Years ago, at Siebel, I would always set up bookmarks and open multiple browser tabs to make the demo flow smoothly. I never wasted time navigating through screens if I could avoid it. I would also change the default font type and size for any demo I gave. This made the text easier to read on a big screen when the viewer was several feet away.
