I could very well be "M-s". And what you described above is exactly what
`defhydra` does: both bind the functions and wrap helpers around
them. It's like `define-key', but with the automatic doc popup right
after you press the prefix.

Currently, we have "M-s" do a dumb prompt for more keys, with the only
help available on "M-s C-h", which incidentally quits the minibuffer, so
you have to start over. The `defhydra` approach embeds "C-h" right into
"M-s", without quitting the minibuffer, and automatically closes the
hint once an option is chosen.
