Description Mike Eichler 2019-10-01 19:10:48 UTC

SUMMARY
Changing keys around prevents some Kwin shortcuts from working.

Note - I use Meta and Super interchangeably here. They both refer to the key left of Alt, where many keyboards have a custom logo.

What I would like to achieve:
1) Swap left alt and left control and escape and caps lock
2) Use super+tab to switch windows
3) Use ctrl+alt+arrow to move to different desktops
4) Use shift+ctrl+alt+arrow to move windows to different desktops

STEPS TO REPRODUCE
1. Open Settings > Shortcuts > Global Shortcuts > KWin
2. Set Switch One Desktop Down to Ctrl+Alt+Down, set analogous shortcuts for up, left and right
3. Set Window One Desktop Down to Ctrl+Alt+Shift+Down, set analogous shortcuts for up, left and right
4. Set Walk Through Windows to Meta+Tab
5. Set Walk Through Windows (Reverse) to Meta+Shift+Tab
6. Hit Apply
Confirm that the shortcuts work as intended. If not, log out and log in. The shortcuts should now work.
7. Open Settings > Hardware > Input Devices > Keyboard > Advanced tab
8. Check Configure Keyboard Options
9. Select Caps Lock behaviour > Swap ESC and Caps Lock
10. Select Ctrl position > Swap Left Alt with Left Ctrl
Confirm that Esc and Caps Lock, and Left Ctrl and Left Alt are now swapped.

OBSERVED RESULT
After step 10, Super+Tab no longer works. Alt+Tab (Alt now being on the Ctrl key) run the window switcher exactly ones.
Trying to repeat steps 1 through to 6 doesn't work:
* Pressing Meta+Tab on the Walk Through Windows shortcut selector, moves the focus to a different UI element
* Trying to reset the shortcuts from steps from steps 2 and 3 has no effect.

EXPECTED RESULT
Pressing Esc changes the caps lock
Pressing Caps Lock functions as Escape
Left Alt and Left Control are swapped
Meta+Tab switches windows, Meta+Shift+Tabs switches windows in reverse
Control+Alt+Arrows move to different desktops
Control+Alt+Shift+Arrows move windows to different desktops
