You could probably figure out a way to incorporate
a keyboard event into your widget program with
GET_KBRD, but that will, I predict, be one sick
puppy. I wouldn't be surprised if it had the
intuitive usability characteristics of, say,
the table widget. :-)
You would be better off spending the time convincing
your users of the great NEW features of the program.
Or, if you absolutely need the capability, investigating
JD's neat hack for incorporating keyboard events into
widget programs:
