Additional Comments
Expander triangle

Handle the scrollbarBeginning message if you want to respond to the use of Shift-click to move the scrollbar thumb directly to the beginning (the top or left) of the scrollbar.

Parameters:

The start is the new position of the scrollbar thumb. This is the same as the scrollbar's startValue property.

Comments:

Dragging the scrollbar thumb to the beginning position, or otherwise moving it to the beginning, does not send a scrollbarBeginning message.

If the scrollbarBeginning message is not handled, a scrollbarDrag message is sent in addition.
