Why does that matter, for the issue at hand?  This is a kind of rigor
that should have no place in this discussion.  Tassilo is factually
correct: the way he pointed out _is_ the way of asking Emacs about key
sequences that start with a given key.

It does here.

Yes.  So either C-h k or <KEY> C-h will do.
