Recognize ALT key Pressed
 

I have a flowchart made up of autoshapes in XL. I have assigned OnAction
events to each shape. The user can progress thru the flowchart by clicking on
the shapes. I only want to allow the user to backup if the ALT key is held
down while clicking on a previously selected shape.

How can I recognize when the ALT key is pressed via code ?

Googling for "windows api keyboard alt key excel", this is the first
result. Looks doable, maybe not easy.
