It would be nice to have a diagram showing the used and unused keys of the keyboard, so that it's easier to set keybinds. The game, much like Arma 3, has a lot of keybinds. Players will additionally use services like Teamspeak on top of the in game controls. So it would be useful to know which keys are available on the keyboard, or at least which keys are unbound.

Something like this one but maybe nicer and dynamic.
