\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.
