@@ -1473,10 +1473,12 @@ Consider the following list of you encounter problems while working with \verbpd
 	\item The image should have a ``right--handed--coordinate system'': you should be able to take your right hand, point your thumb in direction of the $x$ axis, your first finger in direction of~$y$, and your second finger in direction of the $z$~axis. If that is impossible, once of your axes is reversed and you need to communicate that to \PGFPlots\ explicitly by means of the |x dir=reverse| key (and its variants).
 
 	\item There is a |debug| key to investigate what the algorithm is doing:
-\begin{pgfplotskey}{plot graphics/debug=\marg{true,false} (initially false)}
+\begin{pgfplotskey}{plot graphics/debug=\mchoice{true,false,visual} (initially false)}
 	If you provide |\addplot3 graphics[debug,points={...}]|, \PGFPlots\ will provide debug information onto your terminal and into the logfile. It will also generate extra files containing the determined unit vectors and the linear system used to derive them (one such file for every |\addplot3 graphics| statement, the filename will be the graphics file name and |.dat| appended).
 
 	Without the |debug| key, only the log file will contain brief information what \PGFPlots\ is doing behind the scenes. 
+
+	The choice \declaretext{true} activates log messages. The choice \declaretext{visual} activates log messages \emph{and} places some filled circles at the provided |points|. The choice \declaretext{false} disables all |debug| features.
 \end{pgfplotskey}
