Linux

Very, I only really use my mouse for playing video games at this point. You don't really NEED to use Emacs/Vim/etc, but they do help a lot. Ranger (file manager), cmus (music player), qutebrowser (web browser, full featured unlike Lynx, which I do still like, but I use eww in place of it most of the time), etc, etc. Tons of stuff that can make your setup far, far less mouse dependent. Starting with learning the terminal, then using a twm is how I got to the point where I am now where all non-necessary mouse functions are replaced by keyboard keys. Just note that it did take about ten years to get here, though that wasn't me actively searching for ways to do it, more just naturally making my computer work how I wanted it to without the specific end-goal of zero mouse usage.

Edit: Forgot to include that I did most of this before learning Emacs at all. I've used nano for most of my time on Linux, only switching to Emacs last August. Only thing I didn't have before that was cmus. It also works as an email client, but ehh... I don't feel a strong need to switch away from Thunderbird at this point in time.

As others have suggested, getting more familiar with the terminal and using a tiling window manager will help a lot. And yeah it's a great idea to learn Vim or other advanced terminal editors. I use Helix+Zellij for development, Vim for system configuration, and i3 or Sway for GUI stuff. Also check out w3m for simple web searches.

If you want to get rid of the mouse entirely, you can also try using a programmable keyboard with mouse support. I don't use a physical mouse anymore because I do most things in the terminal, and when I do need a mouse I just use my keyboard to move the cursor. For super mouse-heavy tasks like image editing it's good to keep one around or use a Wacom tablet

One of the early window managers was called Rat poison for this very reason.

As you're doing a bazzite build, it'll come with KDE/GS connect so you can use your phone.

We don't have a window manager in the Ublue space yet other than community images, but fedora atomic offers a sway spin, it won't be bazzite, but it'll run games just as well for the most part.

Step 1: open a terminal emulator of your choice. There's no step 2 because you are already done. All features, 0 dependency on your mouse.

You're welcome :)

To achieve this you will need a tiling window manager like Sway, Hyprland, or i3 and try to use as many CLI-based programs as possible for everything else. For browsers, there are projects like Nyxt (and some others I can't remember) that allow you to use vim or emacs like shortcuts to browse around.

However most GUI apps probably won't support an all-keyboard workflow so you will still need one. Depending on what software you use, however, you could make the vast majority of your regular computing mouse-free

XMonad would make that exceptionally easy. If you want to try it, I’d recommend doing it on NixOS and just forking a working config that uses a tiling window manager. This is a great config that I used as the foundation for my own: https://github.com/gvolpe/nix-config
