Files uses hardware keycodes to identify keyboard events for 'C', 'V' and 'X' so Ctrl-C, Ctrl-V and Ctrl-X should work with different keymaps (assuming the modifier keys work normally). However 'N' is identified by the event keyval as normal so Ctrl-Shift-N may not work. This key could also be identified by hardware keycode.
