It is useful for developing and quality assurance , but can also be used to access cheats . To access the console , use the grave accent key ( ` ) while in - game ( Unpaused ) . The grave accent key shifts to tilde ( ~ ) on US keyboards , and the not symbol ( ¬ ) on UK keyboards . Other keyboard layouts will differ , but the key is usually to the left of 1 , and just under the Escape key ( Esc ) . The key is the top left key under escape , on non - US keyboards .
