Description Akseli Lahtinen 2024-01-18 09:29:31 UTC 
SUMMARY

In my kdesrc-built Plasma 6 setup, I have rebound Meta+tab to switch between windows, and Alt+tab to switch between virtual desktops.

Meta+tab works, but alt+tab is seemingly not recognised: Apps tend to think im just pressing alt and tab, and the combo does not do anything.

STEPS TO REPRODUCE
1. Set shortcut for window switching to meta+tab
2. Set shortcut for switching between virtual desktops to alt+tab

OBSERVED RESULT
Alt+tab no worky

EXPECTED RESULT
Alt+tab would switch between virtual desktops

Comment 1 duha.bugs 2024-01-18 18:26:11 UTC 
Which keyboard shortcut did you assign to ALT+TAB?

Works for me on git master if I set it to "Switch to next Desktop".

Possibly conflicting shortcuts?
Comment 2 Akseli Lahtinen 2024-01-18 19:27:02 UTC 
I set it to "walk through desktops"

Does not work with Switch to next Desktop either, though
Comment 3 Nate Graham 2024-01-18 20:52:31 UTC 
Which exact actions have you bound Alt+Tab (and presumably, Alt+Shift+Tab for reverse) to? I see several that could qualify.
Comment 4 Akseli Lahtinen 2024-01-18 23:51:54 UTC 
Walk through desktops: alt+tab

Walk through desktops (reverse): alt+shift+tab
Comment 5 Akseli Lahtinen 2024-01-18 23:53:05 UTC 
For some reason now the following work:

Switch to next desktop: alt+tab

Switch to previous desktop: alt+shift+tab
Comment 6 Nicolas Fella 2024-01-19 14:56:36 UTC 
I think this was intentionally dropped in https://invent.kde.org/plasma/kwin/-/merge_requests/3871

It seems there is a bug where kglobalaccel doesn't "forget" the non-existent action

> It seems there is a bug where kglobalaccel doesn't "forget" the non-existent action

Should we add a kconf_update script or something to drop these actions?
