Mission Control, formerly Dashboard, Exposé, and Spaces is a feature of the macOS operating system. 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 quickly locate an open window, quickly hide all windows and show the desktop, and to manage windows across multiple monitors or virtual desktops. Dashboard, Exposé, and Spaces were combined together and renamed Mission Control in 2011 with the release of Mac OS X 10.7 Lion.

Mission Control includes 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 key 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 Preferences.

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.)
