### 2.15.8: \markboth

      \markboth{left head}{right head}

The `\markboth` command is used in conjunction with the page style `myheadings` for setting both the left and the right heading. 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.
