Hands free I let acrobat turn two pages a second. My computer is too fast for acrobat and I notice if the software isn't up with the keypress it jumps. When I do it on my old computer holding the page down key or space bar works well. I've also set my mouse wheel to advance a page at a turn. Useful on webpages as it frees up my other hand to switch sites.

If you're PhotoReading on the bus set acrobat to turn the pages automatically. Hands free (you'll have to set it up in the preferences) then when you want to PhotoRead a book just Ctrl L and the pages flip for you.
