Mission Control
Mission Control, formerly Exposé is a feature of the OS X operating system. First previewed on June 23, 2003 at the Apple Worldwide Developers Conference as a feature of the then forthcoming Mac OS X v10.3, Exposé allows a user to quickly locate an open window, or to hide all windows and show the desktop without the need to click through many windows to find a specific target. Exposé was replaced in OS X 10.7 by Mission Control.The above text is a snippet from Wikipedia: Mission Control (OS X)
