Is there an inexpensive way (not the Rosco product) to send keyboard commands from the light board or from a 'master' windows PC?  I may have to build the shows just like we did for TOMMY slide projectors so many years ago.

I have absolutely no direct experience, but the many products you'll
get if you Google "VGA Multiplier" (or search directly on Amazon) seem
like they could accomplish that, starting at very low prices.
