On the left thumb cluster I short 2+4 ("
return") and 1+5 ("
command") and get the audible click.
On the right thumb cluster I short 4+7 'I think' ("
ESC" "
1" "
2") and 6+8 ("
forward delete") and get the audible click.
To test, I remapped the 4 locations. The remapping affected the actual "
return" and "
forward delete" keys. The "
ESC-
1-
2" keys were unaffected and the one hidden key was successfully remapped. The "
command" has no key, and and the hidden location was successfully remapped as well. It seems that there are 2 possible hidden keys, one on each thumb cluster. The other location on each thumb cluster appears to be 'connected' to the corresponding key switch locations ("
return" and "
forward delete").
It also seems that even though this is on a 30,xxx PC model (not Mac or Mac switchable, firmware ver. 03/06/99 2.48A) that it does in fact have a "
command" key for Mac use!
This should be done on an Advantage.
P.S.----I don't open my daily driver because I have 4 others that are available or already open
