*** PREVIEW OF WEDNESDAY's class - have a happy MLK holiday weekend. ***

  1.  Adding a button, rather adding two buttons, so that
          one button stops an animation and the other button starts
          it up or restarts it.

  2.  Having the animation be stopped, until the user decides to start it.

  3.  Having an animation that has three different layers....

         Actions layer 
              stop();   is the only line in frame one

              goToAndPlay(25);   in is the only line in frame 50

         (We will use the easier to learn ActionScript 2.0, 
          we will NOT use any ActionScript 3.0 until after Spring Break). 

         Buttons layer
              red button has the    on (release) {
                                       stop();
                                    }
                                                ActionScript code.

              green button has the   on (release) {
                                        play();
                                     }
                                                ActionScript code.
         Animation layer
              Frame 1 keyframe
                     Rectangle is off the stage to the left

                     The Rectangle is a Symbol and was converted to
                        a Symbol of type Movie Clip by using either
                        the Modify menu Convert to Symbol command or 
                        else using the F8 function key shortcut.

              Frame 25 keyframe
                     Rectangle is completely on the stage 
                               (It will be at the center of the stage).
                                                  ------
              Frame 50 keyframe
                     Keyframe is identical in every detail to keyframe 25,
                     i.e. the rectangle is in the exact same location.

              Frame 1 to Frame 25 Motion Tween that is either eased in or
                                                    is eased out.

              Frame 25 has a ROTATE either CW or CCW set in its motion
                       tween.    Since Frame 25 is identical to Frame 50,
                       there is no movement except for the rotating like
                       a baton or a propeller.

              Question:  What would happen if you EASED in or EASED out
                         the MOTION TWEEN for Frame 25 ------> Frame 50?

                         Think about it, or better yet, try it.

   F6 is the shortcut to inserting a keyframe (KF).

   F8 is the shortcut for converting the selection to a Symbol.

   Ctrl-Z is the shortcut for Edit menu Undo.  It undoes the last thing
                       you did, then the 2nd to last thing you did, etc.
