\markright
----------
\markright{right head}
The `\markright' command is used in conjunction with the page style
`myheadings' for setting the right heading, leaving the left heading
unchanged. You should note that a "left-hand heading" is generated by
the last `\markboth' command before the end of the page, while a
"right-hand heading" is generated by the first `\markboth' or
`\markright' that comes on the page if there is one, otherwise by the
last one before the page.
