Hmm, thats exactly what I tried. It's ok when you have 1-20 pages. When I tried this with 500 pages book -- it was a nightmare. It was impossible to scroll needed amount of the pages.
And scroll ball -- only can scroll by one line. It's too long when you need to get 27th page for example.

I need short-keys or onscreen keyboard with next-prev keys.
Is there support site for docs-to-go or I need to contact eDGe support with this problem?
