Ultra-thin and completely cable-free, the compact Apple Wireless Keyboard uses Bluetooth technology to connect with your Mac. The Apple Wireless Keyboard has been completely redesigned, inside and out. It features an elegant, ultra-thin anodized aluminum enclosure with low-profile keys that provide crisp, responsive feel. It also has function keys for one-touch access to a variety of Mac features such as screen brightness, volume, eject, play/pause, fast-forward and rewind, Expos, and Dashboard. Its compact design fits on your lap or on even the most crowded desk. And its Bluetooth wireless technology lets you use it just about anywhere within 30 feet of your Mac. The keyboard automatically powers down when youre not using it and turns on instantly as soon as you start typing. This intelligent power management means youll get up to nine months of battery life based on average usage patterns. It also has an on/off switch for when youre away from your computer for a long time.
