Key binding

Key binding is the act of assigning keys or buttons to various controls, rather than using the default layout. In many Battlefield games, the player can change key bindings in the main menu.

Battlefield 3
With the Battlelog system in place, the player cannot currently change controls unless they are in an active server. Also, controls cannot be changed mid-game.

To access key bindings, one must enter an empty server, press ESC to access the game menu, and find the menu option. The player must keep watch for other players that enter the server, or the game may start without their attention.
