Slideshow02 Notes, by Ralph Abraham

Scene 1, Root Timeline, Frame 1 (only)

The script (slideshow02.as) goes here.
In addition to slideshow.as, we have
added one function, gotoFunction().

On the stage is (as before) one instance of MC, 
a Movie Clip symbol with a black outline,
and two instances of Button symbols,
backButton and forwardButton.

In addition, the three RadioButton components
have Properties:

Label: Go to 1 (or 2 or 3)
Initial State: False
Group Name: gotoGroup
Data: 1 or 2 or 3
Label Placement: Right
Change Handler: gotoFunction
