ctrl+alt+<num> behaves differently from altGr+<num>

[kallekankaanpaa]

Description

I can't insert special characters such as @ with ctrl+alt+2, using altGr+2 works normally.
The only combinations that work are ctrl+alt+0 and ctrl+alt+?. I found this issue concerning the latter one.

Steps to reproduce

1. Use ISO Nordic layout
2. Open Windows Terminal
3. Press ctrl+alt+2

Expected behaviour

Inputs @ to terminal

Actual behaviour

Inputs nothing to terminal

Environment

Microsoft Windows [Version 10.0.19042.928]
Windows Terminal: Version: 1.7.1033.0
Keyboard Layout:  ISO Nordic

Hey, I have the same problem, how did you fix it?

@Teiem : To solve this you can disable the terminal shortcuts. Modify your settings.json such that the action array contains the following:

"actions":
[
    { "command": null, "keys": "ctrl+alt+1" },
    { "command": null, "keys": "ctrl+alt+2" },
    { "command": null, "keys": "ctrl+alt+3" },
    { "command": null, "keys": "ctrl+alt+4" },
    { "command": null, "keys": "ctrl+alt+5" },
    { "command": null, "keys": "ctrl+alt+6" },
    { "command": null, "keys": "ctrl+alt+7" },
    { "command": null, "keys": "ctrl+alt+8" },
    { "command": null, "keys": "ctrl+alt+9" }
]

Nice work-around :-)

I see the same problem typing CTRL+ALT+@ | £ | $ | { | [ | ] | } (on Nordic keyboard layout).

To add this work-around to settings.json with Powershell:

$file = "$env:localappdata\Microsoft\Windows Terminal\settings.json";
copy $file $file".old"; 
$json = Get-Content -Path $file -Raw | ConvertFrom-Json
$json.actions += [PSCustomObject]@{command="closePane"; keys="ctrl+f4"}
$json.actions += [PSCustomObject]@{command=$null; keys="ctrl+alt+["}
$json.actions += [PSCustomObject]@{command=$null; keys="ctrl+alt+]"}
$json.actions += [PSCustomObject]@{command=$null; keys="ctrl+alt+{"}
$json.actions += [PSCustomObject]@{command=$null; keys="ctrl+alt+}"}
$json.actions += [PSCustomObject]@{command=$null; keys="ctrl+alt+@"}
$json.actions += [PSCustomObject]@{command=$null; keys="ctrl+alt+£"}
$json.actions += [PSCustomObject]@{command=$null; keys="ctrl+alt+$"}
$json.actions += [PSCustomObject]@{command=$null; keys="ctrl+alt+e"}
$json.profiles.list += [PSCustomObject]@{name="Powershell 7"; guid="{"+(new-guid).Guid+"}"; commandline="""C:\\Program Files\\PowerShell\\7\\pwsh.exe"" -WorkingDirectory c:\\temp"; font=[PSCustomObject]@{size = 10}}
Write-Output $json | ConvertTo-Json -Depth 10 | Out-File $file -Encoding Utf8 

(Will also add the de-facto shortcut for closing current tap: CTRL+F4 and add a profile for PS7):

Strange I only see this issue in Powershell terminals (both legacy and PS7), not in CMD terminal.
