Handle to a PDF bookmark object, which allows the user to navigate interactively from one part of the document to another. It consists of a tree-structured hierarchy of bookmarks. Each bookmark has:

• A title that appears on screen
• An action that specifies what happens when the user clicks on the bookmark

The typical action for a user-created bookmark is to move to another location in the current document or outside of it. Each bookmark in the bookmark tree structure has zero or more children that appear indented on screen, and zero or more siblings that appear at the same indentation level. All bookmarks except the bookmark at the top level of the hierarchy have an one parent, i.e., the bookmark under which it is indented. A bookmark is said to be open if its children are visible on the screen, and closed if they are not.

See the section 8.2.2, "Document Outline," in the PDF Reference for more information on bookmarks.
