Hello! New deepin user here! I have a thinkpad e470 and I got used to using the middle button in the trackpad  and the red ball thingy in the middle of the keyboard to scroll up and down but i cant seem to do this on deepin and i dont know why...

I have searched many linux threads to see if i could find a solution but nothing I tried worked

also i am a very very very new linux user so I have basically no idea how to do anything so if you have any suggestions explain it as if you were explaining it to a child!

thanks for everything!
