Question: Nice mathematical markup ideas?

Hi, I think I will go crazy if I have to type
maple("printf(MathML:-ExportPresentation( ... ))");
one more time. It would be great to have an abbreviate version of this like
or something. Or how about a function available in the question bank editor to translate short LaTeX phrases into mathml? This would solve a huge number of my Maple T.A. issues. Anyway, along these lines, what I'd really like to do right now is ask my students about double integrals and display something like $\int\int_R f(x,y)\ dA$ Any suggestions? Can I use mathml() to display symbols like the integral? Thanks, Marc
