To go to a particular subject in the tour, select an item from
the subject menus. The following buttons also allow you to navigate
through the subjects:

   |< PREV  - Go to the PREVIOUS subject.
   [STOP]   - STOP the animation, or quit "AUTO" mode.
   NEXT >|  - Go to the NEXT subject.
   AUTO >>  - Move through the subjects AUTOMATICALLY,
              with timed pauses ("AUTO" mode).

The "AUTO" pause time and the animation speed can be controlled by
selecting "Options" from the "File" menu.

Many sections in the tour provide additional interactive controls
at the bottom of the main window. These controls can be used any
time that they are visible - including when in "AUTO" mode.
