If you are a Microsoft Windows user, sometimes you may have multiple applications open and want to get to your Desktop. You can do this by going to each application and clicking the Minimize button. But there is a key on the lower left of your keyboard that has the image of a window on it. This is known as the Windows key or the Command key or the GUI key. Hold it down and press “M”. Presto, all your windows minimize! To get them all back, hold down the Windows key and press Shift and “M” simultaneously.
