\section{Changing Volume}
\begin{table}
\begin{tagmap}{}{}
\config{\%mv[t]} & ``v'' if the volume is being changed\\
\end{tagmap}
\end{table}
The tag produces the letter ``v'' while the volume is being changed and some
amount of time after that, i.e. after the volume button has been released. The
optional parameter \config{t} specifies that amout of time. If it is not
specified, 1 sec is assumed.
The tag can be used as the switch in a conditional tag to display different things
depending on whether the volume is being changed. It can produce neat effects
when used with conditional viewports.
Example: \config{\%?mv2.5{\textless}Volume changing{\textbar}\%pv{\textgreater}}
The example above will display the text ``Volume changing'' if the volume is
being changed and 2.5 secs after the volume button has been released. After
that, it will display the volume value.
