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
mode bindings, major mode bindings, and global bindings

- The name of the function that @kbd{C-h f} describes has a default which is
-used if you type @key{RET} leaving the minibuffer empty. The default is
-the function called by the innermost Lisp expression in the buffer around
-point, @emph{provided} that is a valid, defined Lisp function name. For
-example, if point is located following the text @samp{(make-vector (car
-x)}, the innermost list containing point is the one that starts with
-@samp{(make-vector}, so the default is to describe the function
-@code{make-vector}.
