I got a new iMac desktop computer and my hot keys that scale, rotate and move patterns only are not working. Usually if you hit the Tilde symbol with S, R (S~ and R~) and the tilde symbol alone, it scales, rotates and moves the pattern only. Since I've started usuing my new computer the tilde key does not seem to be working to isolate patterns. I have checked and my tilde is working. My space bar is also not working as the quick hand tool.
