Binding to dictionary keys is difficult. You're probably better off
doing that part manually. It is, however, easy enough to bind the
*value* field to a key like:

   controller.theDictionary.userSuppliedKey

And implement something like:

   - (id) userSuppliedKey
   {
       return [keyTextField stringValue];
   }


Hope that helps.
