lol this is going to be funny..

Here's an example key bindings list for CSS for me (edited the order for better logic when reading and only listed the essential keys I share between all FPS games):

bind "a" "+moveleft"
bind "MOUSE1" "+forward"
bind "MOUSE2" "+back"
bind "s" "+moveright"
bind "d" "-speed" < walk / run, also used for sprint in games like BL2
bind c "+duck"
bind "SPACE" "+jump"
bind "CTRL" "+attack"
bind "SHIFT" "+attack2" < sniper zoom etc
bind "x" "+use"
bind "z" "+reload"
bind "g" "drop" < drop weapon, sometimes use q depending on the game
bind "r" "+voicerecord"
bind "t" "messagemode2" < team chat
bind "y" "messagemode" < all chat
bind "BACKSPACE" "chooseteam"
bind "MWHEELDOWN" "invprev"
bind "MWHEELUP" "invnext"

I use this setup for all FPSes I play, and some TPSes also, or games like Prince of Persia. So, mouse keys are move forward and back, A+S for strafing, D for walk, C for crouch, Z for reload, X for use key, SPACE for jump. Shoot with Ctrl, and secondary fire on SHIFT. Seems very strange, but try putting your fingers on the keyboard like that. Hit Ctrl with your pinky finger (also used for SHIFT so secondary fire / sniper zoom etc), ring finger and middle finger on A+S (also using ring finger for Z), using your index finger for C and X, thumb for SPACE. If you tilt your keyboard with the left side slightly further away from you, you get a pretty natural, relaxed hand position and you have very little space to move with your fingers.

YES I KNOW I AM WEIRD, HEARD IT ALL BEFORE. ;D :P

WASD, but now that I think about it and try it out, ESDF works just as fine and mabye even a bit better.

WASD

I don't move, I sit on my ass im my chair

WASD ofc

WASD

8 4 5 6

Numpad 8,5,4,6 for forward,back,left, right. Numpad 0 to jump, Numpad enter to sprint, numpad del for reload, right arrow for Hold to ADS, numpad + to melee, and various other actions bout to keys in the numpad region

moving is for suckers, camping is for the best.

WASD to move and arrow keys to aim, of course

WASD

WSADSwag Jk that ruined it. Now I make you all use arrow keys.

I have small hands, when I tried ESDF I couldn't comfortably reach my shift key.

Arrows. More than 10 years on-line. Kids with WASD crying when I joining server.

WASD

wasd because I usually don't change controls off the default

QWOP! oh wait, didn't read the whole question...

i use mouse and w

I don't move while playing games, I am just sitting on my chair -.-

I got a moves like Jagger.

Sometimes I move forward, and sometimes I move back. Sometime I run and sometimes I walk. Sometimes when I'm feeling crazy and wild I move in prone.

Use WASD only

DSAW. + POTATO. = LOVE.

WASD but in case the game is a comfortable FPS like Borderlands or Spec Ops i prefer gamepad
