In a previous example, “Paging through an FxHScrollBar in Flex Gumbo”, we saw how you could change the horizontal scroll position a single page up or page down in a Flex Gumbo FxHScrollBar component by using the page() method.

The following example shows how you can change the horizontal scroll position a single line up or line down in a Flex Gumbo FxHScrollBar component by using the step() method.
