[PC] COD MW2 Key Bindings!

For almost all FPS games, I think the best layout is:
WASD: move
left click: shoot
right click: aim
R: reload
scroll wheel: switch weapon
space: jump
shift: sprint
C: crouch/lie down
A: special grenade
E: grenade
2468 (on the numpad): for special weapons like claymore, C4...

I did this from memory for COD6 because it's been a while since I uninstalled it.
After that, you'll find your personal configuration as you play according to your reactions or comfort with the game. Hope this gives you some ideas.

Thank you.
