+@code{\\href} provided by the @code{hyperref} package).  While
+the (hyperlinked) text appears like an ordinary @code{\\href} in the compiled
+PDF file, the same text will be hidden when printing the text.  Hiding is
+actually achieved by making the text the same colour as the background, thus
+preserving the layout of the rest of the text.
+
+Further, the commands @code{\\hycon} and @code{\\hycoff} can be used to
+simulate switching option @code{ocgcolorlinks} of the @code{hyperref} package
+on and off.  This package is possibly obsolete.")
