Ah, I like my controlls just how they are, and I have no discomfort with them.

They are kind of like the WASD controlls of 3D shooters in a way, because the keys I use are around that area.

Arrow keys are all at their default values, of course.

Shift=Run
Z=Shoot
X=Jump
C=Change weapon

It works well for me, because they are all in a row, without my hand being in an awkward position, however I'd have to change the keys if I was to have someone else at the keyboard with me on multiplayer. It is only set up for one person at the keyboard.

Oh yeah, and if I don't know I am in chat mode, and try to jump, I may end up typing XXX by mistake
