Latexian's Navigator allows you to see an outline of a LaTeX or BibTeX document and quickly scroll to different sections in the document. The entries update automatically as you make changes to your document. The Navigator can be displayed or hidden using the Show/Hide Navigator command in the "View" menu.
In a LaTeX document, the Navigator includes entries for all part, chapter, section, and paragraph headings (
\part
,
\chapter
,
\section
,
\subsection
,
\subsubsection
,
\paragraph
, and
\subparagraph
). LaTeX
\label
commands are also included in the Navigator. The Navigator also has entries for
\input
and
\include
commands; for these, you can click the

icon to open the document referenced by the command.
For BibTeX documents, the Navigator will include an entry for each bibliographic entry.
You can create a bookmark, comment text that appears in the Navigator, simply by adding a comment to your document that begins with a "!" character, like this:
% !your bookmark text here
