Let's say you have multiple applications open at the same time (internet browser, iTunes, Mac App Store, mail program, Microsoft Office,etc. etc.). And all of these windows are stacked one on top of the other…thus a lot of windows to close, minimize, or move around to get to the desktop. The fastest way I get to the desktop is using the F11 key.
Because the F11 key has functions usually shared with it (such as "volume down")…to get the F11 key…you have to press the "fn" key first. So give it a try…and see if you like it. Have a bunch of windows open…then press "fn" and the F11 key…and see what happens.
Then do the same thing to put all the windows back where they were.
