A family of Microsoft word processing software products for creating web, email, and print documents.
Ctrl+PageDown executes the BrowseNext command. What this does depends on the "browse object" currently selected. When you first start Word, this is set to "Browse by Page," so the command executes Next Page. When you use the Find dialog, then BrowseNext becomes Next Find/Go To. In order to change back to page, click the Select Browse Object button (between the two "browse arrows" at the bottom of the vertical scroll bar) and choose "Browse by Page."
