You probably know that you can choose keyboard shortcuts for Mission Control and Dashboard in the Mission Control pane of System Preferences. But the default shortcuts listed in that preference pane are limited. For Mission Control, for example, you can choose function keys from F1 to F13, but you can’t select, say, F14 or F15; you also have a few other options, such as the right and left Shift and Control keys. You can do the same for Dashboard, though you’re limited to the same range of function keys.
Fortunately, one reader realized that there’s another, more flexible way to assign keyboard shortcuts for these system features: Go to the Keyboard pane in System Preferences and, in the Keyboard Shortcuts tab, select Mission Control or Dashboard and enter whatever keyboard shortcut you want. If the system feature doesn’t already have a shortcut assigned to it, click in the blank area to its right and type your shortcut. If there’s already a shortcut, click on it and replace it with your preferred key combination.
In either case, if you go back to the Mission Control preference pane, you’ll see your new keyboard shortcut there. Note that you can use the same procedure to set keyboard shortcuts for many other system features, such as Launch- pad, the Dock (to hide and display it) and so on.
