% \title{Making boxed keys to immitate key presses}
% \author{Nick Urbanik}
% \maketitle
% \begin{abstract}
% For laboratory sheets I needed to show to the student when they were to
% press a particular key.  This style provides the |\key| command, which encloses its arguments in a box with rounded corners.

% \section{Producing the documentation}
% Here is a short driver program that can be extracted with the \LaTeX2e
% |docstrip| program.
%    \begin{macrocode}
%<*driver>
\documentclass{article}%
\usepackage{a4,doc}
\EnableCrossrefs   % Make a full index.
\CodelineIndex     % Index by line numbers rather than by page.
\RecordChanges     % Show change history.
\begin{document}
\DocInput{key.dtx}
\PrintIndex
\PrintChanges
\end{document}
%</driver>
%    \end{macrocode}
%    \begin{macrocode}
%<*package>
\ProvidesPackage{key}[\filedate\space\fileversion\space
                     Creates a boxed key image]
%</package>
%    \end{macrocode}
%
% \section{The package that \emph{really} does the work}
% The |fancybox| package does all the work.  This |key| package is
% just using that to do the job here.
%    \begin{macrocode}
%<*package>
\RequirePackage{fancybox}
%</package>
%    \end{macrocode}
%
% \DescribeMacro{key}
% The |key| macro takes one argument.  This argument will be set in a small
% sans serif font with a box that is 0.7em in size, and has rounded corners.
% Really, the work is all done by the |fancybox| package.
%    \begin{macrocode}
%<*package>
\newcommand{\key}[1]{\Ovalbox{\makebox[0.7em]%
                     {{\small\textsf{#1}}\rule[-0.0em]{0pt}{0.7em}}}}
%</package>
%    \end{macrocode}
% This |\endinput| command prevents anything else from being read by
% |docstrip|, such as the character table (what on earth is a character table for?)
%    \begin{macrocode}
\endinput
