* '''Q,A,O,P,SPACE''' - (Q up, A down, O left, P right, SPACE fire) This is a good solution, and it's a sort of standard (used by many games). It is best for english QWERTY keyboards, on french AZERTY it'd be A-Q-O-P (but because the decoding of the keys is done in software, normally by the OS, the bits in the keyboard matrix are actually the same).
