The items for which an argument is marked by a # require a number to be typed from the keyboard; it is not echoed and if one feels that a mistake has been made it should be retyped.

Initially only the general table is accessible, and is the only one which is shown. The options t (for totalistic) and m (for semitotalistic) manifest themselves by showing their own specialized little menu. However, to avoid constant switching between menus, the general menu is always updated whenever one of the specialized menus is changed; for the same reason all of the commands for which it makes reasonable sense to do so are repeated in each menu.
