",
-    "desktop": "toCurrent",
-    "window": "_quake",
-    "toggleVisibility": true,
-    "dropdownDuration": 0.5
-},
-```
-
-### Minimize to Tray
-
-Many users have requested that the terminal additionally supports minimizing the
-window "to the tray icon". This is a bit like when you close the Teams window,
-but Teams is actually still running in the system tray, or the "notification
-area".
-
-![The Teams tray icon](tray-icon-000.png)
-
-_fig 1: an example of the Teams tray icon in the notification area_.
-
-When users want to be able to "minimize to the tray", they want:
-* The window to no longer appear on the taskbar
-* The window to no longer appear in the alt-tab order
-
-When minimized to the tray, it's almost as if there's no window for the Terminal
-at all. This can be combined with the global hotkey (or the tray icon's context
-menu) to quickly restore the window.
-
-The tray icon could be used for a variety of purposes. As a simple start, we
-could include the following three options:
-
-```
-Focus Terminal
----
-Windows > Window 1 - <un-named window>
-          Window 2 - "This-window-does-have-a-name"
----
-Quit
-```
-
-Just clicking on the icon would summon the recent terminal window. Right
-clicking would show the menu with "Focus Terminal", "Windows" and "Quit" in it, and
-"Windows" would have nested entries for each Terminal window.
-
-* "Focus Terminal" would do just that - summon the most recent terminal window,
-  wherever it is.
-* "Windows" would have nested popups for each open Terminal window. Each of
-  these nested entries would display the name and ID of the window. Clicking
-  them would summon that window (wherever it may be)
-* "Quit" would be akin to quit in browsers - close all open windows
-  <sup>[[1]](#footnote-1)</sup>.
-
-The tray notification would be visible always when the user has
-`"minimizeToTray": true` set in their settings. If the user has that set to
-false, but would still like the tray, they can specify `"alwaysShowTrayIcon":
-true`. That will cause the tray icon to always be added to the system tray.
-
-There's not a combination of settings where the Terminal is "minimized to the
-tray", and there's _no tray icon visible_. We don't want to let users get into a
-state where the Terminal is running, but is totally hidden from their control.
-
-From a technical standpoint, the tray icon is managed similar to the global
-hotkey. The Monarch process is responsible for setting it up, and processing the
-messages. When a Monarch dies and a new process becomes the Monarch, then it
-will re-create the tray icon.
-
-## UI/UX Design
-
-To summarize, we're proposing the following set of settings:
-
-```jsonc
-{
-    "minimizeToTray": bool,
-    "alwaysShowTrayIcon": bool,
-    "actions": [
-        {
-            "keys": KeyChord,
-            "command": {
-                "action": "globalSummon",
-                "dropdownDuration": float,
-                "toggleVisibility": bool,
-                "monitor": "any"|"toCurrent"|"onCurrent"|int,
-                "desktop": "any"|"toCurrent"|"onCurrent"
-            }
-        },
-        {
-            "keys": KeyChord,
-            "command": {
-                "action": "quakeMode"
-            }
-        }
-    ]
-}
-```
-
-## Potential Issues
-
-<table>
-
-<tr>
-<td><strong>Compatibility</strong></td>
-<td>
-
-As part of this set of changes, we'll also be allowing the <kbd>Win</kbd> key in
-keybindings. Generally, the OS reserves the Windows key for its own shortcuts.
-For example, <kbd>Win+R</kbd> for the run dialog, <kbd>Win+A</kbd> for the
-Action Center, <kbd>Win+V</kbd> for the cloud clipboard, etc. Users will now be
-able to use the win key themselves, but they should be aware that the OS has
-"first dibs" on any hotkeys involving the Windows key.
-
-</td>
-</tr>
-<tr>
-<td><strong>Mixed elevation</strong></td>
-<td>
-
-Only one app at a time gets to register for global hotkeys. However, from the
-Terminal's perspective, unelevated and elevated windows will act like different
-apps. Each privilege level has its own Monarch. The two are unable to
-communicate across the elevation boundary.
-
-This means that if the user often runs terminals in both contexts, then only one
-will have the global hotkeys bound. The naive implementation would have the
-first elevation level "win" the keybindings.
-
-A different option would be to have elevated windows not register global hotkeys
-_at all_. I don't believe that there's any sort of security implication for
-having a global hotkey for an elevated window.
-
-A third option would be to have some sort of `"whenElevated": bool?` property
-for global hotkeys. This would explicitly enable a given hotkey for unelevated
-vs elevated windows.
-* `"whenElevated": null`: behave as normal - the first context level to run wins
-* `"whenElevated": true`: only register the hotkey when running elevated
-* `"whenElevated": false`: only register the hotkey when running unelevated
-
-</td>
-</tr>
-<tr>
-<td><strong>OneCore / Windows 10X</strong></td>
-<td>
-
-I'm fairly certain that none of these APIs would work on Windows 10X at all.
-These features would have to initially be disabled in a pure UWP version of the
-Terminal, until we could find workarounds. Since the window layer is the one
-responsible for the management of the hotkeys and the tray icon, we're not too
-worried about this.
-
-</td>
-</tr>
-</table>
-
-* If there are any other applications running that have already registered
-  hotkeys with `RegisterHotKey`, then it's possible that the Terminal's attempt
-  to register that hotkey will fail. If that should happen, then we should
-  display a warning dialog to the user indicating which hotkey will not work
-  (because it's already used for something else).
-
-* Which is the "current" monitor? The one with the mouse or the one with the
-  active window? This isn't something that has an obvious answer. Guake
-  implements this feature where the "current monitor" is the one with the mouse
-  on it. At least for the first iterations of this action, that's what we'll
-  use.
-  `monitor: onCurrent|onCurrentWindow|toCurrent|<int>`
-
-* Currently, running both the Release and Preview versions of the Terminal at
-  the same time side-by-side is not generally supported. (For example, `wt.exe`
-  can only ever point at one of two.) If a user binds the same key to a
-  `globalSummon` or `quakeMode` action, then only one of the apps will actually
-  be able to successfully claim the global hotkey.
-
-## Implementation plan
-
-Currently, in [`dev/migrie/f/653-QUAKE-MODE`], I have some sample rudimentary
-code to implement quake mode support. It allows for only a single global hotkey
-that summons the MRU window, without dropdown. That would be a good place for
-anyone starting to work on this feature. From there, I imagine the following
-work would be needed:
-
-* [ ] Add a `globalSummon` action. `AppHost` would need to be able to get _all_
-  of these actions, and register all of them. Each one would need to be assigned
-  a unique ID, so `WM_HOTKEY` can identify which hotkey was pressed.
-    - This could be committed without any other args to the `globalHotkeys`. In
-      this initial version, the behavior would be summoning the MRU window,
-      where it is, no dropdown, to start with. From there, we'd add the
-      remaining properties:
-    * [ ] Add support for the `toggleVisibility` property
-    * [ ] Add support for the `desktop` property to control how window summoning
-      interacts with virtual desktops
-    * [ ] Add support for the `monitor` which monitor the window appears on.
-    * [ ] Add support for the `dropdownDuration` property
-* [ ] Add the `minimizeToTray` setting, and implement it without any sort of flyout
-    * [ ] Add a list of windows to the right-click flyout on the tray icon
-    * [ ] Add support for the `alwaysShowTrayIcon` setting
-* [ ] When the user creates a window named `_quake`, ignore the initial size,
-  position, and launch mode, and create the window in quake mode instead.
-    * [ ] Exempt the `_quake` window from window glomming
-    * [ ] Add the `quakeMode` action, which `globalSummon`'s the `_quake` window.
-    * [ ] Prevent the `_quake` window from being dragged or resized on the
-      top/left/right.
-
-
-### Future Considerations
-
-I don't believe there are any other tracked requests that are planned that
-aren't already included in this spec.
-
-* Should the tray icon's list of windows include window titles? Both the name
-  and title? Maybe something like `({name}|{id}): {title}`? I'd bet that most
-  people don't end up naming their windows.
-* Dropdown duration could be a `float|bool`, with `true`->(whatever the default
-  is), `false`->0.
-  - We could have the setting appear as a pair of radio buttons, with the first
-    disabling dropdown, and the second enabling a text box for inputting an
-    animation duration.
-* It might be an interesting idea to have the ability to dock the quake window
-  to a specific side of the monitor, not just the top. We could probably do that
-  with a global setting `"quakeModeDockSide": "top"|"left"|"bottom"|"right"` or
-  something like that.
-* We might want to pre-load the quake window into the tray icon as an entry for
-  "Quake Mode", and otherwise exclude it from the list of windows in that menu.
-* We might think of other things for the Quake Mode window in the future - this
-  spec is by no means comprehensive. For example, it might make sense for the
-  quake mode window to automatically open in "always on top" mode.
-* It was suggested that the quake mode window could auto-hide when it loses
-  focus. That's a really neat idea, but we're a little worried about the
-  implementation. What happens when the IME window gets focus? Or the Start
-  Menu? Would those end up causing the quake window to prematurely minimize
-  itself? For that reason, we're leaving this as a future consideration.
-* Perhaps there could be a top-level object in the settings like
-  ```json
-  {
-    "quakeMode": {
-        "hideOnFocusLost": true,
-        "useFocusMode": false,
-        "profile": "my quake mode profile" ,
-        "quakeModeDockSide": "bottom"
-    }
-  }
-  ```
-  That would allow the user some further customizations on the quake mode
-  behaviors.
-  - This was later converted to the idea in [#9992] - Add per-window-name global
-    settings
-* Another proposed idea was a simplification of some of the summoning modes. `{
-  "monitor": "any", "desktop": "any" }` is a little long, and maybe not the most
-  apparent naming. Perhaps we could add another property like `summonMode` that
-  would act like an alias for a `monitor`, `desktop` combo.
-  - `"summonMode": "activateInMyFace"`: `{ "monitor": "toCurrent", "desktop": "toCurrent" }`
-  - `"summonMode": "activateWherever"`: `{ "monitor": "any", "desktop": "any" }`

-# Actions Page
-
-## Abstract
-
-We need to represent actions inside the settings UI. This spec goes through the possible use cases and reasoning for including specific features for actions inside the settings UI.
-
-## Background
-
-### Inspiration
-
-It would be ideal if we could get the settings UI to have parity with the JSON file. This will take some design work if we want every feature possible in relation to actions. There is also the option of not having parity with the JSON file in order to present a simpler UX.
-
-### User Stories
-
-All of these features are possible with the JSON file. This spec will go into discussion of which (possibly all) of these user stories need to be handled by the settings UI.
-
-- Add key bindings to an action that does not already have keys assigned
-- Edit key bindings for an action
-- Remove key bindings from an action
-- Add multiple key bindings for the same action
-- Create an iterable action
-- Create a nested action
-- Choose which actions appear inside the command palette
-- See all possible actions, regardless of keys
-
-Commands with properties:
-- sendInput has "input"
-- closeOtherTabs has "index"
-- closeTabsAfter has "index"
-- renameTab has "title"*
-- setTabColor has "color"*
-- newWindow has "commandline", "startingDirectory", "tabTitle", "index", "profile"
-- splitPane has "split", "commandline", "startingDirectory", "tabTitle", "index", "profile", "splitMode", "size"
-- copy has "singleLine", "copyFormatting"
-- scrollUp has "rowsToScroll"
-- scrollDown has "rowsToScroll"
-- setColorScheme has "colorScheme"
-
-Majority of these commands listed above are intended for the command palette, so they wouldn't make much sense with keys assigned to them anyway.
-
-### Future Considerations
-
-One day we'll have actions that can be invoked by items in the dropdown menu. This setting will have to live somewhere. Also, once we get a status bar, people may want to invoke actions from there.
-
-## Solution Design
-
-### Proposal 1: Keyboard and Command Palette pages
-
-Implement a Keyboard page in place of the Actions page. Also plan for a Command Palette page in the future if it's something that's heavily requested. The Command Palette page would cover the missing use cases listed below.
-
-When users want to add a new key binding, the dropdown will list every action, regardless if it already has keys assigned. This page should show every key binding assigned to an action, even if there are multiple bindings to the same action.
-
-Users will be able to view every possible action from the command palette if they'd like.
-
-Use cases covered:
-- Add key bindings to an action that does not already have keys assigned
-- Edit key bindings for an action
-- Remove key bindings from an action
-- Add multiple key bindings for the same action
-- See all actions that have keys assigned
-
-Use cases missing:
-- Create an iterable action
-- Create a nested action
-- Choose which actions appear inside the command palette
-- See all possible actions, regardless of keys
-
-* **Pros**:
-- This allows people to edit their actions in most of their scenarios.
-- This gives us some wiggle room to cover majority of the use cases we need and seeing if people want the other use cases that are missing.
-
-* **Cons**:
-- Unfortunately we couldn't cover every single use case with this design.
-- You can't edit the properties that are on some commands, however the default commands from the command palette include options with properties anyway. For example "decrease font size" has the `delta` property already included.
-
-### Proposal 2: Have everything on one Actions page
-
-Implement an Actions page that allows you to create actions designed for the command palette as well as actions with keys.
-
-Use cases covered:
-- Add key bindings to an action that does not already have keys assigned
-- Edit key bindings for an action
-- Remove key bindings from an action
-- Add multiple key bindings for the same action
-- See all actions that have keys assigned
-- Create an iterable action
-- Create a nested action
-- Choose which actions appear inside the command palette
-- See all possible actions, regardless of keys
-
-I could not come up with a UX design that wasn't too complicated or confusing for this scenario.
-
-**Pros**:
-- There is full parity with the JSON file.
-
-**Cons**:
-- Could not come up with a simplistic design to represent all of the use cases (which makes the settings UI not as enticing since it promotes ease of use).
-
-## Conclusion
-
-We considered Proposal 2, however the design became cluttered very quickly and we agreed to create two pages and start off with Proposal 1.
-
-## UI/UX Design
-
-![Click edit on key binding](./edit-click.png)
-
-The Add new button is using the secondary color, to align with the button on the Color schemes page.
-
-![Edit key binding](./edit-keys.png)
-
-![Click add new](./add-click.png)
-
-![Add key binding](./add-keys.png)
-
-## Potential Issues
-
-This design is not 1:1 with the JSON file, so actions that don't have keys will not appear on this page. Additionally, you can't add a new action without keys with this current design.
-
-You also cannot specify properties on commands (like the `newTab` command) and these will have to be added through the JSON file. Considering there are only a few of these and we're planning to iterate on this and add a Command Palette page, we were okay with this decision.

-# Actions in the Settings Model
-
-## Abstract
-
-This spec proposes a refactor of how Windows Terminal actions are stored in the settings model.
- The new representation would mainly allow the serialization and deserialization of commands and keybindings.
-
-## Inspiration
-
-A major component that is missing from the Settings UI is the representation of keybindings and commands.
- The JSON represents both of these as a combined entry as follows:
- ```js
-{ "icon": "path/to/icon.png", "name": "Copy the selected text", "command": "copy", "keys": "ctrl+c" },
- ```
-In the example above, the copy action is...
-- bound to <kbd>ctrl+c</kbd>
-- presented as "Copy the selected text" with the "path/to/icon.png" icon
-
-However, at the time of writing this spec, the settings model represents it as...
-- (key binding) a `KeyChord` to `ActionAndArgs` entry in a `KeyMapping`
-- (command) a `Command` with an associated icon, name, and action (`ActionAndArgs`)
-
-This introduces the following issues:
-1. Serialization
-    - We have no way of knowing when a command and a key binding point to the same action. Thus, we don't
-       know when to write a "name" to the json.
-    - We also don't know if the name was auto-generated or set by the user. This can make the JSON much more bloated by
-       actions with names that would normally be autogenerated.
-2. Handling Duplicates
-    - The same action can be bound to multiple key chords. The command palette combines all of these actions into one entry
-       because they have the same name. In reality, this same action is just being referenced in different ways.
-
-## Solution Design
-
-I propose that the issues stated above be handled via the following approach.
-
-### Step 1: Consolidating actions
-
-`Command` will be updated to look like the following:
-
-```c++
-runtimeclass Command
-{
-    // The path to the icon (or icon itself, if it's an emoji)
-    String IconPath;
-
-    // The associated name. If none is defined, one is auto-generated.
-    String Name;
-
-    // The key binding that can be used to invoke this action.
-    // NOTE: We're actually holding the KeyChord instead of just the text.
-    //       KeyChordText just serializes the relevant keychord
-    Microsoft.Terminal.Control.KeyChord Keys;
-    String KeyChordText;
-
-    // The action itself.
-    ActionAndArgs ActionAndArgs;
-
-    // NOTE: nested and iterable command logic will still be here,
-    //       But they are omitted to make this section seem cleaner.
-
-    // Future Considerations:
-    // - [#6899]: Action IDs --> add an identifier here
-}
-```
-
-The goal here is to consolidate key binding actions and command palette actions into a single class.
- This will also require the following supplemental changes:
- - `Command::LayerJson`
-   - This must combine the logic of `KeyMapping::LayerJson` and `Command::LayerJson`.
- - Key Chord data
-   - Internally, store a `vector<KeyChord> _keyMappings` to keep track of all the key chords associated with this action.
-   - `RegisterKey` and `EraseKey` update `_keyMappings`, and ensure that the latest key registered is at the end of the list.
-   - `Keys()` simply returns the last entry of `_keyMappings`, which is the latest key chord this action is bound to.
-   - `KeyChordText())` is exposed to pass the text directly to the command palette.
-       This depends on `Keys` and, thus, propagate changes automatically.
- - Observable properties
-   - `Command` has observable properties today, but does not need them because `Command` will never change while the app is running. 
- - Nested and iterable commands
-   - `HasNestedCommands`, `NestedCommands{ get; }`, `IterateOn` will continue to be exposed.
-   - A setter for these customizations will not be exposed until we find it necessary (i.e. adding support for customizing it in the Settings UI)
-   - Command expansion can continue to be exposed here to reduce implementation cost.
-   - An additional `IsNestedCommand` is necessary to record a case where a nested command is being unbound `{ "commands": null, "name": "foo" }`.
-
-Overall, the `Command` class is simply being promoted to include the `KeyChord` it has.
- This allows the implementation cost of this step to be relatively small.
-
-Completion of this step should only cause relatively minor changes to anything that depends on `Command`, because
- it is largely the same class. However, key bindings will largely be impacted because we represent key bindings as
- a map of `KeyChord`s to `ActionAndArgs`. This leads us to step 2 of this process.
-
-
-### Step 2: Querying actions
-
-Key bindings and commands are deserialized by basically storing individual actions to a map.
-- `KeyMapping` is basically an `IMap<KeyChord, ActionAndArgs>` with a few extra functions. In fact, it actually
- stores key binding data to a `std::map<KeyChord, ActionAndArgs>` and directly interacts with it.
-- `Command::LayerJson` populates an `IMap<String, Command>` during deserialization as it iterates over every action.
- Note that `Command` can be interpreted as a wrapper for `ActionAndArgs` with more stuff here.
-
-It makes sense to store these actions as maps. So, following step 1 above, we can also store and expose actions
- something like the following:
-
-```c++
-runtimeclass ActionMap
-{
-    ActionAndArgs GetActionByKeyChord(KeyChord keys);
-
-    KeyChord GetKeyBindingForAction(ShortcutAction action);
-    KeyChord GetKeyBindingForAction(ShortcutAction action, IActionArgs actionArgs);
-
-    IMapView<String, Command> NameMap { get; };
-
-    // Future Considerations:
-    // - [#6899]: Action IDs --> GetActionByID()
-}
-```
-
-The getters will return null if a matching action or key chord is not found. Since iterable commands need to be expanded at in TerminalApp, we'll just expose `NameMap`, then let TerminalApp perform the expansion as they do now. Internally, we can store the actions as follows:
-
-```c++
-std::map<KeyChord, InternalActionID> _KeyMap;
-std::map<InternalActionID, Command> _ActionMap;
-```
-
-`InternalActionID` will be a hash of `ActionAndArgs` such that two `ActionAndArgs` with the same `ShortcutAction` and `IActionArgs` output the same hash value.
-
-`GetActionByKeyChord` will use `_KeyMap` to find the `InternalActionID`, then use the `_ActionMap` to find the bound `Command`.
-`GetKeyBindingForAction` will hash the provided `ActionAndArgs` (constructed by the given parameters) and check `_ActionMap` for the given `InternalActionID`.
-
-`NameMap` will need to ensure every action in `_ActionMap` is added to the output name map if it has an associated name. This is done by simply iterating over `_ActionMap`. Nested commands must be added separately because they cannot be hashed.
-
-`ActionMap` will have an `AddAction(Command cmd)` that will update the internal state whenever a command is registered. If the given command is valid, we will check for collisions and resolve them. Otherwise, we will consider this an "unbound" action and update the internal state normally. It is important that we don't handle "unbound" actions differently because this ensures that we are explicitly unbinding a key chord.
-
-### Step 3: Settings UI needs
-
-After the former two steps are completed, the new representation of actions in the settings model is now on-par with
- what we have today. In order to bind these new actions to the Settings UI, we need the following:
-
-1. Exposing the maps
-    - `ActionMap::KeyBindings` and `ActionMap::Commands` may need to be added to pass the full list of actions to the Settings UI.
-    - In doing this, we can already update the Settings UI to include a better view of our actions.
-2. Creating a copy of the settings model
-    - The Settings UI operates by binding the XAML controls to a copy of the settings model.
-    - Copying the `ActionMap` is fairly simple. Just copy the internal state and ensure that `Command::Copy` is called such that no reference to the original WinRT objects persist. Since we are using `InternalActionID`, we will not have to worry about multiple `Command` references existing within the same `ActionMap`.
-3. Modifying the `Command`s
-    - `ActionMap` must be responsible for changing `Command`s so that we can ensure `ActionMap` always has a correct internal state:
-        - It is important that `Command` only exposes getters (not setters) to ensure `ActionMap` is up to date.
-        - If a key chord is being changed, update the `_KeyMap` and the `Command` itself.
-        - If a key binding is being deleted, add an unbound action to the given key chord.
-    - This is similar to how color schemes are maintained today.
-    - In the event that name/key-chord is set to something that's already taken, we need to propagate those changes to
-       the rest of `ActionMap`. As we do with the JSON, we respect the last name/key-chord set by the user. See [Modifying Actions](#modifying-actions)
-       in potential issues.
-    - For the purposes of the key bindings page, we will introduce a `KeyBindingViewModel` to serve as an intermediator between the settings UI and the settings model. The view model will be responsible for things like...
-       - exposing relevant information to the UI controls
-       - converting UI control interactions into proper API calls to the settings model 
-4. Serialization
-    - `Command::ToJson()` and `ActionMap::ToJson()` should perform most of the work for us. Simply iterate over the `_ActionMap` and call `Command::ToJson` on each action.
-    - See [Unbinding actions](#unbinding-actions) in potential issues.

-## Potential Issues
-
-### Layering Actions
-
-We need a way to determine where an action came from to minimize how many actions we serialize when we
- write to disk. This is a two part approach that happens as we're loading the settings
- 1. Load defaults.json
-     - For each of the actions in the JSON...
-         - Construct the `Command` (basically the `Command::LayerJson` we have today)
-         - Add it to the `ActionMap`
-           - this should update the internal state of `ActionMap` appropriately
-           - if the newly added key chord conflicts with a pre-existing one,
-              redirect `_KeyMap` to the newly added `Command` instead,
-              and update the conflicting one.
-2. Load settings.json
-     - Create a child for the `ActionMap`
-         - The purpose of a parent is to continue a search when the current `ActionMap` can't find a `Command` for a query. The parent is intended to be immutable.
-     - Load the actions array like normal into the child (see step 1)
-
-Introducing a parent mechanism to `ActionMap` allows it to understand where a `Command` came from. This allows us to minimize the number of actions we serialize when we write to disk, as opposed to serializing the entire list of actions.
-
-`ActionMap` queries will need to check their parent when they cannot find a matching `InternalActionID` in their `_ActionMap`.
-
-Since `NameMap` is generated upon request, we will need to use a `std::set<InternalActionID>` as we generate the `NameMap`. This will ensure that each `Command` is only added to the `NameMap` once. The name map will be generated as follows:
-1. Get an accumulated list of `Command`s from our parents
-2. Iterate over the list...
-   - Update `NameMap` with any new `Command`s (tracked by the `std::set<InternalActionID>`)
-
-Nested commands will be saved to their own map since they do not have an `InternalActionID`.
-- During `ActionMap`'s population, we must ensure to resolve any conflicts immediately. This means that any new `Command`s that generate a name conflicting with a nested command will take priority (and we'll remove the nested command from its own map). Conversely, if a new nested command conflicts with an existing standard `Command`, we can ignore it because our generation of `NameMap` will handle it.
-- When populating `NameMap`, we must first add all of the standard `Command`s. To ensure layering is accomplished correctly, we will need to start from the top-most parent and update `NameMap`. As we go down the inheritance tree, any conflicts are resolved by prioritizing the current layer (the child). This ensures that the current layer takes priority.
-- After adding all of the standard `Command`s to the `NameMap`, we can then register all of the nested commands. Since nested commands have no identifier other than a name, we cannot use the `InternalActionID` heuristic. However, as mentioned earlier, we are updating our internal nested command map as we add new actions. So when we are generating the name map, we can assume that all of these nested commands now have priority. Thus, we simply add all of these nested commands to the name map. Any conflicts are resolved in favor of th nested command.
-
-### Modifying Actions
-
-There are several ways a command can be modified:
-- change/remove the key chord
-- change the name
-- change the icon
-- change the action
-
-It is important that these modifications are done through `ActionMap` instead of `Command`.
- This is to ensure that the `ActionMap` is always aligned with `Command`'s values. `Command` should only expose getters in the projected type to enforce this. Thus, we can add the following functions to `ActionMap`:
-
- ```c++
- runtimeclass ActionMap
-{
-    void SetKeyChord(Command cmd, KeyChord keys);
-    void SetName(Command cmd, String name);
-    void SetIcon(Command cmd, String iconPath);
-    void SetAction(Command cmd, ShortcutAction action, IActionArgs actionArgs);
-}
- ```
-
-`SetKeyChord` will need to make sure to modify the `_KeyMap` and the provided `Command`.
- If the new key chord was already taken, we also need to update the conflicting `Command`
- and remove its key chord.
-
-`SetName` will need to make sure to modify the `Command` in `_ActionMap` and regenerate `NameMap`.
-
-`SetIcon` will only need to modify the provided `Command`. We can choose to not expose this in the `ActionMap`, but doing so makes the API consistent.
-
-`SetAction` will need to begin by updating the provided `Command`'s `ActionAndArgs`.
- If the generated name is being used, the name will need to be updated. `_ActionMap` will need to be updated with a new `InternalActionID` for the new action. This is a major operation and so all views exposed will need to be regenerated.
-
-Regarding [Layering Actions](#layering-actions), if the `Command` does not exist in the current layer,
- but exists in a parent layer, we need to...
- 0. check if it exists
-    - use the hash `InternalActionID` to see if it exists in the current layer
-    - if it doesn't (which is the case we're trying to solve here), call `_GetActionByID(InternalActionID)` to retrieve the `Command` wherever it may be. This helper function simply checks the current layer, if none is found, it recursively checks its parents until a match is found.
- 1. duplicate it with `Command::Copy`
- 2. store the duplicate in the current layer
-    - `ActionMap::AddAction(duplicate)`
- 3. make the modification to the duplicate
-
-This ensures that the change persists post-serialization.
-
-TerminalApp has no reason to ever call these setters. To ensure that relationship, we will introduce an `IActionMapView` interface that will only expose `ActionMap` query functions. Conversely, `ActionMap` will be exposed to the TerminalSettingsEditor to allow for modifications. 
-
-### Unbinding actions
-
-Removing a name is currently omitted from this spec because there
- is no Settings UI use case for it at the moment. This scenario is
- designed for Command Palette customization.
-
-The only kind of unbinding currently in scope is freeing a key chord such that
- no action is executed on that key stroke. To do this, simply `ActionMap::AddAction` a `Command` with...
- - `ActionAndArgs`: `ShortcutAction = Invalid` and `IActionArgs = nullptr`
- - `Keys` being the provided key chord
-
-In explicitly storing an "unbound" action, we are explicitly saying that this key chord
- must be passed through and this string must be removed from the command palette. `AddAction` automatically handles updating the internal state of `ActionMap` and any conflicting `Commands`.
-
-This allows us to output something like this in the JSON:
-
-```js
-{ "command": "unbound", "keys": "ctrl+c" }
-```
-
-### Consolidated Actions
-
-`AddAction` must be a bit smarter when it comes to the following scenario:
-- Given a command that unbinds a key chord: `{ "command": "unbound", "keys": "ctrl+c" }`
-- And... that key chord was set in a parent layer `{ "command": "copy", "keys": "ctrl+c" }`
-- But... the action has another key chord from a parent layer `{ "command": "copy", "keys": "ctrl+shift+c" }`
-
-`_ActionMap` does not contain any information about a parent layer; it only contains actions introduced in the current layer. Thus, in the scenario above, unbinding `ctrl+c` is what is relevant to `_ActionMap`. However, this may cause some complications for `GetKeyChordForAction`. We cannot simply check our internal `_ActionMap`, because the primary key chord in the entry may be incorrect. Again, this is because `_ActionMap` is only aware of what was bound in the current layer.
-
-To get around this issue, we've introduced `_ConsolidatedActions`. In a way, `_ConsolidatedActions` is similar to `_ActionMap`, except that it consolidates the `Command` data into one entry constructed across the current layer and the parent layers. Specifically, in the scenario above, `_ActionMap` will say that `copy` has no key chords. In fact, `_ActionMap` has no reason to have `copy` at all, because it was not introduced in this layer. Conversely, `_ConsolidatedActions` holds `copy` with a `ctrl+shift+c` binding, which is then returned to `GetKeyChordForAction`.
-
-To maintain `_ConsolidatedActions`, any new action added to the Action Map must also update `_ConsolidatedActions`. It is especially important to handle and propagate collisions to `_ConsolidatedActions`.
-
-When querying Action Map for an ID, we should always check in the following order:
-- `_ConsolidatedActions`
-- `_ActionMap`
-- repeat this process for each parent
-
-This is to ensure that we are returning the correct and wholistic view of a `Command` on a query. Rather than acquiring a `Command` constructed in this layer, we receive one that contains all of the data acquired across the entire Action Map and its parents. 
-
-## Future considerations
-
-There are a number of ideas regarding actions that would be fairly trivial to implement given this refactor:
-- [#6899]: Action IDs
-  - As actions grow to become more widespread within Windows Terminal (i.e. dropdown and jumplist integration),
-     a formal ID system would help users reference the same action throughout the app. With the internal
-     ID system introduced earlier, we would simply introduce a new
-     `std:map<string, InternalActionID> _ExternalIDMap` that is updated like the others, and add a `String ID`
-     property to `Action`.
-- [#8100] Source Tracking
-  - Identifying where a setting came from can be very beneficial in the settings model and UI. For example,
-     profile settings now have an `OverrideSource` getter that describes what `Profile` object the setting
-     came from (i.e. base layer, profile generator, etc...). A similar system can be used for `Action` in
-     that we record if the action was last modified in defaults.json or settings.json.
-  - There seems to be no desire for action inheritance (i.e. inheriting the name/key-chord from the parent).
-     So this should be sufficient.

-# Keyboard Selection
-
-## Abstract
-
-This spec describes a new set of non-configurable keybindings that allows the user to update a selection without the use of a mouse or stylus.
-
-## Inspiration
-
-ConHost allows the user to modify a selection using the keyboard. Holding `Shift` allows the user to move the second selection endpoint in accordance with the arrow keys. The selection endpoint updates by one cell per key event, allowing the user to refine the selected region.
-
-Mark mode allows the user to create a selection using only the keyboard, then edit it as mentioned above.
-
-
-## Solution Design
-
-The fundamental solution design for keyboard selection is that the responsibilities between the Terminal Control and Terminal Core must be very distinct. The Terminal Control is responsible for handling user interaction and directing the Terminal Core to update the selection. The Terminal Core will need to update the selection according to the preferences of the Terminal Control.
-
-Relatively recently, TerminalControl was split into `TerminalControl`, `ControlInteractivity`, and `ControlCore`. Changes made to `ControlInteractivity`, `ControlCore`, and below propagate functionality to all consumers, meaning that the WPF terminal would benefit from these changes with no additional work required.
-
-### Fundamental Terminal Control Changes
-
-`ControlCore::TrySendKeyEvent()` is responsible for handling the key events after key bindings are dealt with in `TermControl`. At the time of writing this spec, there are 2 cases handled in this order:
-- Clear the selection (except in a few key scenarios)
-- Send Key Event
-
-The first branch will be updated to _modify_ the selection instead of usually _clearing_ it. This will happen by converting the key event into parameters to forward to `TerminalCore`, which then updates the selection appropriately.
-
-#### Idea: Make keyboard selection a collection of standard keybindings
-One idea is to introduce an `updateSelection` action that conditionally works if a selection is active (similar to the `copy` action). For these key bindings, if there is no selection, the key events are forwarded to the application.
-
-Thanks to Keybinding Args, there would only be 1 new command:
-| Action | Keybinding Args | Description |
-|--|--|--|
-| `updateSelection` |                                                | If a selection exists, moves the last selection endpoint. |
-|                       | `Enum direction { up, down, left, right }` | The direction the selection will be moved in. |
-|                       | `Enum mode { char, word, view, buffer }`   | The context for which to move the selection endpoint to. (defaults to `char`) |
-
-
-By default, the following keybindings will be set:
-```JS
-// Character Selection
-{ "command": {"action": "updateSelection", "direction": "left",  "mode": "char" }, "keys": "shift+left" },
-{ "command": {"action": "updateSelection", "direction": "right", "mode": "char" }, "keys": "shift+right" },
-{ "command": {"action": "updateSelection", "direction": "up",    "mode": "char" }, "keys": "shift+up" },
-{ "command": {"action": "updateSelection", "direction": "down",  "mode": "char" }, "keys": "shift+down" },
-
-// Word Selection
-{ "command": {"action": "updateSelection", "direction": "left",  "mode": "word" }, "keys": "ctrl+shift+left" },
-{ "command": {"action": "updateSelection", "direction": "right", "mode": "word" }, "keys": "ctrl+shift+right" },
-
-// Viewport Selection
-{ "command": {"action": "updateSelection", "direction": "left",  "mode": "view" }, "keys": "shift+home" },
-{ "command": {"action": "updateSelection", "direction": "right", "mode": "view" }, "keys": "shift+end" },
-{ "command": {"action": "updateSelection", "direction": "up",    "mode": "view" }, "keys": "shift+pgup" },
-{ "command": {"action": "updateSelection", "direction": "down",  "mode": "view" }, "keys": "shift+pgdn" },
-
-// Buffer Corner Selection
-{ "command": {"action": "updateSelection", "direction": "up",    "mode": "buffer" }, "keys": "ctrl+shift+home" },
-{ "command": {"action": "updateSelection", "direction": "down",  "mode": "buffer" }, "keys": "ctrl+shift+end" },
-```
-These are in accordance with ConHost's keyboard selection model.
-
-This idea was abandoned due to several reasons:
-1. Keyboard selection should be a standard way to interact with a terminal across all consumers (i.e. WPF control, etc.)
-2. There isn't really another set of key bindings that makes sense for this. We already hardcoded <kbd>ESC</kbd> as a way to clear the selection. This is just an extension of that.
-3. Adding 12 conditionally effective key bindings takes the spot of 12 potential non-conditional key bindings. It would be nice if a different key binding could be set when the selection is not active, but that makes the settings design much more complicated.
-4. 12 new items in the command palette is also pretty excessive.
-5. If proven wrong when this is in WT Preview, we can revisit this and make them customizable then. It's better to add the ability to customize it later than take it away.
-
-#### Idea: Make keyboard selection a simulation of mouse selection
-It may seem that some effort can be saved by making the keyboard selection act as a simulation of mouse selection. There is a union of mouse and keyboard activity that can be represented in a single set of selection motion interfaces that are commanded by the TermControl's Mouse/Keyboard handler and adapted into appropriate motions in the Terminal Core.
-
-However, the mouse handler operates by translating a pixel coordinate on the screen to a text buffer coordinate. This would have to be rewritten and the approach was deemed unworthy.
-
-
-### Fundamental Terminal Core Changes
-
-The Terminal Core will need to expose a `UpdateSelection()` function that is called by the keybinding handler. The following parameters will need to be passed in:
-- `enum SelectionDirection`: the direction that the selection endpoint will attempt to move to. Possible values include `Up`, `Down`, `Left`, and `Right`.
-- `enum SelectionExpansion`: the selection expansion mode that the selection endpoint will adhere to. Possible values include `Char`, `Word`, `View`, `Buffer`.
-
-#### Moving by Cell
-For `SelectionExpansion = Char`, the selection endpoint will be updated according to the buffer's output pattern. For **horizontal movements**, the selection endpoint will attempt to move left or right. If a viewport boundary is hit, the endpoint will wrap appropriately (i.e.: hitting the left boundary moves it to the last cell of the line above it).
-
-For **vertical movements**, the selection endpoint will attempt to move up or down. If a **viewport boundary** is hit and there is a scroll buffer, the endpoint will move and scroll accordingly by a line.
-
-If a **buffer boundary** is hit, the endpoint will not move. In this case, however, the event will still be considered handled.
-
-**NOTE**: An important thing to handle properly in all cases is wide glyphs. The user should not be allowed to select a portion of a wide glyph; it should be all or none of it. When calling `_ExpandWideGlyphSelection` functions, the result must be saved to the endpoint.
-
-#### Moving by Word
-For `SelectionExpansion = Word`, the selection endpoint will also be updated according to the buffer's output pattern, as above. However, the selection will be updated in accordance with "chunk selection" (performing a double-click and dragging the mouse to expand the selection). For **horizontal movements**, the selection endpoint will be updated according to the `_ExpandDoubleClickSelection` functions. The result must be saved to the endpoint. As before, if a boundary is hit, the endpoint will wrap appropriately. See [Future Considerations](#FutureConsiderations) for how this will interact with line wrapping.
-
-For **vertical movements**, the movement is a little more complicated than before. The selection will still respond to buffer and viewport boundaries as before. If the user is trying to move up, the selection endpoint will attempt to move up by one line, then selection will be expanded leftwards. Alternatively, if the user is trying to move down, the selection endpoint will attempt to move down by one line, then the selection will be expanded rightwards.
-
-#### Moving by Viewport
-For `SelectionExpansion = View`, the selection endpoint will be updated according to the viewport's height. Horizontal movements will be updated according to the viewport's width, thus resulting in the endpoint being moved to the left/right boundary of the viewport.
-
-#### Moving by Buffer
-
-For `SelectionExpansion = Buffer`, the selection endpoint will be moved to the beginning or end of all the text within the buffer. If moving up or left, set the position to 0,0 (the origin of the buffer). If moving down or right, set the position to the last character in the buffer.
-
-
-**NOTE**: In all cases, horizontal movements attempting to move past the left/right viewport boundaries result in a wrap. Vertical movements attempting to move past the top/bottom viewport boundaries will scroll such that the selection is at the edge of the screen. Vertical movements attempting to move past the top/bottom buffer boundaries will be clamped to be within buffer boundaries.
-
-Every combination of the `SelectionDirection` and `SelectionExpansion` will map to a keybinding. These pairings are shown below in the UI/UX Design --> Keybindings section.
-
-**NOTE**: If `copyOnSelect` is enabled, we need to make sure we **DO NOT** update the clipboard on every change in selection. The user must explicitly choose to copy the selected text from the buffer.
-
-
-## UI/UX Design
-
-### Key Bindings
-
-There will only be 1 new command that needs to be added:
-| Action | Keybinding Args | Description |
-|--|--|--|
-| `selectAll`  | | Select the entire text buffer.
-
-By default, the following key binding will be set:
-```JS
-{ "command": "selectAll", "keys": "ctrl+shift+a" },
-```
-
-## Capabilities
-
-### Accessibility
-
-Using the keyboard is generally a more accessible experience than using the mouse. Being able to modify a selection by using the keyboard is a good first step towards making selecting text more accessible.
-
-### Security
-
-N/A
-
-### Reliability
-
-With regards to the Terminal Core, the newly introduced code should rely on already existing and tested code. Thus no crash-related bugs are expected.
-
-With regards to Terminal Control and the settings model, crash-related bugs are not expected. However, ensuring that the selection is updated and cleared in general use-case scenarios must be ensured.
-
-### Compatibility
-
-N/A
-
-### Performance, Power, and Efficiency
-
-## Potential Issues
-
-### Grapheme Clusters
-When grapheme cluster support is inevitably added to the Text Buffer, moving by "cell" is expected to move by "character" or "cluster". This is similar to how wide glyphs are handled today. Either all of it is selected, or none of it.
-
-## Future considerations
-
-### Word Selection Wrap
-At the time of writing this spec, expanding or moving by word is interrupted by the beginning or end of the line, regardless of the wrap flag being set. In the future, selection and the accessibility models will respect the wrap flag on the text buffer.
-
-## Mark Mode
-
-This functionality will be expanded to create a feature similar to Mark Mode. This will allow a user to create a selection using only the keyboard.

 2. Take the parts you want, but leave most of it behind since it's HUGE and will bloat the repo to take it all.  At the time of this writing, we only use small_vector.hpp and its dependencies as a header-only library.
 3. Validate that the license in the root of the repository didn't change and update it if so. It is sitting in a version-specific subdirectory below this readme. 
    If it changed dramatically, ensure that it is still compatible with our license scheme. Also update the NOTICE file in the root of our repository to declare the third-party usage.
