This command displays all entity headings that are currently turned on. It is useful especially after a newpage command. Note that if there are any immediately preceeding or following entity definition commands before or after heading, only one copy of the entity headings is drawn.

Prepending these in front of an entity definition (or later mention) will set the ‘show’ attribute of those entities (there can be a comma separated list) to yes or no, respectively.

Prepending these in front of an entity definition (or later mention) will set the ‘active’ attribute of those entities (there can be a comma separated list) to yes or no, respectively. In addtion, when these commands are used to activate or deactivate certain entities immediately after an arrow, the activation or deactivation will take place at the tip of the arrow and not after it. This is to indicate that the activation or deactivation happened as a result of the arrow. This effect is not applied if an entity is activated or deactivated by setting its active attribute.
