\begin{Verbatim}[linenos,stepnumber=2,
firstnumber=5,stepnumberfromfirst]
With this key, the first line
and then every line a step
further down is numbered,
thus here 5, 7, 9, ...
\end{Verbatim}
\begin{Verbatim}[linenos,stepnumber=2,
firstnumber=4,stepnumberoffsetvalues]
Without stepnumberoffsetvalues
we would see numbers on lines
4, 6, and 8 and not on 5 and
7 that we get now.
