The Player toolbar above the Concept pane has two icons to help you navigate to the previous or next   document in the outline. As you use the controls to navigate, the outline expands as necessary to display the next document or documents depending on the document type. You can also navigate documents in the outline by clicking on them.

 

Note about outline bookmarks: When you exit and restart the Player, it can automatically display the last document you were reviewing in the outline. These document bookmarks are saved only if your content provider has published the Player content you are viewing with this bookmarking capability.
