Thank you very much for that. 
I have since learned that atspi2 is a multitude of small functions. That file implements some, but not the one I need. 
"atspi2.el is a client library for AT-SPI2 written in Emacs-Lisp. It is meant to write a screen reader, or similar,
in Emacs Lisp.  However, it does not do any toolkit bridge tasks, so
what you are looking for is not implemented/handled in atspi2.el."
So I took that file, and my problem, to the emacs developers list, and there was much enthusiasm for adding the functions that haven't been implemented. 

New problem: What's the best way to learn lisp? Anyone have a favorite book or on-line site?
