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 \label
and \ref
macros are one way of establishing such a link. Also, a \cite
macro is linked to the corresponding \bibitem
macro or a BibTeX
database entry.
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:
\ref
Display the corresponding label definition. All usual
variants(7) 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 xr (LaTeX package)).
\label
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 reftex-label-alist
) are
active for cross-reference display.
\cite
Display the corresponding BibTeX database entry or \bibitem
.
All usual variants(8) of the \cite
macro are active for cross-reference
display.
\bibitem
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 &.
\index
Display other locations in the document which are marked by an index
macro with the same key argument. Along with the standard \index
and \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 reftex-view-crossref-extra
.
