I mean the normal shift key that you configure on the keyboard tab. For instance, setting J1Up to "move up by 1 in the list", and Shift+J1Up to "move up by a page in the list". Kind of like how the mouse settings allow having the shift button move up/down by a page. I'd like to be able to configure the same approach to page scrolling to my trackball/spinner panel, my mag stik plus panel, and my u360 panel.
