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, 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. Exposé was renamed Mission Control in 2011 with the release of OS X Lion. == Usage == Mission Control includes three separate features for organizing windows and open applications: ;All windows : Shows all open and unhidden windows and desktops shrinking their appearance so they all fit on a single screen. On newer Mac keyboards, this is activated from the F3 key, or F9 on older keyboards. On Apple's Magic Mouse or multi-touch trackpads, this can be activated by pulling up on the trackpad with three or four fingers. Mission Control redesigned this feature extensively to show all running desktops. ;Application windows : Also called 'App Exposé'. Shows all open and unhidden windows for the currently active application. During this mode, the user can cycle through windows of different applications by pressing the tab key. This can be activated by pulling down with three or four fingers on a trackpad, the F10 key on older keyboards, by pressing Control + F3 on newer Apple aluminium and Macbook keyboards, or by right-clicking the app's icon on the dock and selecting 'Show all windows'. On OS X 10.6, it could be activated by clicking and holding the application icon in the dock. ;Desktop : Moves all windows off the screen, with just the edges of the windows visible at the side of the screen, giving the user clear access to the desktop and any icons on it. This can be activated by pressing Command F3 on newer Apple aluminum and Macbook keyboards, the F11 key on older keyboards. On a trackpad, it can be selected by placing four fingers on the trackpad and pulling them away from each other. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mission Control (OS X)」の詳細全文を読む スポンサード リンク
