A bookmark is a type of link with representative text that makes it easier to navigate documents exported as Adobe PDF. Bookmarks you create in the InDesign document appear in the Bookmarks tab on the left side of the Acrobat or Adobe Reader window. Each bookmark jumps to a page, text, or graphic in your document.
Entries in a generated table of contents are automatically added to the Bookmarks panel. In addition, you can further customize your document with bookmarks to direct a reader’s attention or make navigation even easier. Bookmarks can be nested under other bookmarks.
