  Add a new level (after the last one). The new level has the same
  dimensions as the current level, but contains no objects or strings,
  and the title is set to "New Level".

'^S'
  Save level.

'^T'
  Edit the level title.

'^a' <location>
  Add an object with the current MRU values to that location, if there
  is not already another object of the same class there.

'^c'
  Display the class selection menu.
