Check out this video (which I made some time ago), which shows the presentation UI from an application perspective (here a document authoring system) and as a bonus, the application integrates Zmacs (the Emacs of the Lisp Machine)...
Think of the Documentation Examiner a version of Emacs Info. Think of Concordia as a version of an Emacs buffer editing documentation records. The listener a version of the Slime listener. You can also a short glimpse of the graphics editor, IIRC.
