You can use the Apple Wireless Keyboard within 30 feet of your Mac or iPad. It has built-in Bluetooth technology. Its compact design takes up 24 percent less space on your desktop than full-size keyboards. Use the function keys for one-touch access to a variety of Mac features such as screen brightness, volume, eject, play/pause, Mission Control, and Launchpad.
The Apple Wireless Keyboard requires two AA batteries. When you’re not using the keyboard, it automatically powers down. The instant you start typing, it turns back on. You can use the on/off switch when you're away from your computer for a long period of time.
