I would like to use code folding with Aquamacs but I don't find any reference to do it. I would like to fold the figure and the paragraph. I've already tried all the combination listed here. Can anybody give my a practical example to fold this code? And a \section.

   \caption{A running dog}

I've used C-c,C-o,C-r but it doesn't work....

  • To fold the figure environment use C-C C-o C-e with point inside that environment.

  • @giordano this works, so I can undo this using C-c C-o p. I can fold automatically all the figure? For the section seems I have to do something else...Thanks a lot!

You have to customize TeX-fold-env-spec-list (LaTeX-fold-env-spec-list is more appropriate but the result is just the same if you use only LaTeX and not plain TeX). In your init file add this code

(add-to-list 'TeX-fold-env-spec-list '("[figure]" ("figure")))

Then with C-c C-o C-b (M-xTeX-fold-bufferRET) all figure environments in the current buffer will be folded at once. To fold only figure environments in the current paragraph use C-c C-o C-p (M-xTeX-fold-paragraphRET).

The folding of paragraphs is done using the outline minor mode (see also the Outlining the Document section in AUCTeX manual). You can activate it with M-xoutline-minor-modeRET and then use the Outline menu.

  • Thank a lot, can I do the same with \section and \subsection?
