I'm looking for a keyboard with the following properties:
Something like this, but with angled thumb keys:
Does such a keyboard exist?
Are those thumb keys not angled? Could you describe them, or sketch with Paint, or something? Because those thumb keys look angled.
I don't know of any board that cover 100% of your requirements. I've never looked much into the 34 keys keyboards.
The Piantor is close, but it's wired and 36 keys.
The Totem is 38 keys and adds splay. Might be worth considering though. Here's mine:
But if you meant the thumb keys should angle down, then I think your only option is to design it yourself with the help of one of the online tools for Dactyl type keyboards.
I am not convinced those are a good ergonomic design however. The thumbs are much stronger for a sideways movement. Like playing the bass guitar.
Ergonomic, split and other weird keyboards
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid
