'.
(org-reftex-citation)
Use reftex-citation to insert a citation into the buffer.
This looks for a line like
#+BIBLIOGRAPHY: foo plain option:-d
and derives from it that foo.bib is the bibliography file relevant
for this document. It then installs the necessary environment for RefTeX
to work in this buffer and calls `reftex-citation' to insert a citation
into the buffer.
Export of such citations to both LaTeX and HTML is handled by the contributed
package ox-bibtex by Taru Karttunen.
