Thanks,
I have investigated your suggestion with mixed results. In the Powerpoint setup screen I am able to select items in the text boxes by having the pic send ascii codes for keys 1 through 7 with return. But when in the slideshow mode there is no response. The show is set for manual control - repeating till esc key. I seem to be able to control dialog boxes but not the actual slide selections. Am I not "focused" on the show screen?
