Webb and Gary,
Thanks for the input on the matter. Yes... it is "over my head" too a tad.

I am thinking it may not be possible.

I am pretty familiar wih many of the hardware controls available.... being a simpit builder. I have a bunch of Goflight units and am planning on a Hagstrom KE72 keyboard encoder and a Phidget 8/8/8 to interface most of the switch inputs in the simpit that aren't already covered by the CH yoke and pedals.
The issue is "accessing" a mouseclick only event without using the screen itself. It seems so close ..... but so far away. "Key -to -Mouse" is almost what I need...... but it requires the panel be displayed on the screen when the key that is linked to the mouse click is pressed.
I need a "Key-To-Mouse" that somehow "remembers" the screen coordinates of where it was on the screen that it is supposed to work on AND accesses that screen as "active" and having Windows focus, even though it isn't.
For the GPWS guage.... I have the written documentation that shows what events trigger the various modes to "go off". That info should allow me to write a custom guage (as a stand alone program) in VB6 that can run on one of the secondary computers in the pit. But that coding will take a LOT of time to write na de-bug. Hoping to avoid that. ;)
Anyway...... thanks again.
best,
..................john
