A friend said he was watching a presentation where the presenter touched the
mouse, a menu open up and another slide automatically opened up, but it did
not open up as a slide. He asked me how to do this and I automatically said
hyperlinks, but after thinking about it and listening to him explain it
again, that wasn't what he was talking about. I really have no idea what he
was talking about, as I know you can right click on a presentation in slide
show view and get a context menu, but nothing like what he described. I was
wondering if this was something in the new version or if I'm missing
something?

Any ideas?
