Originally created by @atifraza on GitHub (Sep 7, 2020).

Environment

Windows build number: 19041.450
Windows Terminal version (if applicable): 1.2.2381.0

Any other software?
WSL: 2
Distro: Ubuntu 20.04

Steps to reproduce

Keyboard layout: US (QWERTY) or US-International (QWERTY)

Terminal key bindings: default

"altGrAliasing": false

Expected behavior

Tmux in WSL has pane switching keybindings set to Ctrl+Alt+[arrow keys].
Before the update to 1.2.2381.0, the keybindings were working and switching panes in a window was possible with these keybindings.
Pressing Ctrl+Alt+[arrow keys] should be passed to the WSL instance so that tmux keybindings are triggered.

Actual behavior

After the update, the keybindings don't work anymore.
The "altGrAliasing": false setting has also been tested, and the checks as per pull request 7400 show the correct/expected characters.

Example:

$  showkey -a

Press any keys - Ctrl-D will terminate this program
# Pressed AltGr+Q

@dihmandrake commented on GitHub (Sep 15, 2020):

Edit: The issue has fixed itself for me as well. The only installed update on my machine is a new version of the WSL 2, but I doubt that had anything to do with this issue. Neither Windows or the Terminal was updated since then and I haven't changed the settings since the report of this issue. If it occours again I will update this comment.

I am seem to have the same issue. None of the shortcuts assigned to ctrl+alt+XY seem to work anymore. I am quite sure it used to work last week and it therefore might an issue with Windows, but I cannot guarantee that.

For anyone that might stumble upon this issue: I finally figured out what caused the problem on my machine. Intel Graphics Command Center. Even though Hotkeys are disabled they sometimes block the keyboard combinations with crtl+alt in applications. Enabling and disabling the combinations in the Intel Graphics Command Center solves the issue for me. Still, it appears that the Intel implementation contains some bugs and they block combinations after a while (might be reboot releated).

@Edstar3000 first off, this thread is like two years old and totally unrelated to shift+arrows selection. You're probably interested in "Mark mode", which I believe shipped in 1.15 builds.

Damn this was fast.
Thanks a lot!
However, I still cannot mark words by using shift + arrow keys as it is
easily done with Linux.
On the thread stated above I could not find a solution either, am I stupid?

Mit freundlichen Grüßen
