Up arrow does not work STEPS TO REPRODUCE 1. Log into KDE 2. Try to use up arrow in any app OBSERVED RESULT Nothing happens when pressing the UP arrow EXPECTED RESULT The cursor should move upwards SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.24.3 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION All other keys work as far as I can see, even up on numpad, the key does work in Windows and in textmode, that is if I press CTRL+ALT+F2, so even if KDE is runnin in another screen.
Just found out that SHIFT+UP works just fine :-)
Found the problem. After changing window switcher the Walk through Windows of current application was set to up! Weird..But typing "up" in shortcuts reviled this. I changed it to META+CTRL+SHIFT+Up and it now works
