I have one of these: https://artsey.io/ - it has only eight keys, and I love it: https://taoofmac.com/space/blog/2023/08/08/1230

The layout/project is a bit niche, but I can vouch that it works, even if slowly at first (I am mostly right-handed but ordered a left-handed one and it's become quite natural to use, although I will fumble some keys and symbols on occasion).

You can order something like a Keychron keyboard (they have many models that support VIA/QMK and full keyboard remapping) and implement the same layout, or something more "natural" like a mirror layout.
