This is the very thing I’ve been looking for since vimac became proprietary (homerow). I was using Shortcat, which is also a proprietary software and I was having a little bit of concern mainly about security, but this software seems to solve the problem. Thank you for sharing.
Is that really practical? In the video it looks not very useful to me as it does not seem to be very efficient. The mouse is so integrated into MacOS it looks hard to efficiently replace it. Are you or is anyone else actually using this regularly?
Also, I think the other mentioned alternatives look quite similar to that regard.
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.
On linux, you can just install one of the DEs that are keyboard driven. Rat poison is one. I used that with Conkeror (a fully keyboard driven browser with emacs keys) for a long time.
