I want to add a pointer to the documentation for org-wikinodes.el: http://orgmode.org/worg/org-contrib/org-wikinodes.html Thanks. I've already seen that - I'm not very interesed in camelcase links. However I was planning to look at the implementation to get hints on how to implement good links. I currently (ab)use radio targets, every top level heading is in the format * Page name, which seems to work quite well, but doesnt feel very elegant. My main focus this far has been to get narrowing (I really don't want to risk seeing anything that may distract me) and a back function so that I can go back to previous page. anders ___ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.

[Orgmode] Deriving mode from org-mode
Hi, isn't creating a new major mode derived from org-mode supported? I guess that part of the problem is that org-mode-p doesn't use derived-mode-p. For example: (define-derived-mode org-derived-mode org-mode Org-Derived) and then create a new buffer using org-derived-mode and enter a source block, like this: #+BEGIN_SRC emacs-lisp #+END_SRC and do org-edit-special (C-c ') in that buffer. When finishing editing one gets this message: org-edit-src-exit: This is not a sub-editing buffer, something is wrong anders ___ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
