There's a thread about it on the Amazon Forums
. It looks like the slide show commands work on regular book pages. I haven't tried it yet but others post that it works though the speed of the page turns can't be controlled.
J. True says:
To turn on automatic page turning, press Alt-0. Then press Alt-1 to activate it. Alt-2 stops it.
No, it isn't in the manual.
So far, no one has found a way to regulate the frequency of the page turns.
