Some applications expect to use keycodes generated
by keys existing on the ITF keyboard. Since the keys
do not exist on the PS/2 keyboard, an accommodation
must be made if the PS/2 keyboard is to be used. In
most cases, it is still possible to use some other key
that is equivalent (generates the same keycode from a
different keycap). To do this, it is necessary to know
which keys are equivalent on the two keyboards.
Table 6 compares the equivalent keys of the ITF and
PS/2 keyboards.
NOTICE: Keyboard keys not mentioned in Table 6 are the
same on both keyboards.
