Analysis of information sources in references of the Wikipedia article "Apple keyboards" in English language version.
The Apple Extended Keyboard is designed primarily for users who wish to run operating systems other than the Macintosh system. This keyboard is also useful with applications programs and data communications packages ported from other computers that use function keys.
If your application needs to be able to distinguish the right-hand Option and Control keys from the corresponding keys on the left side of the keyboard, you can cause the keyboard to generate different transition codes for those keys (shown in parentheses in Figure 8-10) by changing the value of the Device Handler ID in Keyboard register 3 from $0002 to $0003.
