Do you mean on which button what does? I can help you...
Left or Right arrow: walk left or right
Up arrow: hoist, get grenade, drink Brew
Down arrow: crouch (stand up with Up arrow)
SHIFT + Left or Right arrow: run left or right
SPACE: hop
CTRL: pull levers etc.
X: fart, crouch from running
Z: shoot with Sligs
0: chant
1: Hello
2: Follow me
3: Wait
4: Work
5: Anger & slap
6: All'o'ya
7: Sympathy
8: Stop it!
I think that's all. There are combinations like runjump and stuff, but I think I need not explain it.
Hope this helped you!
