Firstly, congrats on the launch!

In Scripts/Core/KeyCode.c, we have the Function keys F1-F12, however, function keys F13-24 are missing. Also, mouse "keys" Mouse4 and Mouse5 are missing. These keys are helpful since many (myself included) bind these keys to buttons on the side of their mice. Some mice can come with up to 12-15 keys on the side, and a game with as many controls as Arma would benefit. I'd also like to use these keys for modding purposes.

Considering KeyCode contains keycodes for the media selection buttons I would like to see as many keys as possible.
