+            <description>
+                Built-in pan action is using modifiers from <code>Scene.getInputBindings().getZoomActionModifiers()</code> method.
+		Default value remains <code>MouseEvent.BUTTON2</code>, i.e. mouse wheel, which is compatible with the previous
+                implementation.
