Par2: Trapping ESC key on a window
1999-03-22 -- Tony York
 
Here is what you do

1. In the window editor, right mouse button on the window object and select Alerts.

2. Add an alert of EscKey. You will have to write it, as pressing the keys will not 
generate the code for you.

3. In the Window event handling - PreAlert place the command cycle.

4. In the Window event handling - AlertKey place a command like
CancelPressed = True or what ever code you wish. However if you use a form and 
want to wait until the very end to see what response the user might make to a request 
to save the data, then just the CancelPressed = True is best (declare as a byte in the 
data section) and place your other code in the after closing window embed using if 
statements like 

if CancelPressed then
if OriginalRequest = InsertRecord then
   if LocalResponse = RequestCancelled
!code
   end
end
end
