*nods* As long is at can at least handle diagonal arrows, and preferably arrows between not-necessarily adjacent cells. > What LaTeX packages do you use? As you can see from the sample I sent you, for those notes I used xypic. If I were drawing such diagrams now, I'd either use Barr's xydiag, which is a simpler interface layered on xypic, or Paul Taylor's diagram. Both Taylor and Barr are real-life mathematicians writing papers in related areas, so they can be assumed to have a good idea of what diagrams need drawing. Jules
