bind
The bind command is used to set certain keys to certain functions. Most keys can be binded using the client options menu. However, certain commands not in that menu can be set using this console command.
Ex. To set the F10 key to close Odamex on button press the console command bind F10 quit would be used. This tells Odamex to run the command 'quit' through the console when the F10 key is pressed.
