Hi Everyone, I finally moved from my old PC to a new 27" iMac and love it. However, I ran into an issue when I installed my Microsoft keyboard (Wireless Comfort Desktop 5000). Does anyone know how to switch the "alt" button with the "ctrl" button? I had used "ctrl" for so many functions with my pc (copy/paste, etc) and I just cant get use to hitting the "alt" button for these functions with my thumb now. Is there any resolution to this? Thanks!
