@Pantherina@sputge I think the F[number] stuff gets directly passed to the OS, just the [Fn] stuff (those extra features to change the display brightness, volume, etc.) is managed by the Keyboard (?) or BIOS
Hm, so on my Thinkpad I had “sticky keys” which made the keys do the Fn function instead of the normal one, I had to change that in BIOS. But in KDE I can still assign F2=volUp (which is an OS feature and not the actually assigned Fn+F2 button)
