I would prefer a separate post for feature requests. As far as your question, you can try going to Settings->Touch & Pedal Settings->Pedal Actions, tapping the keys field for pedal 1, tap clear, then press the button on the tablet. If it shows up on the dialog as a key, then you can assign actions to that button such as scrolling the page a fixed amount, and you can make that scroll instantaneous to avoid issues with the refresh rate of the screen. If the tablet button does not result in a key press notification, then you won't be able to use it to control anything in MobileSheets. I would instead recommend using a bluetooth pedal to trigger actions.
