Can't scroll using hands - Are there other options? I am physically disabled. Just got a Vizio  tablet this week can do much more than expected using mouth held stylus.

up/down scrolling is a problem. Is there a honeycomb setting or app that will give  me "previous" and "next" buttons or scroll bars?

Other ideas welcome.
Some keyboards like Swiftkey have the option to place arrow keys on the keyboard, which will then allow for scrolling on web pages and such. They also have a free one month trial if you want to try it before you spend money :)
