# How to: Specify Whether a Timeline Automatically Reverses
A timeline's <xref:System.Windows.Media.Animation.Timeline.AutoReverse%2A> property determines whether it plays in reverse after it completes a forward iteration. The following example shows several animations with identical duration and target values, but with different <xref:System.Windows.Media.Animation.Timeline.AutoReverse%2A> settings. To demonstrate how the <xref:System.Windows.Media.Animation.Timeline.AutoReverse%2A> property behaves with different <xref:System.Windows.Media.Animation.Timeline.RepeatBehavior%2A> settings, some animations are set to repeat. The last animation shows how the <xref:System.Windows.Media.Animation.Timeline.AutoReverse%2A> property works on nested timelines.
