I like the idea. Don't you love those words like "creed" or "scare" that can be typed with one hand!

Foot pedal maybe? Or maybe a dedicated mouse button.

Does your usual computer activity require a lot of mouse work? Ten years ago I went down this path when my coworker caught me adding bindings to my mouse buttons. He sat me down at his machine and showed me vim wasn't just an old fart text editor and that the bindings can be used in other editors.

Ofc if you're not doing text based work this wouldn't apply.

I stopped using a mouse when I moved from desktop to laptop computer because I found the touchpad is so much more convenient for keeping my hand near the keyboard. However, doing this for over 20 years means I'm now very stuck in my habit of needing touchpads with real buttons. All my attempts to get used to the awful buttonless modern touchpads have been an absolute nightmare so far :-(

Doesn't a touch-screen make it easy? When I use my laptop I seldomly use the mouse nowadays. I scroll or tap/move the cursor with my finder on the screen, and I 'fine tune' the location with the arrows.
