However this seems to be impossible to find. I can easily find any combination of any two of these, but not all three. Then if you start about thinking wireless on top - forget about it.
On the other hand every week I see another one of these wildly impractical keyboards that people are making (and in fairness I've also constructed one - although I can't justify actually using it). Just feels bad man.
Depends on what you put under "ergonomic", but you could take a look at the Ultimate Hacking keyboard: https://ultimatehackingkeyboard.com/ (split, ISO layout & mechanical switches, not wireless however).
AFAIK, the only difference (for the UHK keyboard, at least) is that, on the ISO layout, the left-shift key is narrower, in order to make space for an extra key. This is visible for instance if you compare their US (ANSI) and UK (ISO) layout.
I think you’d really like the Dygma Raise. https://dygma.com/
It sounds like what you’ve described.
My daily driver is RGBKB Sol3 and I love it more than a person should love a keyboard. https://www.rgbkb.net/products/sol-3-keyboard-prebuilt
I went deep on keyboards but didn’t go the super minimalist route that I see get posted often. I type at 120wpm+ on QWERTY so “typing faster” was never the issue, just wanted to minimize pain.
It has been few years since I looked at ErgoDox last time there was no support for anything but ANSI layout and I get that most of these are US based creations so naturally US ANSI is the primary layout to support, I just can't justify unlearning my own layout since I have to maintain a fleet of computers and don't want to be reliant on carrying my custom keyboard with me.
- ergonomic split design
- ISO layout
- mechanical switches
