In addition to using text editors like vim or emacs and using a tiling window manager, what other programs do you use to reduce usage of the mouse? I recently discovered warpd which is similar to vimium's hint mode but works globally.
I’ve been using a Tex yoda ii for years and I love it. If you want to avoid leaving “home row” nothing beats a 60% keyboard with a trackpoint! I just bought a Tex Shura but haven’t tried it out yet.
