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 one parent, the bookmark under which it is indented. A bookmark is said to be open if its children are visible on screen, and closed if they are not. See section 8.2.2, "Document Outline", in the PDF Reference for more information on bookmarks.
