For those looking to replace the mouse at the OS level on macOS (similar vibe), Scoot is pretty good for that... https://github.com/mjrusso/scoot
Is there a Linux version? It looks very handful
It certainly would be but looking at the options tells me that they're hooking into MacOS's widget libs and on Linux there's just so many. What I get by with to go mouseless is Tridactyl for Firefox, warpd for when I need a pointer, and when I absolutely, positively need a mouse, mouse emulation on QMK keyboards never fails me. I only need it these days for dealing with MacOS outside of my Linux VM. I also use keyd in order to remap keyboard shortcuts.

Why in the world are those links side by side?
