This text is much better, thanks.  However, it only talks about the
keymaps, whereas the window we pop shows also some key bindings for
each keymap.  The explanatory text should say something about that as
well, I think.  Such an explanation would probably clarify why the
text says "single" in "single key", which currently looks "out of the
blue".
