This is the official manual for the latest Org-mode release.
You can include literal examples that should not be subjected to markup. Such examples will be typeset in monospace, so this is well suited for source code and similar examples.
#+BEGIN_EXAMPLE Some example from a text file. #+END_EXAMPLE
Note that such blocks may be indented in order to align nicely with indented text and in particular with plain list structure (see Plain lists). For simplicity when using small examples, you can also start the example lines with a colon followed by a space. There may also be additional whitespace before the colon:
Here is an example : Some example from a text file.
If the example is source code from a programming language, or any other text that can be marked up by font-lock in Emacs, you can ask for the example to look like the fontified Emacs buffer1. This is done with the ‘src’ block, where you also need to specify the name of the major mode that should be used to fontify the example2, see Easy templates for shortcuts to easily insert code blocks.

example and in
src snippets, you can add a
switch to the end of the
BEGIN line, to get the lines of the example
numbered. If you use a
+n switch, the numbering from the previous
numbered snippet will be continued in the current one. In literal examples,
Org will interpret strings like ‘(ref:name)’ as labels, and use them as
targets for special hyperlinks like
[[(name)]] (i.e., the reference name
enclosed in single parenthesis). In HTML, hovering the mouse over such a
link will remote-highlight the corresponding code line, which is kind of
You can also add a
-r switch which removes the labels from the
source code3. With the
switch, links to these references will be labeled by the line numbers from
the code listing, otherwise links will use the labels with no parentheses.
Here is an example:
#+BEGIN_SRC emacs-lisp -n -r (save-excursion (ref:sc) (goto-char (point-min))) (ref:jump) #+END_SRC In line [[(sc)]] we remember the current position. [[(jump)][Line (jump)]] jumps to point-min.
Finally, you can use
-i to preserve the indentation of a specific code
block (see Editing source code).
If the syntax for the label format conflicts with the language syntax, use a
-l switch to change the format, for example ‘#+BEGIN_SRC pascal
-n -r -l "((%s))"’. See also the variable
HTML export also allows examples to be published as text areas (see Text areas in HTML export).
#+END_... patterns need to be added

artist-mode5 to allow creating ASCII drawings easily. Using this command in an empty line will create a new fixed-width region.
org-store-linkwhile editing a source code example in a temporary buffer created with C-c ' will prompt for a label. Make sure that it is unique in the current buffer, and insert it with the proper formatting like ‘(ref:label)’ at the end of the current line. Then the label is stored as a link ‘(label)’, for retrieval with C-c C-l.
 This works automatically for
the HTML back-end (it requires version 1.34 of the htmlize.el package,
which is distributed with Org). Fontified code chunks in LaTeX can be
achieved using either the
If you use minted or listing, you must load the packages manually, for
example by adding the desired package to
org-latex-packages-alist. Refer to
-n -r will keep the
labels in the source code while using line numbers for the links, which might
be useful to explain those in an Org mode example code.
 Upon exit, lines starting with ‘*’, ‘,*’, ‘#+’ and ‘,#+’ will get a comma prepended, to keep them from being interpreted by Org as outline nodes or special syntax. These commas will be stripped for editing with C-c ', and also for export.
