Method and system for navigating paginated content in page-based  
increments

Abstract

A method and system in a document viewer for scrolling a substantially  
exact increment in a document, such as one page, regardless of whether  
the zoom is such that some, all or one page is currently being viewed.  
In one implementation, pressing a Page Down or Page Up keyboard key/ 
button allows a user to begin at any starting vertical location within  
a page, and navigate to that same location on the next or previous  
page. For example, if a user is viewing a page starting in a viewing  
area from the middle of that page and ending at the bottom, a Page  
Down command will cause the next page to be shown in the viewing area  
starting at the middle of the next page and ending at the bottom of  
the next page. Similar behavior occurs when there is more than one  
column of pages being displayed in a row.
