How do you move when you're playing a FPS?

WASD because I don't need to type. Also the thumb is right in the middle of the space bar while the pinky can go from Ctrl to shift.

wasd or as someone said below, gamepad depending on the game. I used gamepad for Specops and Tomb Raider but for BF3 I use K/m

I use QMOS

I use PLÆØ because I'm left handed

I use the arrow keys, bind anything else to my 13 button mouse.

I use QWOP

WASD & Arrow Keys

I frequently sprain my right wrist, so when that happens I use my mouse with my left hand and arrow keys with my right, that way I can still game properly

WASD and... move like Jagger

WASD all the wayyyyy!

I actually played cod4 with the arrow keys long time ago. Damn I was good xD.
WASD is the way to go now!
