Example: "If your screen is cluttered with windows, it may help to minimize the ones you are not currently using."
Minimizing a window temporarily hides it from view without closing it. In Windows, a button for the minimized window is added to the taskbar. In Mac OS X, a small icon for the window is added to the dock. Clicking the window's button or icon will reopen the window. You can then click the maximize button to increase the window's size.
To minimize a window in Windows, click the button with a horizontal line icon in the upper-right corner of a window. In Mac OS X, click the yellow button in the upper-left corner of the window or double-click the title bar.
