reftex-view-crossref

reftex-view-crossref is an interactive autoloaded Lisp function in `reftex-dcr.el'.


(reftex-view-crossref &optional ARG AUTO-HOW FAIL-QUIETLY)

View cross reference of macro at point. Point must be on the KEY
argument. When at a `\ref' macro, show corresponding `\label'
definition, also in external documents (`xr'). When on a label, show
a locations where KEY is referenced. Subsequent calls find additional
locations. When on a `\cite', show the associated `\bibitem' macro or
the BibTeX database entry. When on a `\bibitem', show a `\cite' macro
which uses this KEY. When on an `\index', show other locations marked
by the same index entry.
To define additional cross referencing items, use the option
`reftex-view-crossref-extra'. See also `reftex-view-crossref-from-bibtex'.
With one or two C-u prefixes, enforce rescanning of the document.
With argument 2, select the window showing the cross reference.
AUTO-HOW is only for the automatic crossref display and is handed through
to the functions `reftex-view-cr-cite' and `reftex-view-cr-ref'.
