Despite working on a Mac, I’m using the mouse/trackball less and less. I’ve installed Vimium in my Brave browser; it allows me to follow links by selecting them with easy-to-type letter combinations.
I’ve also programmed my keyboards to send arrow keys when I hold the space bar and press the H, J, K and L keys. That way, I can move the cursor and scroll a page without even leaving the home row with my fingers.
