This is what I suspected. So I'm thinking I could use ProgLister
created with a plTitleSearch for the active (highlighted) category and
that would give me the list of ProgramInfo matching, and then I can
iterate that list looking for one set to record and use that to set
the value in the theme, once I add that textArea to the specific
window of the theme.

I'm off again tomorrow and hoping to get this working.

Thanks for the input.
