Installed with zkl, hotkeys in other mods do not work (impossible to quit game!)

Not on my own computer so not 100% sure:
It seems when installing zkl and using it to play other mods (BA, XTA) some of the engine-default hotkeys do not work.
F1 to F4 work but for example "t = track unit" does not work.
Worst is that "ESC / shift+ESC = quit game" does not work.
This means players can only exit the game by taskmanager, since noone knows about /quit textcommand.

This was an unfortunate bug due to this: http://springrts.com/mantis/view.php?id=2944

For a long time the engine menu would completely break games so it was effectively removed.

I think there's some widget that unbind "quit" but I'm not sure where is it.

But since @Carrepairer added "quit" to the zkkey I think it will override all those unbinds and rebind it to anything that is written in zkkey.
