I want to use a Bluetooth button to start and stop scrolling. I watched the video and my pop up screen when I get to "Start/Stop Auto-Scroll" is different than the video. My first choice on the screen says FootSwithch(Keyboard)Messages and does not begin with the USB option like in the video. My question is, before I spend money on a Bluetooth button, is this an issue. My thoughts are either it is because I actually do not have a Bluetooth device hooked to the tablet (doubtful) or it is a tablet issue. I am running Android 7.1.1. Additionally, I did not get the two finger tap option for stopping scroll in that popup box either.
