If a document has no outline, but has a table of contents whose
entries are linked, then you can create outlines automatically by
selecting the links and control clicking, or right clicking, the
content view. At the bottom of the contextual menu that pops up is an
option to Create Outline From Selected Links
. PDFClerk Pro will
create an outline item for each link. PDFClerk Pro will attempt to
create a hierarchical outline in as far as the links suggest a
hierarchy, but, if necessary, it is easy to further arrange the
entries into a hierarchy as explained under the heading Editing and
Arranging Outlines below.
