25 | ;; RefTeX is a minor mode with distinct support for \ref, \label, \cite, |
26 | ;; and \index commands in (multi-file) LaTeX documents. | |
f9ad2e24 CD |
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. | |
7c4d13cc | 31 | ;; - Text phrases can be collected in a file, for later global indexing. |
1c25ed90 | 32 | ;; - The index preview buffer helps to check and edit index entries. |
a7ec1775 | 33 | ;; |
4f595e15 | 34 | ;; There is an extensive Texinfo document describing RefTeX in detail. |
f9ad2e24 | 35 | ;; One way to view this documentation is `M-x reftex-info RET'. |
a7ec1775 | 36 | ;; |
a6611c0d | 37 | ;; The documentation in various formats is also available at |

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 | |
