Use the Wireless Keyboard on your desk, on your lap, or anywhere within 30 feet of your Mac or iPad - all because of its built-in Bluetooth technology. Its compact design takes up 24 percent less space on your desktop than full-size keyboards, so you have extra room to move the keyboard around and mouse comfortably alongside of it. You'll also feel a difference when you type on its low-profile anodized aluminum enclosure with crisp, responsive keys.
Use the function keys for one-touch access to a variety of Mac features such as screen brightness, volume, eject, play/pause, Expose, and Dashboard. The Apple Wireless Keyboard requires just two AA batteries. And its intelligent power management system conserves battery life.
So when you're not using the keyboard, it automatically powers down. The instant you start typing, it turns back on. Use the on/off switch when you're away from your computer for a long time.
