hotkeys do not respect the selected OS input language

[KrabCode]

for example Ctrl + Z and Ctrl + Y (undo / redo) are flipped when the keyboard is in cs/cz, but work as expected in en/gb
the program always reacts to what is assumed to be english keys regardless of the selected keyboard language

[KrabCode]

this should probably be solved on some global java level, since we need it to work on all platforms
