As mentioned before, primitive font selection commands like
\fontfamily
, \fontseries
, \fontshape
,
\fontsize
, and
\selectfont
are also available to carry out the change.
E.g.,
\fontshape{n}\fontfamily{cmss}\selectfontwill switch to the `cmsansserif' family with `normal' shape.4 This article was set in concrete roman type by simply writing
\fontfamily{ccr}
\selectfont
following the \begin{document}
command.5 Of course, the
\documentstyle
command also specifies a style option (` concrete') which sets up the internal tables for these fonts.
