RefTeX is a reference management software package designed for use with Emacs and BibTeX. [1] [2] [3] [4] While it can cooperate effectively with the popular AUCTeX package, it is not strictly necessary to use them together. [3]
RefTeX obviates the need to tediously search through different parts of a LaTeX document and associated BibTeX files when using cross-referencing macros such as \label, \ref, \cite, and \index. It also provides an interface for visualizing and quickly navigating a LaTeX document's structure. [5]
RefTeX is distributed under the GNU General Public License. It was originally written by Carsten Dominik, the author of org-mode and CDLaTeX, with contributions by Stephen Eglen, and is currently maintained by the AUCTeX project. It has been bundled and pre-installed with Emacs since version 20.2. [1]
