Typewriter text in sections with ACM “sig-alternate” document class

Question

I would like to put a \texttt{} block in a section, e.g.

\section{Algorithm \texttt{FSG}}

But the problem of this approach is that the text inside the\texttt{} block does not inherit the size and boldness of the surrounding text, at least with the ACM sig-alternate document class. How could I solve this problem?

Answer 1

Unfortunately the sig-alternate class uses a peculiar¹ way to set the document fonts.

In particular, the \texttt macro selects the font family aett (which belongs to a definitely obsolete package) at size 9pt, independent of context. So you have two problems.

1. Use a boldface version of the Typewriter font.

2. Increase the font size in section titles.

Solution to problem 1

\DeclareRobustCommand{\ttfamily}{\fontencoding{T1}\fontfamily{lmtt}\selectfont}

Solution to problem 2

\DeclareRobustCommand\sectt[1]{{\fontsize{13}{12}\bfseries\ttfamily#1}}

Example document

\documentclass{sig-alternate}

\DeclareRobustCommand{\ttfamily}{\fontfamily{lmtt}\selectfont}
\DeclareRobustCommand\sectt[1]{{\fontsize{13}{12}\bfseries\ttfamily#1}}

\begin{document}

\section{Algorithm \protect\sectt{FSG}}
Algorithm \texttt{FSG}

\end{document}

Newer problems

Due to how the class is written, you won't be able to make a table of contents if a command such as \sectt appears in a section title. But this would happen also with \sqrt and other seemingly innocuous commands

The editors of the conference to which you're submitting the paper may not be happy with these changes.
