Description Jin Liu 2024-01-15 01:27:11 UTC

SUMMARY
It only works in the shortcut KCM.

STEPS TO REPRODUCE
1. Right click on Kickoff, Configure, Shortcut.
2. Press the button.
3. Press `Meta`.

OBSERVED RESULT
`Meta` appears on the button, then immediately disappears.

EXPECTED RESULT
`Meta` is set as the shortcut after a second, just like in the shortcut KCM.

the meta shortcut should open kickoff no matter what shortcut is set, but yeah, the ui is not clear at all

I see. So the actual problem is:
1. The user can set modifier-only shortcuts like 'Meta', 'Control', 'Shift', etc., in the shortcuts KCM, (e.g. I can bind kickoff to `shift`) but not in applet configure dialogs.
2. Setting 'Meta' as the shortcut in the KCM won't work, because it's overridden by either this default, or `[ModifierOnlyShortcuts]` in `kwinrc`.

Actually we decided for Plasma 5.27 to explicitly move away from this in the future when we made it possible to use modifiers alone as shortcuts. ...But then we never ported Kickoff to use the feature, and we never deprecated the old ModifierOnlyShortcut feature in KWin.

We need to finish doing that, make it possible for applet config windows to use modifier-only shortcuts, and then set a modifier-only Meta key shortcut for Kickoff.

The issue here appears to be that `KeySequenceItem`--which lives in KDeclarative--does not work for this. Moving the bug report there.
