RefTeX is a specialized package for support of labels, references,
citations, and the index 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.
