functionKeys

[Richmond]

I have a silly little stack, and the single card contains this script:

on keyDown
   put the keysDown into fld "KEYZ"
end keyDown

and, lo and behold, on tapping a key I get a comma delimited list of the 
keys I am pressing.

BUT, if I am pressing a functionKey it does NOT appear in the list.

Can anybody tell me how to detect if a functionKey is pressed when I 
press another key on my keyboard?

Daft as this may seem, this question is part of a quest to help this 
person:
