Sorry, hit return at the wrong moment.
Add trigger buttons to presenter console, at the simplest level to fire off an external script. Why?. To do things like dim house-lights, switch projector channels, and trigger video tape players.
Thanks for new idea
IMHO button "Exit fullscreen mode" in console will also help in this situation. We can easily switch to another program and do what we needed.
PS: we can try Alt-Tab, but on Windows 7 it results in problem, slide from target screen disappears.
Sounds like a neat idea. Moving to NEW.
