Re: Problem exporting code

Hi Thorsten,

Let's assume that you don't use ELPA for installing Org.

When installing a recent Org, either from an archive or from a git
clone, you only need to add the correct load-path, as described in
the manual -- for example:

  (add-to-list 'load-path "~/path/to/orgdir/lisp")

No train will die in your experiments.  :)

But removing Emacs Org is not necessary.

The implication of removing Emacs Org is that some Org functions will
still be autoloaded from Emacs loaddefs.el while the autoloads will
not point to the correct, existing, directory.

No.  You should just install Org as an archive or as a git clone, 
and add the correct load-path.  If you forget to add the load-path,
you will simply be using Org from Emacs, that's all.

I simply use this:

(add-hook 'emacs-lisp-mode-hook 'orgstruct-mode)
(global-set-key (kbd "C-M-]") (lambda () (interactive) (org-cycle t)))
(global-set-key (kbd "M-]") (lambda ()
                              (interactive)
                              (ignore-errors
                                 (end-of-defun)
                                 (beginning-of-defun))
                              (org-cycle)))

C-M-] and M-] fold the whole buffer or the current defun.

Because of the keybindings.

See above.

You're welcome!
