And there is a comment in `LaTeX-indent-environment-list': Hm, here is a situation that you did not cover. I am not talking about editing an equation, I am taking about filling a badly formatted equation Suppose you have (or have a received) a file of that form \documentclass[a4paper]{article} \begin{document} \begin{equation} a = \left.\int very very long expression in one line\begin{array} a a a \end{equation} \end{document} So the equation is badly indented and consist of very long lines. So I basically want LaTeX-fill-environment to indent the environment correctly, and that thanks to the patch is no better, but I also want long lines to be broken/wrapped So far I have seen that I have to jump the end of long lines, press space and the line is broken/wrapped, but this extra typing is not very comfortable. Did I explain this now better? Regards Uwe
