I’m sure there’s more logic to it, but there are twelve notes in the chromatic scale, so six rows of four gets you two octaves. Also putting them in rows of four means you get a nice interval (a fifth?) if you go down vertically.
It didn't work for me either, but apparently one of the issues is that it assumes window.speechSynthesis is available which may be disabled via about:config > media.webspeech.synth.enabled.
I'd be fascinated to learn what inspired this absurd keyboard layout!
The fifth is a knight's move away down, or up and to the left. Like other isomorphic layouts, it conceptually tiles infinitely in all directions.
a warning would've been nice about a lack of support? ^^
I'm not the dev, but figured it might help them if they know more details. You on Linux, Win11, Mac, BSD, Mobile?
