(LaTeX2e)
The following methods for font selection may not be used in math mode.
Type styles are specified by three independent components. If a font (the combination of these three components) is chosen which is not available, LaTeX will issue a warning and substitute a similar font.
These may be chosen by either a command so that the choice applies to the text within the command argument, or by a declaration which obeys the usual rules for scope. The two forms are
declaration command \mdseries \textmd Medium Series \bfseries \textbf Boldface Series \rmfamily \textrm Roman Family \sffamily \textsf Sans Serif Family \ttfamily \texttt Typewrite Family \upshape \textup Upright Shape \itshape \textit Italic Shape \slshape \textsl Slanted Shape \scshape \textsc Small Caps Shape \normalfont \textnormal Normal StyleThe
\normalfont
declaration sets series, family, and shape to
the main text font of the document.
When using the Typewriter Family, words will be hyphenated only where
permitted by a \-
command.
