Locations - Bookmarks, Table of Contents (Outlines), Annotations Summary
Use this button to open the Locations window, where you can select different
modes - Bookmarks, Outlines, and Annotations Summary list.
There are 2 types of Bookmarks - the ones created by you, and the ones embedded into a PDF file (also known as Table of Contents, Sidebar
Reference or Outlines).
Creating your own bookmark memorizes the current location in an open file. Use the Edit button to delete or rearrange your own bookmarks. Swipe a bookmark to delete it.
Use the blue arrow button to edit the name of a bookmark. To create a new bookmark, either use this Bookmarks window (there's the Add Bookmark button), or tap-and-hold on a PDF page for the annotating menu to come up,
or use the Side Menu.
Embedded bookmarks (Outlines) are structured in a tree hierarchy. To save precious screen space, outlines only for the current level are shown. To see outlines of the next level, press
a blue arrow to the right of the outline of interest.
Select a bookmark or an entry in annotations summary list to instantly go to its location.
