#+cindex: minor mode for structure editing
If you like the intuitive way the Org mode structure editing and list
formatting works, you might want to use these commands in other modes
like Text mode or Mail mode as well. The minor mode ~orgstruct-mode~
makes this possible. Toggle the mode with {{{kbd(M-x
orgstruct-mode)}}}, or turn it on by default, for example in Message
mode, with one of:
#+begin_src emacs-lisp
(add-hook 'message-mode-hook 'turn-on-orgstruct)
(add-hook 'message-mode-hook 'turn-on-orgstruct++)
#+end_src
When this mode is active and the cursor is on a line that looks to Org
like a headline or the first line of a list item, most structure
editing commands will work, even if the same keys normally have
different functionality in the major mode you are using. If the
cursor is not in one of those special lines, Orgstruct mode lurks
silently in the shadows.
When you use ~orgstruct++-mode~, Org will also export indentation and
Auto Fill settings into that mode, and detect item context after the
first line of an item.
#+vindex: orgstruct-heading-prefix-regexp
You can also use Org structure editing to fold and unfold headlines in
/any/ file, provided you defined ~orgstruct-heading-prefix-regexp~:
the regular expression must match the local prefix to use before Org's
headlines. For example, if you set this variable to ~";; "~ in Emacs
Lisp files, you will be able to fold and unfold headlines in Emacs
Lisp commented lines. Some commands like ~org-demote~ are disabled
when the prefix is set, but folding/unfolding will work correctly.

for new table formats is in the hands of those who know those formats

For an example of how this strategy works, see Orgstruct mode. In
that mode, Bastien added the ability to use Org's facilities to edit
and re-structure lists. He did this by turning Orgstruct mode on, and
then exporting the list locally to another format, such as HTML, LaTeX
or Texinfo.

;;; The orgstruct minor mode
;; Define a minor mode which can be used in other modes in order to
;; integrate the Org mode structure editing commands.
;; This is really a hack, because the Org mode structure commands use
;; keys which normally belong to the major mode. Here is how it
;; works: The minor mode defines all the keys necessary to operate the
;; structure commands, but wraps the commands into a function which
;; tests if the cursor is currently at a headline or a plain list
;; item. If that is the case, the structure command is used,
;; temporarily setting many Org mode variables like regular
;; expressions for filling etc. However, when any of those keys is
;; used at a different location, function uses `key-binding' to look
;; up if the key has an associated command in another currently active
;; keymap (minor modes, major mode, global), and executes that
;; command. There might be problems if any of the keys is otherwise
;; used as a prefix key.
