Close All Desktop Windows

Like any devoted Mac user, by the end of the day, your Desktop is probably scattered with open windows — sometimes a dozen or more. Wouldn't you love to be able to close all those windows at once with a single Close All Windows command? But you don't see such a command in any of the menus, do you?

Well, even though Apple (in its infinite wisdom) has hidden this useful command from mere mortals, you can make it come out and play by doing one of the following:

Hold down the Option key and click any window's red gumdrop Close button.
Hold down the Option key and choose File, Close All. (The Close All command usually reads Close Window, but becomes Close All when you hold down the Option key. Release the Option key and it changes back to Close Window.)
Press Command+Option+W
