I tend to prefer alt-scrollwheel myself. Not sure if that's available in Ubuntu though.
Joycon keys are an interesting idea. I had an idea for a keyboard-mashing library that would map all keys into groups of several directional zones e.g. up down right left, and you could mash generally in the zone of your choice to steer a flight sim or paint or modify paint dynamics. Anyway.
Found myself an old school Kensington trackball. With no scroll wheel. Which is a pain. But I quite like the ball. Shame it's not in the middle of the keyboard.
