auctex: Outline

 
 3.3 Outlining the Document
 ==========================
 
 AUCTeX supports the standard outline minor mode using LaTeX/ConTeXt
 sectioning commands as header lines.  SeeOutline Mode (emacs)Outline
 Mode.
 
    You can add your own headings by setting the variable
 'TeX-outline-extra'.
 
  -- Variable: TeX-outline-extra
      List of extra TeX outline levels.
 
      Each element is a list with two entries.  The first entry is the
      regular expression matching a header, and the second is the level
      of the header.  A '^' is automatically prepended to the regular
      expressions in the list, so they must match text at the beginning
      of the line.
 
      See 'LaTeX-section-list' or 'ConTeXt-INTERFACE-section-list' for
      existing header levels.
 
    The following example add '\item' and '\bibliography' headers, with
 '\bibliography' at the same outline level as '\section', and '\item'
 being below '\subparagraph'.
 
      (setq TeX-outline-extra
            '(("[ \t]*\\\\\\(bib\\)?item\\b" 7)
      	("\\\\bibliography\\b" 2)))
 
    You may want to check out the unbundled 'out-xtra' package for even
 better outline support.  It is available from your favorite emacs lisp
 archive.
