인용 :
If you are using a Mac, there are some shortcuts that can get you quickly to some of the panels in the System Preferences. To get to the Sound section in System Preferences, hold down the Alt key and press the button on your keyboard that is used to adjust the sound. The System Preferences will open and you'll be taken directly to the Sound panel. To get to the Display section in System Preferences, hold down the Alt key and press the button on your keyboard used to adjust the screen brightness. The System Preferences will open and you'll be taken directly to the Display panel. To get to the Keyboard & Mouse section in System Preferences, hold down the Alt key and press the button on your keyboard used to adjust the brightness of the keyboard back light (notebooks only). The System Preferences will open and you'll be taken directly to the Keyboard & Mouse panel.
