The command reftex-citation
can also be executed outside a LaTeX
buffer. This can be useful to reference articles in the mail buffer and
other documents. You should not enter reftex-mode
for
this, just execute the command. The list of BibTeX files will in this
case be taken from the variable reftex-default-bibliography
.
Setting the variable reftex-cite-format
to the symbol
locally
does a decent job of putting all relevant information
about a citation directly into the buffer. Here is the lisp code to add
the C-c [ binding to the mail buffer. It also provides a local
binding for reftex-cite-format
.
(add-hook 'mail-setup-hook (lambda () (define-key mail-mode-map "\C-c[" (lambda () (interactive) (let ((reftex-cite-format 'locally)) (reftex-citation))))))
