well here's your problem.
Go ahead and bind EVERYTHING. And nothing past 6. 1-6 is all your hand can reach feasibly, maybe 7 if you have HUGE hands. Start binding q, e, r, t, f, g, z, x, c, v, b and all shift/control modifiers. and use your mouse to turn.
The only things you should ever have unbound, and some bind them anyway, is a your speeder, maybe your class buff, maybe sprint.
