I'm not sure if we're talking about the same thing. Docstring of `LaTeX-indent-environment-list' says: ,----[ C-h v LaTeX-indent-environment-list RET ] | LaTeX-indent-environment-list is a variable defined in ‘latex.el’. | | Alist of environments with special indentation. | The second element in each entry is the function to calculate the | indentation level in columns. | | Environments present in this list are not filled by filling | functions, see ‘LaTeX-fill-region-as-paragraph’. | | You can customize this variable. | | Value: | (("verbatim" current-indentation) | ("verbatim*" current-indentation) | ("filecontents" current-indentation) | ("filecontents*" current-indentation) | ("tabular" LaTeX-indent-tabular) | ("tabular*" LaTeX-indent-tabular) | ("array" LaTeX-indent-tabular) | ("eqnarray" LaTeX-indent-tabular) | ("eqnarray*" LaTeX-indent-tabular) | ("displaymath") | ("equation") | ("picture") | ("tabbing")) `---- and the one for `LaTeX-fill-region-as-paragraph' says: ,----[ C-h f LaTeX-fill-region-as-paragraph RET ] | LaTeX-fill-region-as-paragraph is an interactive native compiled Lisp | function in ‘latex.el’. | | (LaTeX-fill-region-as-paragraph FROM TO &optional JUSTIFY-FLAG) | | Fill region as one paragraph. | Break lines to fit ‘fill-column’, but leave all lines ending with | \\ (plus its optional argument) alone. Lines with code | comments and lines ending with ‘\par’ are included in filling but | act as boundaries. Prefix arg means justify too. From program, | pass args FROM, TO and JUSTIFY-FLAG. | | You can disable filling inside a specific environment by adding | it to ‘LaTeX-indent-environment-list’, only indentation is | performed in that case. | `---- Now take this small example: \documentclass[a4paper]{article} \begin{document} \begin{equation} a a a a \end{equation} \end{document} %%% Local Variables: %%% mode: latex %%% TeX-master: t %%% End: Put the point inside the equation environment and hit 'M-q', nothing happens. When you type in material, there is a line-wrapping at `fill-column', but that's all. So basically this is what happens with Keita's patch: line-wrapping will happen when you enter math, but hitting 'M-q' later is disabled. Hitting 'TAB' will adjust the indentation of a line, but there is no filling. And there is a comment in `LaTeX-indent-environment-list': ;; The following should have their own, smart indentation function. ;; Some other day. ("displaymath") ("equation") ("picture") ("tabbing")) Best, Arash
