There are a lot of touted ergo features: tenting, concave keywell, l/r split, ortho columns, thumb cluster. Of these, the most important IME is the thumb cluster -- giving more work to your thumbs and taking load off your pinkies. This led me to HHKB JP layout for 80/20 ergo benefit without having to carry two unwieldy halves of a keyboard when I want portability. Still use Kinesis Advantage 2 at home, but nothing be…
Same. I’m actually skeptical of some of the claims, particularly in regards to ortholinear/column stagger key arrangements. In particular I feel like this actually makes the layout worse in some situations. For example, consider the `in` bigram in qwerty. It’s one of the most common bigrams in English, and if you switch to most ergo boards, the distance between those keys will _increase_ which will require a bigger s…
In different arrangements of keys, some words will be easier to type than others (and some will be more difficult).
e.g. Comparing Dvorak and qwerty. -- With the example 'in', both of these letters are on home row on Dvorak, whereas both letters require reaching with the fingers on qwerty.
I don't think it's worth putting strong weight on any one example.
I'd point to the distances between (on a typical keyboard); between FT should be the same as JY; and between FB should be the same as JN. -- But on the traditional row stagger, these distances are absurdly different.
I find it hard to believe that the best arrangement of alphabetical keys would be asymmetrical.
