scrolling down in project 2010

downloaded project 2010. i'm trying to read chapter one. At the bottom of the screen i want to scroll down to see the bottom part of that page, the only thing i can do is going to the next or the previous page. Reducing the font size gives me more text (barely readable) therefore i know there is more text to see.

The question is: How can i move around on a selected page?
