Keyboard

The Apple USB keyboard has a total of 82 keys, including 12 function keys, a numeric keypad and a set of 4 cursor-control keys. The cursor-control keys are in the inverted-T arrangement.

Keyboard Layout

There are versions of the Apple USB keyboard with different key layouts for three standards used in different parts of the world: ANSI (US and North America), JIS (Japan), and ISO (Europe). Figure 3-2 shows the keyboard layout for the ANSI keyboard. Applications can determine which keyboard is connected by calling the Gestalt Manager and checking for the corresponding value of the gestaltKeyboardType selector:

■gestaltUSBCosmoANSIKbd (value = 198)

■gestaltUSBCosmoJISKbd (value = 200)

■gestaltUSBCosmoISOKbd (value = 199)
