On MacOS I've been using homerow.app which does the same thing as Scoot but looks a bit more polished.

I like Shortcat

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 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?

There's Vimium Everywhere, a very recent tool for Linux of mine. I don't know of any other. https://github.com/phil294/vimium-everywhere

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.

There's also good old i3, which has vim-inspired key maps by default iirc

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.

Anything like this for Windows?
