Also, still assuming that the current slide is Intro_bullet_1_1, calling
Results.gotoNextSlide() would have no effect, because Results does not contain the current
slide (that is,
Results.currentSlide is null).

Availability
Flash Player 6 (6.0 79.0).
Edition

Usage
mySlide.gotoPreviousSlide()
Parameters
None.
Returns
A Boolean value, or null. The method returns true if it successfully navigated to the previous
slide; it returns
false if the presentation is at the first slide when the method is invoked (that is,
if
currentSlide.nextSlide is null). The method returns null if invoked on a slide that
doesn’t contain the current slide.
Description
Method; navigates to the previous slide in the slide presentation. As control passes from one slide
to the previous slide, the outgoing slide is hidden and the incoming slide is revealed. If the
outgoing and incoming slides are in different slide subtrees, then all ancestor slides, starting with
the outgoing slide and up to the common ancestor of the incoming and outgoing slides, are
hidden and receive a
hide event. Immediately following, all ancestors slides of the incoming slide,
up to the common ancestor of the outgoing and incoming slide, are made visible and receive a
reveal event.
Typically,
gotoPreviousSlide() is called on the leaf node that represents the current slide. If
called on a nonleaf node,
someNode, then someNode.gotoPreviousSlide() advances to the first
leaf node in the previous slide or “section.”
This method has no effect when invoked on a slide that does not contain the current slide. This
method also has no effect when called from within an
on(hide) or on(reveal) event handler
attached to a slide, if that handler was invoked as a result of slide navigation.
