I agree, I never wanted to get into mechanical keyboards per se — I was always just on the lookout for an ergonomic layout. Mechanical switches are cheaper and cheaper these days, though, and I suspect the premium on high-end keyboards now is more from a combination of the luxury good tax and the lack of economies of scale.

I really wanted to make myself a steno theory for the CharaChorder, but now I don't have time. There's definitely something to be done with keyboards like this and I do reckon you could do better than with the mechanical constraints of the stenotype, but it's not trivial: the extra inputs are hard to make use of if you want to avoid awkward ‘scissoring’ strokes, though there are definitely some comfortable strokes in there to mine.

The physical direction thing is a neat idea but a bit hindered by the fact that the two sides have very different accessibility: typically the inward keypress is much easier than the outward keypress. There might be some pairs that's good for, though, e.g. the backspace/delete pair you mention (if put on the right hand: delete is much less common, in my experience, than backspace).

> So, basically, "grabbing" movements are more natural?

Right, for me at least that seems to be the case. Other Svalboard users seem to pretty unanimously agree that outward movements are worse than inward movements, especially on e.g. the ring finger, but people differ on how the inward/upward/downward movements compare.
