well you DO have the ALT + [key] commandability. Â If you really don't think that's enough then i dunno. Â Frankly, if you don't have your w, a, s, d (and keys around those) already functioned with something then that would be a much better solution since pressing ALT + s is much faster than having to search for the k key. Â However a bind command for alt + [key] would be useful.
Also:
/unbind [letter] - restores that letter to its original taunt/command.
/unbind all - unbinds all custom keys to their original taunts/commands.
