RefTeX can display cross-referencing information. This means,
if two document locations are linked, RefTeX can display the
matching location(s) in another window. The
macros are one way of establishing such a link. Also, a
macro is linked to the corresponding
\bibitem macro or a BibTeX
The feature is invoked by pressing C-c &
reftex-view-crossref) while point is on the key argument
of a macro involved in cross-referencing. You can also click with
S-mouse-2 on the macro argument. Here is what will happen for
individual classes of macros:
Display the corresponding label definition. All usual
variants7 of the
\ref macro are active for
cross-reference display. This works also for labels defined in an
external document when the current document refers to them through the
xr interface (see LaTeX xr Package).
Display a document location which references this label. Pressing
C-c & several times moves through the entire document and finds
all locations. Not only the
\label macro but also other macros
with label arguments (as configured with
active for cross-reference display.
Display the corresponding BibTeX database entry or
All usual variants8 of the
\cite macro are active for cross-reference
Display a document location which cites this article. Pressing C-c & several times moves through the entire document and finds all locations.
C-c & is also active in BibTeX buffers. All locations in a document where the database entry at point is cited will be displayed. On first use, RefTeX will prompt for a buffer which belongs to the document you want to search. Subsequent calls will use the same document, until you break this link with a prefix argument to C-c &.
Display other locations in the document which are marked by an index
macro with the same key argument. Along with the standard
\glossary macros, all macros configured in
reftex-index-macros will be recognized.
While the display of cross referencing information for the above
mentioned macros is hard-coded, you can configure additional relations
in the variable
all macros that start with ‘ref’ or end with ‘ref’ or ‘refrange’
all macros that either start or end with ‘cite’
