whose names contain a match for regular expression @var{regexp}.
Thus, @samp{info fun step} finds all functions whose names
include @code{step}; @samp{info fun ^step} finds those whose names
-start with @code{step}.
+start with @code{step}. If a function name contains characters
+that conflict with the regular expression language (eg.
+@samp{operator*()}), they may be quoted with a backslash.
