Outline Fundamentals

Items in the outline are arranged in a hierarchy.  Diamond symbols are used for items that do not have child items.  Triangle symbols are used to indicate items that have children items.  The triangles point to the right when the branch is collapsed.

Many of the commands operate on the current item.  The current item is the item that contains the blinking insertion caret.
