QUITE!

No, you don't get 2 rawKeyDown events; Livecode can pick up if the 
modifier key is DOWN or UP, when a rawKeyDown (or a rawKeyUp)
signal is passed from one of the other {i.e. non-modifier} keys.

This whole thing is a pox, as I don't have this problem with Windows or 
Linux (because Livecode detects a MOD-keydown as
a rawKeyDown and spits out a Unicode value).

The thing that interests me here is that, in Mac OS 7,8,9, 10.2 there 
was a program called 'Keycaps' which was quite capable of detecting
when a SHIFT key was pressed whether another key was pressed or not. 
This SHOULD mean that somewhere "in the plumbing of Mac OS" some sort of 
rawKey signals are generated.

As Mac OS 10 is a highly modified front-end floating on top of some sort 
of UNIX, and UNIX behaves reasonably similarly to LINUX
I cannot quite see why Livecode is unable to pick up rawKeyDowns for the 
modifier keys.

I cannot recall whether Livecode (aka RunRev) could pick up rawKeyDowns 
in its Mac "Classic" incarnations or not.
