This event will never occur if the content within the scroll pane is shorter than the available visible area because then the content cannot be scrolled.
+			This event provides the :Percent attribute, a number from 0 to 100 (the same as the ScrollTo action above) representing the percentage that the user has now scrolled down the page as of the event occuring.  This event also provides :Change, representing how much the user's scroll location has changed in the same unit as above (although this value will be negative if the user scrolled up).</event>

+
 			<event name="MouseDown">This event occurs when the user presses the mouse button on the widget.  This differs from the 'Click' event in that the user must actually press and release the mouse button on the widget for a Click event to fire, whereas simply pressing the mouse button down will cause the MouseDown event to fire.</event>

+			Note: The Click, Wheel, MouseDown, and MouseUp events provide several pieces of useful information, including :shiftKey, :ctrlKey, :altKey, and :metaKey, which are 1 if the respective key is held down and 0 otherwise. These events also provide :button, a number representing the button number that the user used to execute the event (which appears to always be 0 for wheel).
