+
+To put this means of character usage in contact, suppose we want to
+typeset \cs{sqiiint} (``\sqiiint\kern3pt'') from the \textsf{txfonts}
+package.  \textsf{txfonts} is a large package that redefines all text
+and math fonts, which may not be desirable just to typeset a single
+symbol.  The following is how we employ a single \textsf{txfonts}
+symbol without having to load the entire package.
+
+We observe that the symbol in question is character 52 hexadecimal (or
+122 octal) in the \texttt{txexa} table in this document.  The first
+step is to associate \texttt{txexa} with a \TeX\ control sequence;
+here we call it \cs{myfont}:
+
+\vskip 10pt
+\texttt{\string\font\string\myfont=txexa at 10pt}
+\vskip 10pt
+
+(If our document were typeset in a font size other than 10~pt., we
+would specify that size in the above.)  We then define a macro, here
+\cs{mysqiiint}, that sets the font and typesets a single character:
+
+\vskip 10pt
+\texttt{\string\newcommand*%
+\string{\string\mysqiiint\string}\string{%
+\string{\string\myfont\string\char"52\string}\string}}
+\vskip 10pt
+
+The extra pair of curly braces in the above limit the font change to
+the single character we want to typeset.  We can now use
+\cs{mysqiiint} without having to load the \textsf{txfonts} package.
+
+Alas, in this case the symbol winds up being typeset below the
+baseline.  This is an artifact of typesetting a mathematical symbol
+outside of math mode.  The solution is to explicitly raise the symbol
+to the desired height:
+
+\vskip 10pt
+\texttt{\string\newcommand*%
+\string{\string\mysqiiint\string}\string{%
+\string\raisebox\string{10pt\string}%
+\string{\string\myfont\string\char"52\string}\string}}
+\vskip 10pt
+
+Note that the \textsf{amstext} package's \cs{text} command is a useful
+mechanism for typesetting text characters in math mode.

+A simple way to typeset time\index{time signatures} signatures, due to
+\person{Daniel}{Hirst}, is to attach a superscript and a subscript to
+an empty math object.  For example, \verb|${}^3_4$| renders as
+``$\,{}^3_4\,$''.  Because superscripts and subscripts are
+left-justified, some extra padding may need to be added if the beats
+per measure and beat unit contain different numbers of digits.  A
+5\,mu space (``\verb|\;|'') vertically centers the ``8'' relative to
+the ``12'' in \verb|${}^{12}_{\;8}$|~(``${}^{12}_{\;8}$'').  For
+boldface time signatures (e.g.,~``\,\boldmath${}^4_4$\,''), consider
+the boldface-math options presented in \ref{bold-math}.
