Special Keys

I am using Prograph CPX 1.0.1

   I want an abstract subclass of <<Window>> to handle simple dialogs.
I want the Escape key to do the same thing as clicking the cancel button.
The Special Keys for a window's View don't seem to work, unfortunately.
As far as I can tell all I should do is select "Special Keys" when I have
the window's "View Specification" open, and then navigate the simple
dialogs for associating keys with behaviors. I do this, and I get squat.
Any hints out there?
