I have used the scroll button for controlling lighting with a Graphic Eye system and it works great. Just link all pages to a lighting page (which contains several scenes selections or lighting bitmap buttons to exicute command over the Graphic Eye System) with a push of the schroll button, then use ramp up or ramp down commands to the schroll feature. And on that lighting page link that scroll button back to the previous page. All of my customers love that feature, and I use left and right arrows to scroll favorite pages (besides scrolling pages left to right looks COOL!).

Great feature and good luck!
