  obj = self.bindableObject(type)
  if key.ord < Ncurses::KEY_MAX && !(obj.nil?)
    if key.ord != 0

  elsif [:FSELECT, :ALPHALIST].include?(self.object_type)
    return @entry_field
  else
    return self
  end
end

#checkBind(type, key) ⇒ Object

This checks to see if the binding for the key exists: If it does then it runs the command and returns its value, normally true If it doesn’t it returns a false. This way we can ‘overwrite’ coded bindings.
