Figure 21-2 Key map of extended keyboard & Numeric keypad
Although most set two make codes are only one-byte wide, there are a handfull of "extended
keys" whose make codes are two or four bytes wide. These make codes can be identified by the fact
that their first byte is E0h. In addition to every key having its own unique make code, they all have
their own unique break code. And certain relationships exist between make codes and break codes.
