The file just presets some key sequences in Teamspeak to do things like change channels and to broadcast to all channels (this function should be primarily used by the person filling the Flight Lead seat for coord between flights) whilst in game.
Now while I have designed the key binds file to use specific keys and key sequences, that doesn't mean that the selected keys and sequences are set in stone :). If anyone wants to change any or all of them its a fairly easy procedure and if you need help doing this it can be discussed during planning online before we start flying.
Hope that helps ....
Cheers
