Fulcrum VS miryoku

dude I really think you should consider a sideways-mounted 5-way switch for the thumbs like I did on the fulcrum. I think it would work really well on this form factor

You may be interested by the 40-key version of the Fulcrum

It's tough to use more than 2 or 3 regular thumb keys. Check out the Fulcrum for max ergo thumb functionality

I use 20 keys as my daily driver and it’s been a dream come true. My RSI disappeared and as a bonus I type faster than I did before on regular keyboard.

Fulcrum allows you to use one of the thumb joysticks as a mouse, though i wouldn't recommend it as a full mouse replacement

Although, I guess you could also go with your idea with using one hand for the vowel and one for the consonant and use just two 5way switches. There is actually a DIY keyboard with two 5way switches: https://github.com/dschil138/Fulcrum I think it would work well for kana input.

I think you would really like the fulcrum

I doubt this will be what you are looking for but I did the same thing with the keylogger and had the same realization, which heavily informed my keymap and hardware design on the Fulcrum. Full keymap is at the bottom of the readme page. Also if you go to my profile I have a pinned repo on key press stats that you may find interesting.

Fulcrum would be either your dream keyboard or your nightmare keyboard. Not sure which

I humbly suggest the 40-key version of the Fulcrum, which will give your thumbs a multitude of ergonomic options

I've seen https://github.com/manna-harbour/miryoku but it doesn't appear to be easily modified.

A 75% keyboard still require quite a lot of wrist movement, which is not ideal in your situation. It's better to learn to use layers, you could still have all the function keys and such with a 36 or 34 keys. With with such a small keyboard you don't need to move your wrist while typing. A Corne or even a Ferris Sweep can do the job with a proper keymap, like Miryoku.

If you prefer to have semicolon on Base you'd substitute custom Base, Nav, and Sym layers, swapping semicolon and slash, with https://github.com/manna-harbour/miryoku/discussions/85.

The Miryoku layout [1] has a dedicated number layer which turns the left half into a number pad. Practical (once you get used to it) and portable.

It's understandable if some people would prefer a larger layout. I wouldn't argue people should be using smaller keyboards.

It's "I don't mind moving my hand to hit the key" vs "I don't mind holding down some Fn key to hit the key". (Or with F1-F12 on Macbooks, you need to both hold down a Fn key and move your hand).

For an example of "36 keys ... how", I think the popular miryoku layout is fascinating. https://github.com/manna-harbour/miryoku/tree/master/docs/re... -- Often, mnemonics for particular keys aren't all that complicated.

Except for those who use Miryoku, which is not optimized for software development, probably every single person here will have its own custom keymap.

The keyboard on the other desk is a wireless Corne low profile kit I built up a while back using a couple nice!nano controllers and their low power display too. For general typing I don't have much of a problem going back and forth between the two, but the Corne is only 34 keys and I use a complex layout called Miryoku to get access to most symbols and functions I have by default on my 360.
