It just occurred to me that Ediff does it in the exact same way as the
Hydra approach.

Initially, it only says "Type ? for help". The "?" key is a toggle, just
like "C-o" is in my previous proposition.  Pressing the actual keys that
are described in the doc popup doesn't close the doc popup, which could
be replicated with `:exit nil'.

And the docstring of Ediff is actually customizable through
e.g. `ediff-long-help-message-word-mode', although it's not
automatically synced with the keymap, like Hydra does it.

I suggest that you look at the Ediff interface if you're not yet
familiar with it. Just don't forget to:

(setq ediff-window-setup-function 'ediff-setup-windows-plain)

or you'll get the horrible multi-frame default setting.
