osprette VS trackball

move top pinky key out and down – Azimuth, Balbuzard, Osprette

Osprette (in pink) also seems to be really popular (if you don’t mind the lack of keys)

For an even more configurable mouse, check out the Ploopy mouse and trackballs: https://ploopy.co/

Fully open source, the mouse (that I own) uses QMK for its firmware. Which means I can use key binding layers rather than single buttons. In other words, one button acts like a shift button that modifies the action of the other buttons. So I have easy access to page up/down, mission control (what was exposé in macOS), paste plain (shift+option+cmd+v), etc etc. I don't have anything Emacs specific on the mouse, but my keyboard (Keychron Q10) has several macro keys that I have meta-x and ctrl-g bound to.

If you truly want a mouse built to last, look into a Ploopy (https://ploopy.co/). You can get trackball ones, or a classic style mouse. It's fully open source and uses 3D printed parts, so not only can you easily get it repaired, you can also modify it to your hearts content. Also possible to remap the buttons or even program the microcontroller with custom code to do specific tasks if you wish.

I have no affiliation with https://ploopy.co, but as an enjoyer of their products, I'd urge you to take a look at their mouse & trackball if you want a proper custom mouse/trackball made for keyboard enthusiasts. 10/10 stuff.

Print this to be as loud as possible.

I haven’t gotten around to trying anything from fingerpunch yet (I think their faux fox series is probably their most popular) but I don’t imagine any of their cases meant for trackballs is all that hard to work with (and if you just want a trackball, Ploopy seems to be the go to)
