Aha, sorry, I completely missed the point of this thread, since I've actually never once used `" in tex...
But actually what I want is in fact the emacs default (nothing to do with euro-quotes; sorry!):
I want the ' and " keys to give opening ` and `` or closing ' and '' when appropriate (emacs does seem to be nearly infallible). this is not quite the same as the current ^`.
And of course the messages are coming so fast and furious that I missed the responses that already do most of what I wanted...
Thanks!
A
