Add a new command

You can add a new command by adding a key_action. key_action is a Hash and it contains letters and maps to an array containing the description of the key and a Proc object to call. If you do not know what a Proc object is, you can just type code replacing { my_code }.

  @key_actions['e'] = ["description",
                         Proc.new { my_code }]
