+\end{itemize}
+
+Try to set the remaining keys from the previous step. The starred
+version defines a new list in case there are still keys that
+cannot be located in the given families. The command below does
+not do anything since the \verb+keyi+ key has already been taken
+from family \verb+famiv+ above.
+\begin{verbatim}
+\setrmkeys*{fami}
+\end{verbatim}
+\setrmkeys*{fami}\par
+
+The normal version will complain (as \verb+\setkeys+) when it
+cannot locate a key which was previously submitted to
+\verb+\setkeys+ and hasn't been set yet by previous commands.
+\textsf{xkeyval} commands can also be used to set \textsf{keyval}
+options as is done to the color of the url created with the
+\textsf{hyperref} package and the scaling of the font used for
+`\textsf{xkeyval}' with the \textsf{helvet} package. (See the
+preamble of the example for the code).
+\begin{verbatim}
+\setrmkeys{famii,famiii}
+\end{verbatim}
+\begin{itemize}
+\item[$\Rightarrow$]
+\setrmkeys{famii,famiii}
+\end{itemize}
+
+Set keys, excluding some keys.
+\begin{verbatim}
+\setkeys{fami,famii,famiii}[keyi,keyiii]{keyi=test 6,keyii=test 7,keyiii=test 8}
+\end{verbatim}
+\begin{itemize}
+\item[$\Rightarrow$]
+\setkeys{fami,famii,famiii}[keyi,keyiii]{keyi=test 6,keyii=test 7,keyiii=test 8}
+\end{itemize}
+
+Test whether a key is defined in a family from the list.
+\begin{verbatim}
+\key@ifundefined{fami,famii}{keyiii}
+{keyiii is not defined in family `fami' or `famii'}
+{keyiii is defined in family `fami' or `famii'}
+\end{verbatim}
+\begin{itemize}
+\item[$\Rightarrow$]
+\key@ifundefined{fami,famii}{keyiii}
+{keyiii is not defined in family `fami' or `famii'}
+{keyiii is defined in family `fami' or `famii'}
+\end{itemize}
+
+Define some keys and macros.
+\begin{verbatim}
+\define@cmdkey[my]{fama}[my@]{keya}[none]{}
+\define@choicekey[my]{fama}{keyb}{a,b,c}[b]{correct input: #1}
+\define@boolkey[my]{famb}{keyc}[true]{}
+\def\testa{\setkeys[my]{fama}}
+\def\testb{\setkeys[my]{famb}}
+\def\testset{\setkeys[my]{fama,famb}}
+\end{verbatim}
+\define@cmdkey[my]{fama}[my@]{keya}[none]{}
+\define@choicekey[my]{fama}{keyb}{a,b,c}[b]{correct input: #1}
+\define@boolkey[my]{famb}{keyc}[true]{}
+\def\testa{\setkeys[my]{fama}}
+\def\testb{\setkeys[my]{famb}}
+\def\testset{\setkeys[my]{fama,famb}}
+Now \verb+\testa+ can only set \verb+keya+, \verb+\testb+ can only
+set \verb+keyb+ and \verb+\testset+ can set both.
+\begin{verbatim}
+\testa{keya}
+  \my@keya\
+\testa{keyb}
+\testb{keyc}
+  \ifmy@famb@keyc true \else false \fi
+\testset{keya=test 11,keyb=c,keyc=false}
+  \my@keya\space
+  \ifmy@famb@keyc true \else false \fi
+\end{verbatim}
+\begin{itemize}
+\item[$\Rightarrow$]
+\testa{keya}
+  \my@keya\
+\testa{keyb}
+\testb{keyc}
+  \ifmy@famb@keyc true \else false \fi
+\testset{keya=test 11,keyb=c,keyc=false}
+  \my@keya\space
+  \ifmy@famb@keyc true \else false \fi
+\end{itemize}
+
+\section{Pointers and values}
+
+First we (re)define some keys.
+\begin{verbatim}
+\define@key{fam}{keyi}{key 1: #1 }
+\define@key{fam}{keyii}{key 2: #1 }
+\define@key{fam}{keyiii}[test 2]{key 3: #1 }
+\end{verbatim}
+\define@key{fam}{keyi}{key 1: #1 }
+\define@key{fam}{keyii}{key 2: #1 }
+\define@key{fam}{keyiii}[test 2]{key 3: #1 }
+
+Pointers can be used to copy the value of other keys in the same
+family. This can be done in two ways. The first example shows `on
+the spot' value saving.
+\begin{verbatim}
+\setkeys{fam}{\savevalue{keyi}=test 12,\savevalue{keyii}=\usevalue{keyi}}
+\setkeys{fam}{keyiii=\usevalue{keyii}}
+\end{verbatim}
+\begin{itemize}
+\item[$\Rightarrow$]
+\setkeys{fam}{\savevalue{keyi}=test 12,\savevalue{keyii}=\usevalue{keyi}}
+\setkeys{fam}{keyiii=\usevalue{keyii}}
+\end{itemize}
+
+However, you can also predefine the keys to be saved for the entire
+document with a single command. Note that we force keys to be saved
+globally. This is necessary here since the commands in the source of
+this document appear in an environment.
+\begin{verbatim}
+\savekeys{fam}{\global{keyi},\global{keyii}}
+\setkeys{fam}{keyi=test 13,keyii=\usevalue{keyi}}
+\setkeys{fam}{keyiii=\usevalue{keyii}}
+\end{verbatim}
+\begin{itemize}
+\item[$\Rightarrow$]
+\savekeys{fam}{\global{keyi},\global{keyii}}
+\setkeys{fam}{keyi=test 13,keyii=\usevalue{keyi}}
+\setkeys{fam}{keyiii=\usevalue{keyii}}
+\end{itemize}
+
+Pointers can be used in default values as well. Remember that the
+previous example used \verb+\savekeys+ for \verb+keyi+ and \verb+keyii+.
+\begin{verbatim}
+\define@key{fam}{keyi}{keyi: #1 }
+\define@key{fam}{keyii}[\usevalue{keyi}]{keyii: #1 }
+\define@key{fam}{keyiii}[\usevalue{keyii}]{keyiii: #1 }
+\setkeys{fam}{keyi=test 14}
+\setkeys{fam}{keyii}
+\setkeys{fam}{keyiii}
+\end{verbatim}
+\begin{itemize}
+\item[$\Rightarrow$]
+\define@key{fam}{keyi}{keyi: #1 }
+\define@key{fam}{keyii}[\usevalue{keyi}]{keyii: #1 }
+\define@key{fam}{keyiii}[\usevalue{keyii}]{keyiii: #1 }
+\setkeys{fam}{keyi=test 14}
+\setkeys{fam}{keyii}
+\setkeys{fam}{keyiii}
+\end{itemize}
+
+\section{Presetting keys}
+
+Simple example of the preset system.
+\begin{verbatim}
+\define@key{fam}{keyi}{keyi: #1 }
+\define@key{fam}{keyii}{keyii: #1 }
+\presetkeys{fam}{keyi=blue}{keyii=\usevalue{keyi}}
+\setkeys{fam}{}\par
+\setkeys{fam}{keyi=red}\par
+\setkeys{fam}{keyii=red}
+\presetkeys{fam}{keyi=red}{}
+\setkeys{fam}{keyii=\usevalue{keyi}}
+\end{verbatim}
+\begin{itemize}
+\item[$\Rightarrow$]
+\define@key{fam}{keyi}{keyi: #1 }
+\define@key{fam}{keyii}{keyii: #1 }
+\presetkeys{fam}{keyi=blue}{keyii=\usevalue{keyi}}
+\setkeys{fam}{}\par
+\setkeys{fam}{keyi=red}\par
+\setkeys{fam}{keyii=red}
+\presetkeys{fam}{keyi=red}{}\par
+\setkeys{fam}{keyii=\usevalue{keyi}}
+\end{itemize}
+
+\section{Application of pointers, values and presets}
+
+\setkeys{Hyp}{urlcolor=black}
+More complicated example of the preset
+system and pointer system. See for more information about this
+example the
+\textsf{xkeyval} article on\par
