23 ;;; Commentary:
25 ;; RefTeX is a minor mode with distinct support for \ref, \label, \cite,
26 ;; and \index commands in (multi-file) LaTeX documents.
27 ;; - A table of contents provides easy access to any part of a document.
28 ;; - Labels are created semi-automatically.
29 ;; - Definition context of labels is provided when creating a reference.
30 ;; - Citations are simplified with efficient database lookup.
31 ;; - Text phrases can be collected in a file, for later global indexing.
32 ;; - The index preview buffer helps to check and edit index entries.
34 ;; There is an extensive Texinfo document describing RefTeX in detail.
35 ;; One way to view this documentation is `M-x reftex-info RET'.
37 ;; The documentation in various formats is also available at
39 ;; http://www.gnu.org/software/auctex/manual/reftex.index.html
41 ;; RefTeX is bundled with Emacs and available as a plug-in package for
42 ;; XEmacs 21.x. If you need to install it yourself, you can find a
43 ;; distribution at
45 ;; http://www.gnu.org/software/auctex/reftex.html
47 ;; RefTeX was written by Carsten Dominik <dominik@science.uva.nl> with
48 ;; contributions from Stephen Eglen. It is currently maintained by
49 ;; the AUCTeX project.

255 Labels can be created with `\\[reftex-label]' and referenced with `\\[reftex-reference]'.

257 context of the label definition. The selected label is inserted as a
258 \\ref macro.
260 Citations can be made with `\\[reftex-citation]' which will use a regular expression
261 to pull out a *formatted* list of articles from your BibTeX
262 database. The selected citation is inserted as a \\cite macro.
264 Index entries can be made with `\\[reftex-index-selection-or-word]' which indexes the word at point
