I found a post on multiboxingdotcom through google (I don't go to the site, I just found it funny that google popped it up).

The post was made by Ualaa about something completely different from this achievement, and it helped me get it.

Basically there is a script command to have your ; key mimic the left click of a mouse.. which for me.. helped a ton.

/script SetBinding(";", "CAMERAORSELECTORMOVE")
