I'd like to modify emacs' behaviour when using reftex, so that after pressing 'C-c [' and choosing a citation format the default regex that comes up is one that will give me the citation I used last (the normal behaviour is to default to the word before the cursor, which is rarely of any use). I often cite the same source many times in a row, particularly when making notes on a single paper, so this would be a nice way to save a few keystrokes, and that's what we're all using emacs for, right :)
I know a little lisp, so I expect I'll end up working out a way to do this myself eventually, but I thought it'd be worth asking around to see if anyone else has done it first, no point re-inventing the wheel. (If you do want this feature, but also don't know how to achieve it, let me know and I'll drop you an email when I've done it.)
Thanks
