-  Emacs provides extensive help features accessible through a single
-character, @kbd{C-h} (or @key{F1}).  @kbd{C-h} is a prefix key that is
-used for commands that display documentation.  The characters that you
-can type after @kbd{C-h} are called @dfn{help options}.  One help
-option is @kbd{C-h}; that is how you ask for help about using
-@kbd{C-h}.  To cancel, type @kbd{C-g}.  The function key @key{F1} is
-equivalent to @kbd{C-h}.
