Programmatically scrollbar scrolling

[fruitbang]

Is there way to scroll legend verticalScrollbar by added buttons? I need to make something like this:

You can set start and end settings of a Slider or a Scrollbar. E.g.:

legend.get("verticalScrollbar").setAll({
  start: 0.5,
  end: 0.5
});

This will position the scrollbar at the middle.
