These are key codes assigned to specific positions on the main body of the
keyboard.  The letters on the tops of these keys are different for each
country; not all countries use the QWERTY key layout. These keycodes are
best described positionally as shown in Figure 8-10 and Figure 8-11.  The
international keyboards have two more keys that are "cut out" of larger
keys on the USA version.  These are $30, cut out from the the left shift,
and $2B, cut out from the return key.
