I added the existing functions that could be used as values.  Their
descriptions are available by using the hyperlink, so no need to
duplicate that here.  The list is, of course, not exhaustive, as Lisp
programs could define their own functions.

See above: not needed.

Added.

I didn't see any problem here, although I improved the wording to some
extent.

Thanks.
