Maximize

Alternatively referred to as resize or zoom, maximize is an option available for almost any open window in a graphical user interface (GUI) that allows a user to enlarge a window to its maximum size, commonly the full display area of the monitor or screen, or the program window that contains the window being maximized. When a window is maximized you will be unable to move or resize it until it is a window mode. Often you can get into this mode by clicking the same button you used to maximize the window or by double-clicking the title bar.
