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
