I use a similar keyboard layout, it took me a couple of weeks to get back to being able to competently type when I first started using it and now I wouldn't go back. It's not really any different to getting used to the fact that when you hold shift the 1 key inserts and exclamation mark instead, you probably don't consciously hold the shift key and then look around your keyboard trying to work out which key you need to hit.

With keyboards from ZSA[1], you can use their Oryx and Keymapp[2] software to get a live preview of what the keyboard is doing.

That's a throwback! I remember being excited about the Optimus Maximus back around '06! Never heard of any actually making it out into the wild...

The Flux Keyboard should begin shipping this year.

A numpadless atrocity.

you could set up rgb lighting to highlight the sections pretty easily on any decent keyboard I think.

It is out of stock, but even then I would have zero interest in supporting someone (trigger warning) blatantly fascist:

That site is propaganda. Ukrainian forces have fascist battalions (azov), but you probably support them.
