Cod2 fonction

hello everybody

Someone can tell me what is the cod2 fonctions to press?
i know only:
attackbuttonpressed()
meleebuttonpressed()
usebuttonpressed()

or it's possible to create own buttons?
example: press [u] to use the bubble!
if yes, how? :)
because on somethings, i must do disableweapon/enableweapon like pickup command and it's not good.

i think it's possible because on some servers, they use the mouse but the button between click left and click right.
