Bookmarks are a group of links pointing to their destinations – such
as different page views, sections in the current document or to other
documents. Selected word headings or styles can be converted to PDF bookmarks
with a hierarchy of levels you decide, without disturbing the logical
structure of the original Word document.
Bookmarks help readers to browse PDF documents easily, especially when
reading a collection of documents.
Click the 
PDF Links button in the Nuance PDF
toolbar or use the corresponding menu item. This opens the Nuance PDF
Settings for Word dialog box, whose Bookmarks tab offers the following
settings:
Generate Bookmarks, Links, Comments, Tags in resulting
PDF file
Select this checkbox to have changed settings applied to future conversions.
Save Word File Before Conversion, if Possible
Save the Word file before conversion. If it is read-only, this option
is ignored.
Bookmark - Paragraph Style - Level
All the Word headings and styles belonging to the current document are
listed here. Choose the styles to be converted to bookmarks by selecting
checkboxes in the Bookmark column.
Meaning of the checkbox:
Checked (selected): 
Unchecked (de-selected): 
Decide a bookmark level (indent) for each style. Bookmarks are organized
into a navigation tree with different levels – like the heading structure
in Word documents. Select a bookmark, then click on the level number to
modify it. The default is 1.
In the lower selection box, you can specify how to display the target
page view: retain the source page zoom rate, fit page, fit width,
fit height, or fit visible.
