   Then to Enable Trackball Scrolling in Ubuntu 21.10
   Use this simple Command:

   Possibly change the Button Number as of your choice…
   So then to Scroll Up & Down on a Web Page is enough to Press the Button and Roll the Trackball.
   And moreover, as I said on Intro the ‘Page Back’ functionality is preserved on Click and Release.
