other variables, in case the feature you are looking for is controlled
by an option, not a command. @xref{Apropos}.
-@item C-h i emacs @key{RET} i @var{topic} @key{RET}
+@item C-h i m emacs @key{RET} i @var{topic} @key{RET}
This looks up @var{topic} in the indices of the Emacs on-line manual.
Press @key{,} repetitively until you find what you are looking for.
-@item C-h i emacs @key{RET} s @var{topic} @key{RET}
+@item C-h i m emacs @key{RET} s @var{topic} @key{RET}
This works like the previous command, but it searches for @var{topic}
(which can be a regular expression) in the @emph{text} of the manual
rather than in its indices.
