In the app contents screen, the Quick Access sidebar provides links to the pages you viewed most recently and to the categories in the app. The sidebar displays on the left in the app contents page.
Use this option when your app contains a lot of pages that would take a long time to search through.
To jump to your most recently-viewed pages:
Select Most recent.
The pages you viewed most recently display.
To jump to a category:
In Categories, select a category.
The category displays with a list of links to the pages it contains.
