the great thing about mac is most of it is based off of a “drag and drop” system. So basicaly if your in doubt as to what to do, try dragging junk around the screen. It will ether do nothing or do something. A good place to actualy go for a vast amount of he common, non-programming, related shortcuts is the mac support fourms. If you want more detailed short cuts google “mac key-board shortcuts” that should bring you to a web site detailing nearly everything you can do in mac. I know it was one of the first five links, two months ago. I’ll look into my bpoatks for the exact link when I get home soonish.
