Editing Lightweight markup language (section)

==== Prefixed headings ====
<pre># Level 1 Heading
## Level 2 Heading ##
### Level 3 Heading ###</pre>
The second style is based on repeated markers (e.g. hash <code>#</code>, equals <code>=</code> or asterisk <code>*</code>) at the start of the heading itself, where the number of repetitions indicates the (sometimes inverse) heading level. Most languages also support the reduplication of the markers at the end of the line, but whereas some make them mandatory, others do not even expect their numbers to match.

Org-mode supports indentation as a means of indicating the level.

[[BBCode]] does not support section headings at all.

POD and Textile choose the HTML convention of numbered heading levels instead.

Microsoft Word supports auto-formatting paragraphs as headings if they do not contain more than a handful of words, no period at the end and the user hits the enter key twice. For lower levels, the user may press the tabulator key the according number of times before entering the text, i.e. one through eight tabs for heading levels two through nine.
