### 14.3 Bib-Cite

Once you have written a document with labels, references and citations, it can be nice to read it like a hypertext document. RefTeX has support for that: `reftex-view-crossref` (bound to `C-c &`), `reftex-mouse-view-crossref` (bound to `S-mouse-2`), and `reftex-search-document`. A somewhat fancier interface with mouse highlighting is provided (among other things) by Peter S. Galbraith’s `bib-cite.el`. There is some overlap in the functionalities of Bib-cite and RefTeX. Bib-cite.el comes bundled with AUCTeX.

Bib-cite version 3.06 and later can be configured so that bib-cite’s mouse functions use RefTeX for displaying references and citations. This can be useful in particular when working with the LaTeX `xr` package or with an explicit `thebibliography` environment (rather than BibTeX). Bib-cite cannot handle those, but RefTeX does. To make use of this feature, try
