The report window displays your presentation structure in a text format. The viewer displays each scene in your presentation sequentially. The '[' and ']' symbols represent opening and closing of a section respectively. The first and all encompassing section is 'presentation', inside the presentation are the 'scene' sections, and inside each scene are the 'actor' sections. - Think of the structure just like windows explorer, you have folders within folders and each can contain data. The data in this case are comments and actions - which are listed at the start of each section.

This deconstructed format it is useful for reviewing large complex scenes and finding ways of optimizing your scenes.
