The complete code is as follows:
----- 8< ------------------------------begin snip-----------------------
    \def\mystepF% Note that \mystep takes no argument. It just changes
the way 
    % the next item is displayed.
    {% 
      \usecolorset{stwcolors}%             Restore the undimmed colors
valid 
                                % at the beginning of \stepwise.
      \dstep[][\boolean{firstactivation}]% \dstep switches colors. The
                                % optional argument makes it appear only
once.
    }%
    \def\mystepP% Note that \mystep takes no argument. It just changes
the way 
    % the next item is displayed.
    {% 
      \usecolorset{stwcolors}%             Restore the undimmed colors
valid 
                                % at the beginning of \stepwise.
                                % For printing we don't need dimmed
colors
    }%
    \ifhandout%
        \let\mystep=\mystepP
    \else
        \let\mystep=\mystepF
    \fi
    % We define a custom itemize environment which automatically adds
calls to 
    % \mystep:
    \newenvironment{stepitemize}
    {%
      \begin{itemize}
          \let\origitem=\item
                                % Here, the \mystep command is hidden
                                % inside  \item
          \renewcommand{\item}{\mystep\origitem}%
        }
        {%
      \end{itemize}
    }
----- 8< ------------------------------end snip------------------------

\mystepF and \mystepP provide two ways of displaying text: \mystepP for
completely undimmed text, \mystepF for my preferred way of displaying
text in presentations. The flag \ifhandout sets the right way up for the
following environments, here stepitemize.

I hope, this could help you to the further improvement of TeXpower
