Code review comment for ~sylvain-pineau/checkbox-ng:urwid_manifest

Really like this, I think it is a big improvement over the existing implementation already.

A few of the usability tweaks Maciej mentions could elevate it even further, although I personally think the two radio buttons works in this case. The tweaks I would like are mostly the shortcut related functionality:
 - shortcut keys y/n for selection of bool entries
 - hitting y/n advances the active entry i.e. drops it down a line
 - some kind of surround for the edit widget on natural entries to make them easier to spot
     square brackets could be enough: [ 123 ]
 - hitting return on natural entries advances the active entry

This means that for quick completion of e.g.:
  bool
  bool
  natural
  bool
you could hit:
  y n 123 enter y t
