A Mojo.Widget.Scroller is available by default in every scene, unless you are manually disabling it. Scroller Widget Page

It is against WebOS UI standards to have an actual scroll bar or buttons.

If you are using fixed positioning for any of your elements, or don't have content that extends past the bottom of the screen, you may not see scrolling action.
