Keyboard Layout

There are localized versions of the Apple Keyboard for use in different parts of the world. The three standards

used are ANSI (US and North America), JIS (Japan), and ISO (Europe).

Applications can determine which keyboard is connected by calling the Gestalt Manager and checking for the

corresponding value of the gestaltKeyboardType selector.

Figure 3-4 (page 44) shows the keyboard layout for the ANSI keyboard.

MultiMedia Control Keys

The keyboard has six multimedia keys: Volume Up, Volume Down, Mute, Brightness Up (F15), Brightness Down

(F14), and Eject. Theses keys provide direct control of the features on the computer by way of the USB.

Keyboard and USB

The Apple Keyboard is designed to work with the computer by way of the USB ports. The keyboard has a

captive cable with a USB Type A connector. The keyboard is a bus-powered USB hub with two USB Type A

ports.

Warning: A bus-powered hub as defined in the USB specification does not provide enough power to

support a second bus-powered hub. A second bus-powered hub must be connected to a USB port on

the computer or other self-powered hub, not to a port on the keyboard.

Apple provides a HID class driver for the Apple Keyboard, which supports the USB boot protocol. Other keyboards

intended for use on the Macintosh platform must support the HID boot protocol, as defined in the USB Device

Class Definition for Human Interface Devices (HIDs).
