They are not read as keys, but as push buttons...
OPNAPPLE = $C061 ;open apple (command) key data (read)
CLSAPPLE = $C062 ;closed apple (option) key data (read)
These are actually the first two game Pushbutton inputs (PB0
and PB1) which are borrowed by the Open Apple and Closed Apple

corresponding key is pressed.
PB2 = $C063 ;game Pushbutton 2 (read)
This input has an option to be connected to the shift key on
the keyboard. (See info on the 'shift key mod'.)
TAPEIN = $C060 ;bit 7 = data from cassette on Apple II,
or PB3 ;II+, IIe. On IIgs bit 7 reflects the
;status of Game Port Pushbutton 3--
