Version: unspecified OS: Linux there is no possibility to change the shortcut for undo and redo inside krita. one has to change it in system settings. some kde programs make it possible to change this shortcut, but others don't. it's possible in kwrite and it's not possible in kdevelop. i don't know, what's the correct behaviour, but we will have many non-kde users, so it's probably better to have the ability to change it.
