Collapse the top-level topics to show their children and
grandchildren, but completely collapse the final top-level topic.
- '(-1 () : 1 0)

Close the first topic so only the immediate subtopics are shown,
leave the subsequent topics exposed as they are until the second
second to last topic, which is exposed at least one level, and
completely close the last topic.
- '(-2 : -1 *)

Expose children and grandchildren of all topics at current
level except the last two; expose children of the second to
last and completely expose the last one, including its subtopics.
