Thank you, much appreciated! I always wondered if the decision to only have one fire button in Q3A was based off its compatibility with Mac OS, and thus a lack of a second mouse button. Other FPS at the time (e.g. Unreal Tournament, Half-Life) usually had a secondary fire button to allow for alternate weapon functions (e.g. grenade launcher on SMG, zoom on sniper rifle/crossbow, etc), which was mapped to the right mouse button.
