Hello, This is my first time posting to this list. First, let me say that LyX has been a great tool for me - I do all my write-ups and homework sets in it now. It certainly makes LaTeX easier and faster to use. So keep up the good work!
That said, I haven't found a way to include most cursive characters in math formulas. There is the \ell, \imath and \jmath, but that's it in terms of lower case cursive. Given that I study physics, characters like the cursive 'r' come up quite a bit. It would be nice if there were a whole cursive alphabet section like one sees for the greek letters. I'm not especially well-versed in LaTeX, so it may be that this falls outside your realm, but if not it would be a much-appreciated feature. Thanks, -Sean
