For a widget to get key press/release events, the widget first needs to
get the input focus.  You can pass around the input focus by pressing
the tab key.  The Scale widget has the key bindings that you want
already.

If you want to control the Scale widget using arrow keys even when
another widget has the input focus, you have to let the widget to pass
the relevant events to the Scale widget.
