 The datatype\index{*datatype} \isaindexbold{list} introduces two
 constructors \isaindexbold{Nil} and \isaindexbold{Cons}, the
-empty list and the operator that adds an element to the front of a list. For
-example, the term \isa{Cons True (Cons   False Nil)} is a value of type
-\isa{bool~list}, namely the list with the elements \isa{True} and
+empty~list and the operator that adds an element to the front of a list. For
+example, the term \isa{Cons True (Cons False Nil)} is a value of type
+@{typ"bool list"}, namely the list with the elements \isa{True} and
 \isa{False}. Because this notation becomes unwieldy very quickly, the
 datatype declaration is annotated with an alternative syntax: instead of
-\isa{Nil} and \isa{Cons~$x$~$xs$} we can write
+\isa{Nil} and \isa{Cons x xs} we can write
 \isa{[]}\index{$HOL2list@\texttt{[]}|bold} and
-\isa{$x$~\#~$xs$}\index{$HOL2list@\texttt{\#}|bold}. In fact, this
+@{term"x # xs"}\index{$HOL2list@\texttt{\#}|bold}. In fact, this
 alternative syntax is the standard syntax. Thus the list \isa{Cons True
-(Cons False Nil)} becomes \isa{True \# False \# []}. The annotation
+(Cons False Nil)} becomes @{term"True # False # []"}. The annotation
 \isacommand{infixr}\indexbold{*infixr} means that \isa{\#} associates to
-the right, i.e.\ the term \isa{$x$ \# $y$ \# $z$} is read as \isa{$x$
-\# ($y$ \# $z$)} and not as \isa{($x$ \# $y$) \# $z$}.
