Ha ha!! Yeah, I'm on a mac. I've been having problems getting it to work. I reset alot of the keys as the commands were interfering with working in maya. Im treading really carefully as there is something happening which randomly shuts down maya when im working. I never have any other applications open either. I'd like to be able to take pictures of the screen tho, I'll try n sort it out.

Thank you

Heres the list of commands for anyone else who hasn't messed up thier keys!!
