Not that either; rather pre-drawn symbols that could be > moused around, As you intendedly state that you're not searching for a solution in the field of typesetting - where LaTeX comes to mind immediately - I could imagine that you can do it the hard way. First, see the symbols here: http://web.ift.uib.no/Fysisk/Teori/KURS/TeX/symALL.html Split the images into individual ones, and then use a graphics suite, such as Gimp or OpenOffice Draw, to drag them around the screen and combine a formula from them. Surely, you would be massively faster doing it with LaTeX, but there's no mouse involved. :-) Another idea which I haven't tested or confirmed is to use the xfig program. If it contains a library that contains math symbols (that's the part that needs verification), you can import it and then use its symbols to "draw" a forula with them. Again, LaTeX would be the faster solution. :-) Ah, and a final idea, but that doesn't seem to be adopted well: Use MathML and combine it with HTML and CSS. And as you already have guessed: LaTeX is faster. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
