You can bind ingame console commands that you would normally use in the chatbook, such as say, to a specific key.

Press "Esc" and click "Settings." Click "Controls" if you just want to change the default keybinds. Press the action you wish to bind to another key. Press the new key to set it. Close this panel when you finish.
