Well C-h k still works, but that as well only goes so far ...

AFAIR the vim docs break here down as well. The problem is the
composability.

For prefix keys there's the C-h convention to show the bound
keymap. Maybe we could support that as well and show a generated
cheatsheet ({i, a, o, ...} x text objects).

I'm not sure if and how this could work out .. opinions?

Problems:

1. Shadowed keys
   - Rebind them with `evil-define-key' or `evil-declare-key' (or Leo's
     `evil-undefine') or 
   - change initial state to emacs-state (if it's not an editing mode -
     there's a lot of them)

2. Well .. everything that goes above that is not common and may require
   some elisp
   - Feel free to ask here

Well you should change that ;) Really: It takes the possibilities of
Emacs usage to another level.
