Description 80p3fy75dc 2021-03-26 18:13:36 UTC
STEPS TO REPRODUCE

Tested with English US and French keymaps 
1. Go to System Settings > Shortcuts
2. Try to assign say "Meta+Shift+1" for "Window to Desktop 1" action


OBSERVED RESULT
As you press the keys to define the shortcut, "Meta" and "Shift" appear in the box with the wheel, but as soon as you press "1", the shortcut ends up being "Meta+!". It seems that "Shift" key cannot be used in combination with another key which has two variants. Indeed, "Meta+Shift+<any_letter>" or "Meta+Shift+* (the * key being on the numpad and not having any variant) work just fine. But "Meta+Shift+7" will lead to "Meta+&" and so on.

"Shift+<key>" alone without Meta gives mixed results as well: "Shift+F10" or "Shift+Down" are accepted but other combinations such as "Shift+!", "Shift+" or "Shift+4" aren't.

EXPECTED RESULT

I should be able to assign "Shift+<any_key> or "Meta+Shift+<any_key>" to an action.

Could you check if it differs on Wayland?

I've just tried on Wayland and it doesn't make any difference unfortunately. Same behavior than on X11.

Any update?
Comment 4 Andrey 2021-10-04 11:39:01 UTC
Could you try to do some investigation and find related issues here or for Qt?
I think I saw something related with Shift modifier for shortcuts..

It would help to push it forward.
