Hi guys, I just bought a Macbook today (the one made of aluminum) and I'm having trouble with the Spaces application. The salesperson who assisted me said I can switch between spaces by moving 3 fingers from left --> right on the keypad, but I haven't found that setting. I went to System Prefences-> Expose & Spaces -> Spaces. All it shows is if you want to switch between spaces using ^ Arrow Keys, "\" Arrow Keys, and the Command key. Any help is greatly appreciated!
