TRANSITION : 2 choices, DOWN = when you press a key, UP = when you release the pressure on the key, usually you won't change that
MODIFIER : used to execute the action in two times, like for example CTRL + KEY
WARNING : AZERTY users, all keys are in QWERTY, for example if you put A you'll have to press Q in game
