Hi there. I'm a relative newbie on my way to creating my first config. I'm struggling to figure out how some devices seem to automatically create the bottem far left and far right hard buttons as up and down. This scrolls up or down to the next page of that devices.

While other devices seemingly setup the same way. These up and down buttons don't appear. I'm stumped as I would like to be able to use this in part of my config.

Thanks in advance!
Michael
