"switch to alternate"

[Rhino05]

I have a problem, in the FA servers, i cant use the "switch to alternate" (the option to put the granade in the rifle or to use the telescopic sight in the sniper), i can see that others players can use it, but in my case, i cant change that thing in the controls, i try put the "mouse 3" in that option, but only appear "???"
do you understand me?, in others servers i can use that option, only in the FA i cant use it

 

ps: sorry if my english is not good jajajajaja

If it's in Jaymod, doe ESC, Jaymod, Misc., set desired key under Alternate.

Or use ET console(Press ~) /bind mouse3 +attack2 [Press Enter]

 

Throwknife can be wicked binded to mousewheel!
