RefTeX is a specialized package for support of labels, references, citations, and the indices in LaTeX. RefTeX wraps itself round four LaTeX macros: \label, \ref, \cite, and \index. Using these macros usually requires looking up different parts of the document and searching through BibTeX database files. RefTeX automates these time-consuming tasks almost entirely. It also provides functions to display the structure of a document and to move around in this structure quickly.

RefTeX was written by Carsten Dominik and is currently being maintained by the AUCTeX project.
