Hi there, maybe I am mistaken, but it seems the Ctrl+Z option to undo painting is "hardcoded" to a certain keyboard key, which means, for me on a german keyboard it's actually using ctrl+y. Is there a way to change that key? And if not, would it be possible to implement a config option or anything like that?

Thanks in advance ^^

Can you tell me which version you are playing? Also could you describe the problem a bit more clearly? I tested on 1.20.1 with the windows onscreen keyboard set to german, and on that layout there is Y in place of Z at the bottom left corner, and pressing ctrl (strg) + Y acted as undo, which is the desirable outcome because it is the same physical motion. How does it work in your case exactly?
