If you use the code I posted previously, you just have to type C-c [ and
enter a RegExp, for example the name of an author. RefTeX will, then,
parse your bib file and present all hits in a buffer from where you
can choose the correct one(s) by hitting RET (or `m' if you need more
than one citation).
