Do you have an alias file loaded? Alt-R > Aliases tab. If you don't have one loaded that has commands for /voice and /op, then you aren't going to be able to do that.

Just create a new file in the aliases tab with the following:

Code:
voice { if ($chan) { mode $chan +v $1- } }
op { if ($chan) { mode $chan +o $1- } }


That doesn't make sure you selected valid nicks, but as long as you choose valid nicks, it should work fine.
