Description Natalie Clarius 2023-02-17 23:05:19 UTC 
SUMMARY
***
When setting only the meta key as a shortcut for anything, any key combination involving the meta key will also trigger the modifier-only shortcut in addition to the actual key combination.
***

STEPS TO REPRODUCE
1. Assign just the meta key to any action (call it A)
2. Assign meta + some other key to any action (call it B)
3. Trigger the key combination for B

OBSERVED RESULT
A and B happen

EXPECTED RESULT
Only B happens

I guess then it's a matter for these shortcuts to be triggered on release. At the moment we do it on press and we do not yet know whether there will be other keys pressed afterwards.

It's the other side of the coin of https://bugs.kde.org/show_bug.cgi?id=465867
Comment 3 Nate Graham 2023-02-22 02:03:05 UTC 
I think it's time to remove the modifier only shortcut concept from KWin, now that it's redundant because we can trigger modifier-only shortcuts using KGlobalAccel.
Comment 4 Vlad Zahorodnii 2026-01-22 11:59:30 UTC 
It works as expected for me. Also kglobalacceld has code to reset its state if it sees a key other than a modifier. If you are still able to reproduce the issue, reopen the issue and perhaps move the bug report to the corresponding product (kwin no longer manages modifier only shortcuts, it only feeds kglobalcceld with key events).
