Use the arrow to modify the bounds

[zazasa]

In this example: http://jsfiddle.net/AA6y3/4/ I have a large set of values, but i need to keep the minimum range to 20. So to make it usable im thinking about to use the arrow to modify the bounds instead of scroll the selection, in this way I can have a maximum displayed range, and scroll between the full set of values.

You'll have to do it by yourself, because the slider is not currently capable of doing that.
