I made this in the 1.02 days, when yellow wasn't USELESS (yet)
. It allows you to execute the red backswing while in yellow stance, and brings you back to yellow once it finishes.
bind MOUSE3 "saberattackcycle 3;wait;wait;wait;wait;+back;+attack;wait;wait;-back;-attack;saberattackcycle 1"
Looks simple, but it took me one hell of a lot of trial and error.
