bind mouse2 +attack2
I've always been bugged by the Ubersaw taunting when you right click. Why??
So, I made right click do something more useful. When you hold your right mouse button down, you switch to the Medi Gun and pop an ÜberCharge. Also, it drops the Intelligence or the PASS Time JACK so you can Über in the first place.
Furthermore, if you accidentally right click the Über dosen't happen instantly, so you have time to think about the horrendous crime you've committed.
