Each project is made up of one or more pages. A page in AutoPlay is very much like a page in a book. Just like in a book, each page can have different items on it, such as different photographs and text.
An individual project can have up to 250 pages (Standard edition) or 2500 pages (Professional edition).
Note: Pages are the "surfaces" that objects can be placed on.
When you click on the page surface, the page settings are displayed in the properties inspector. Double-clicking on the page surface opens the Properties dialog for the page.
Tip: You can switch between pages by clicking on a page tab at the bottom of the work area, or by double-clicking on a page icon on the page manager.
