+It sometimes happens that you want to change the name of a
+variable in a theorem before printing it. This can easily be achieved
+with the help of Isabelle's instantiation attribute \texttt{where}:

+\end{quote}
+To support the ``\_''-notation for irrelevant variables
+the constant \texttt{DUMMY} has been introduced:
+\isa{fst\ {\isacharparenleft}a{\isacharcomma}\ \_{\isacharparenright}\ {\isacharequal}\ a} is produced by
