If the top popup menu is present, use the Structured Text page type.
For the most part, you can just edit text in the usual way. HTML tags can be mixed in with Structured Text if desired.
Names with internal capitals, [text in brackets], http://URLs , and structured text-style links are made into hyperlinks
Text beginning and ending with *, **, _ or ' is italic, bold, underlined or monospaced respectively
One or more non-blank lines are run together form a paragraph; blank lines separate paragraphs
A one-line "paragraph" followed by a more-indented paragraph makes a heading (use spaces for indenting)
A paragraph beginning with - or * or 0 and a space makes a bullet or numbered list item; list items must all be indented at the same level
A more-indented list item starts a sub-list or makes a preceding paragraph a heading
Highlighted quotes, comments and annotations inserted into a document can begin and end with HTML <blockquote>...</blockquote> tags
If a paragraph ends in '::' and is followed by more indented text, the indented text will be displayed in monospaced font without formatting (as inside HTML <pre> tags) for as long as the indentation continues.
Footnote citations are entered in text as numbers in square brackets '[1]' (no quotes) and the footnote itself is placed on a line that begins '.. [1]' and is followed by the footnote content. Footnotes can be anywhere in the document. Citation numbers and footnotes are bidirectionally linked.
Some or all of the above rules may be escaped, by putting ! at the beginning of a word or a line
