hey, I am creating a game in AS3, what I want to do is when the player presses a key combo for example Left Key+Jump & Kick key, the character performs a move e.g like a kamehameha... I also want to execute the action correctly for example the character doesn't perform a left jump kick as its the same key

i was thinking of using a array, to handle the key combo...is there any other way of doing this, more efficient or more performance?
