Howdy JOHN,
The code snip at the foot goes a little further and extracts what is between 
the arrow brackets "".   This will let you take mouse action on prompts 
something like:  "Press  to quit" or "et File Name".  If the mouse 
cursor is not inside arrow brackets, clicks are ignored.
You may need to adapt the MseClick and MseGetLoc subs to match the mouse 
routines you are using.  This would normally go inside the loop you use to 
collect the next key from the user.
