Well this has at least confirmed I am not going mad.
I use a wacom tablet a lot on my machine, and occasionally its in front of me when browsing, but i cannot easily scroll up and down pages using it
I was convinced there used to be a way in vivaldi of being able to scroll and pan with the mouse button alone (so an action i could assign to a vivaldi/wacom script so my pen could be used to pan and scroll)
appears while i remember the action, it was way further back in time than vivaldi and was an opera thing 🙂
