721 ** - \fI switches to italics
722 ** - \fB switches to boldface
723 ** - \fP switches to normal display
724 ** - .dl on a line starts a definition list (name taken taken from HTML).
725 ** - .dt starts a term in a definition list.
726 ** - .dd starts a definition in a definition list.
727 ** - .de on a line finishes a definition list.
728 ** - .ts on a line starts a "tscreen" environment (name taken from SGML).
729 ** - .te on a line finishes this environment.
730 ** - .pp on a line starts a paragraph.
731 ** - \$word will be converted to a reference to word, where appropriate.
732 ** Note that \$$word is possible as well.
733 ** - '. ' in the beginning of a line expands to two space characters.
