A Section is a grouping tool to:
enable easy movement of multiple objects
allow objects to be collapsed to get them out of the way
enable nesting of sub-sections (e.g., level 2, 3, 4, etc.).
When you add a New Section, a Section Marker (vertical line) will appear. All Writing Objects added to a section can be collapsed
Tips
Always Add a section before you Add a Heading; they make it much easier to move multiple things around
