So, this is my gaming config. It's maybe not as good as some pro configs but I like it :D You have there
4 filmtweaks, they are binded on f5-f8. On f10 you've got light changing, so you can edit it :D But u have to 
turn them on by B52 (if not wrong :DD)
1-4 are class, Assault, Specops, Sniper and Demolitions.
I am now using lean on Q and E, so if you want, edit it :) Lean to right is on V. Lean to left is on Z
E is for activate (plant, pickup weapons) and Q for smoke
Knife is on X
On mouse u have switching by wheel and on one of my side buttons u have double switch bind :)
Hope you'll like it :)

PS: Sry for my bad english :D
