1. Delete all markers: Mark > Markers > Delete All.
2. Park the cursor in the Timeline EXACTLY where you want the first chapter marker.
3. Make sure to “DE-select ALL” (Shift-Apple-A) so no timeline files are highlighted.

5. Click “Add Chapter Marker”
6. In TOP Box: Type a Chapter Name (and Number (1. 2. 3.) if wanted).
7. Click OK
Move Cursor to where you want the next Chapter to begin and Repeat steps 4 thru 8.
Continue until all Chapters are marked. (Don’t forget to hit “Save”, just in case.)
