What are the expand and collapse buttons?

The green "plus sign" and red "X" buttons next to topics let you expand or collapse all children of that topic. These buttons can be useful when you would like to temporarily hide or expand a portion of your map.

Expand buttons indicate that some topics are currently hidden

When topics have been collapsed, you see the green "plus sign" buttons. You can click any of them to expand the hidden topic(s).

Collapse buttons indicate that topics emanating from that topic can be collapsed

The red "X" collapse buttons don't appear automatically, but if you hover the mouse over a topic that has topics emanating from it, you will see the collapse button. Then you can click it to hide all the direct or indirect "children" of the topic.
