As wiki says, These default controls can be modified with /bind.
T - Chat
Tab - Show scoreboard
` - Show console
F4 - Toggle spawnscreen
F5 - Enable/disable chatbox
F6 - Show network statistics
F12 - Take a screenshot
Spawn Screen
Left/Right - Select class
Control - Spawn
I think that, any non default data should be saved in
Config.conf file.
But nobody knows ( except Developers or Testers) correct syntax for /bind command
