You can use HTML tags, too.
Some useful ways to use HTML:

Put text in a <tt>typewriter font</tt>. The same font is generally used for <code>computer code</code>.

<strike>Strike out</strike> or
underline text, or write it

in small caps.

Superscripts and subscripts:
x2, x2

Invisible comments that only appear while editing the page.

Comments should usually go on the talk page, though.

HTML markup should be used sparingly,
and only if it is difficult or impossible to
achieve the desired result otherwise.
