It would be nice if reftex could use the "file" field of a bibtex item
to open up the actual article. I can imagine two places where one
would want to do this. One is in the *RefTeX Select* buffer that
appears when running 'reftex-citation, where it would be nice if I
could press a key, and the article would open up (preferably using
xdg-open, or whatever AUCTeX defaults to for the given filetype).
Another case is when the point is on some \cite command in a tex file.
It seems like reftex and auctex already has most of the machinery in
place needed to do this, it is mostly a matter of combining them, and
binding the keys?
There is a small snippet on emacswiki/reftex doing something similar,
but there the "file" field is not used, but it all depends on strict
and consistent naming of the pdf's. Beeing able to follow the "file"
field seams cleaner, and sure makes it easier using bibtex/articles
exported by e.g zotero.
