That might make sense, yes.  In that case, perhaps we could also add an
option to disable the global keybindings, for advanced users, so that
only the mode specific ones were displayed.

But I would separate this into two changes:
- A "cheatsheet" module
- Support for the cheatsheet module in help-quick-toggle

Because I can then imagine other ways of displaying and using the
cheatsheets (such as the way I proposed).  IOW, I would avoid tightly
coupling the cheatsheet functionality to help-quick-toggle.
