When the user clicks the <xref:System.Windows.Controls.Primitives.Track> of a <xref:System.Windows.Controls.Primitives.ScrollBar>, the <xref:System.Windows.Controls.Primitives.RangeBase.Value> property increases or decreases by the value of <xref:System.Windows.Controls.Primitives.RangeBase.LargeChange*>.

## Remarks
When this property is set to `false` and a mouse click occurs along the <xref:System.Windows.Controls.Slider> away from the <xref:System.Windows.Controls.Primitives.Track.Thumb*>, the <xref:System.Windows.Controls.Primitives.Track.Thumb*> moves in the direction of the mouse click. Instead of moving immediately to the mouse click location, the <xref:System.Windows.Controls.Primitives.Track.Thumb*> moves a distance that is defined by the <xref:System.Windows.Controls.Primitives.RangeBase.SmallChange> property for each mouse click.
When this property is set to `false` and a mouse click occurs along the <xref:System.Windows.Controls.Slider> away from the <xref:System.Windows.Controls.Primitives.Track.Thumb*>, the <xref:System.Windows.Controls.Primitives.Track.Thumb*> moves in the direction of the mouse click. Instead of moving immediately to the mouse click location, the <xref:System.Windows.Controls.Primitives.Track.Thumb*> moves a distance that is defined by the <xref:System.Windows.Controls.Primitives.RangeBase.LargeChange> property for each mouse click.

The effect of multiple mouse clicks can be emulated by pressing and holding the left mouse button until the <xref:System.Windows.Controls.Primitives.Track.Thumb*> is repositioned to the desired location.
