Select one to examine, and modify, information on that event. The three popup menus in the second line in the darkened area allow you to go to entities, people, and actions that you have defined.
Entities are inanimate objects or places.
People are individuals, groups, and animals that instigate actions. Actions are verbs in descriptions of events. After you have defined an element, you can choose its name in a popup menu in order to visit a screen relating to that element. The names are listed in alphabetic order. Clicking on a radio button at the right of the screen, then choosing an element from a popup menu, adds the element to one of the lists at the right, as described below in the section on Event Frame Coding .
