1. Copy the source file \textsf{./HyperTeX/input7.tex} of this DVI file 

\qquad   as a name \textsf{input1.tex}.

\medskip
2. Copy \textsf{myhyper.sty} and \textsf{keyin.sty} in the same directory.

\medskip
3. Rewrite {\sf input1.tex} as you like after the line

\qquad {\color{red}\verb|%%% Rewrite from Here %%%|}

\medskip
4.  For example, the result of the source text
\begin{verbatim}
  \Q{\alpha}
  \E{\yen}
  \keyin{\widehat{}}{$\widehat{x+y}$}
  \keyin{\begin{quote} 0d 0a   0d 0a\end{quote}}{quote}
\end{verbatim}
\quad
in \textsf{input1.tex} is as follows

\medskip
\qquad
\Q{\alpha}
\E{\yen}
\keyin{\widehat{}}{$\widehat{x+y}$}
\keyin{\begin{quote} 0d 0a   0d 0a\end{quote} 0d 0a}{quote}

\medskip
\quad
Here \verb|\keyin{#1}{#2}| means 

\qquad
\verb|#2| is a hot spot

\qquad
\verb|#1| is a string to be copied to clipboard

\qquad\quad
and \textvisiblespace\textsf{0d} means the character with code 
       \textsf{0d} in Hex

\qquad\quad
and {\textvisiblespace\textvisiblespace} is translated into 
\textvisiblespace

\quad
\verb|\E{#1}| means \verb|\keyin{#1}{#1}|.

\qquad
If \verb|#1| contains multiple lines, it should be \verb|\K{#1\K}|

\quad
\verb|\Q{#1}| means \verb|\keyin{#1}{$#1$}|.

\medskip
\quad
See \textsf{./HyperTex/input.tex} for more examples.

\medskip
5.  Make \textsf{input1.dvi} and copy it to \textsf{./HyperTeX/}.

\medskip
6.  Then by clicking \colorbox{green}{\tiny \sf MyHelp} in \textsf{Help TeX}, 
    \textsf{input1.dvi} is shown.

\medskip
\textbf{Remark}.
In the above, \textsf{input1.tex} may be \textsf{input0.tex}$,\ldots,$\textsf{input6.tex}.

If \textsf{foo?.dvi} is indicated by \textsf{Hyper\TeX}, 
then \textsf{?} is replaced by 
\textsf{0,1,$\ldots$,9} and the corresponding DVI files are 
searched in this order. 
Then the DVI file first found is displayed.

\quad
Hence \textsf{input1.dvi} has priority over \textsf{input7.dvi} 
and \textsf{input1.dvi} will not be changed 
even if a new package of \textsf{dviout} is overwritten.
