Mission Control is a feature of the macOS operating system. Dashboard, Exposé, and Spaces were combined and renamed Mission Control in 2011 with the release of Mac OS X 10.7 Lion. Exposé was first previewed on June 23, 2003, at the Apple Worldwide Developers Conference as a feature of the then forthcoming Mac OS X 10.3 Panther.

Mission Control allows a user to do the following:

Exposé and Mission Control include three separate features for organizing windows and open applications:

In the first two cases, after Mission Control is activated, the user can select any window by clicking on it or selecting it with arrow keys and pressing Enter. Exposé then deactivates, leaving the selected window in the foreground. Using Apple Mighty Mouse, it is possible to select a window using the Scroll Ball, by scrolling in the direction of that window.

The keyboard shortcuts used for activating Exposé can be customized to be any of the function keys, the shift, control, option or command key, the fn key on Mac laptops, or even a mouse button on multiple-button mice (including Apple Mighty Mouse).

Different features of Mission Control can also be activated by moving the mouse to a 'hot corner' of the desktop. This system is off by default; it can be enabled from System Settings.

When Exposé first premiered in 2003, it could be controlled using the F9, F10 and F11 keys.

The Exposé shortcut keys were moved to the F3 key to make room for the "rewind", "play/pause" and "fast forward" keys. On Mac keyboards made after 2004, Exposé can be activated by using the F3 key or in combination with the command key, or on the trackpad of Macbooks supporting multi-touch interface. (However, F9, F10 and F11 can still be used for controlling Exposé with the function modifier key, or by enabling the "Use all F1, F2, etc. keys as standard function keys" setting.)
