Dude on LJ had 1000 instances he needed to swap from Symbol A to Symbol B. Didn’t want to do it manually, so I wrote this command for him. Maybe you’ll find a use for it too.
You select a frame, and it’ll swap all instances to use a different symbol that you specify. Instead of clicking the instance on the stage, clicking swap, and repeating for each symbol, this just does it en-masse at light speed.
