i think i'll bind my melee to V, in cod 5 (i think, the original one w/ zombies) had it defaulted to V and i just became adjusted to that and i switch it to that for every game!
i bet either F or G is for grenade
E's probably use
fire = left click
aim/sights = right click
quick weapon switch = scroll
primary/2ndary weapon = 1/2
abilities 1-3 = probably 3-5
THESE are what i'm expecting :S and the melee key-binding is what i'll make personally lol.
