The Table of Contents (TOC) in most projects is organized in chapters with sub-chapters. You can change the structure by moving topics around and by changing their levels. Changing the topic level is referred to as "promoting" or "demoting" a topic – promoting a topic moves it to a higher level in the TOC, demoting it moves it to a lower level.
Topics with sub-topics are automatically displayed as "chapters", shown with a book icon in the TOC.
You can also organize topic files in the Topic Files section in folders and sub-folders, but this is for convenience only. It does not have any effect on the structure of your project.
The topic tools in Project > Manage Topics can be used to move topics up and down in the TOC (Up and Down arrows) and to promote and demote topics (Left and Right arrows). These tools can only be used on single topics.
•The Promote button (left arrow) promotes the current topic to the next level by moving it one step to the left.
•The Demote button (right arrow) demotes the current topic to the next level by moving it one step to the right.
•Just drag the topic to the new position in the TOC. If you drag onto another topic it will become the child of the target topic. If you drag between two topics (position mouse to left of topic icons) it will be inserted between the target topics.
•It is easier to use Cut & Paste to promote and demote topics over large distances in large, complex TOCs.
