I'm a big fan of using the mouse less. When I was having issues, I learned to use the mouse with my left hand. I got used to it enough to be nearly as fast, but I never liked it so it encouraged me to just use keyboard shortcuts.

I thought I invented it, but I've since seen occupational health and safety websites recommend alternating.

Here's a link to an Australian gov PDF: https://www.comcare.gov.au/about/forms-pubs/docs/pubs/safety...

I've seen it in NZ too. I think they suggested swapping the mouse buttons but I prefer to just leave them and do my left clicking with both fingers when using my left hand.
