Would like to add an up/down button that scrolls up/down when clicked.

Hi

I am pretty new to macros so please forgive me if this is a stupid question. I am creating a datasheet for a conference that will be seen on a touchscreen monitor, and I would like it to be such that someone can walk up to the monitor and scroll up or down easily, so I figured perhaps an up button and a down button would work. Can anyone tell me how to do this? Also is there a was to do this so that the buttons stay on screen while scrolling?

Thanks,
Crash
