Not that I am aware of. However, one thing I learned is that moving to a split keyboard fixes bad typing behavior like tapping T or Y with the wrong hand very quickly.

Such a simple design change but honestly it's a genius move.

I think going custom is your best option. Keyboard enthusiasts often adhere to their "perfect" touch typing methods, and thus there is often no demand for split boards with these duplicate keys, which is a shame.

No feedback about the doubled middle keys, but mouse in the center of your desk? Do you have a third, middle arm? I don't see that being ergonomic at all.

Wait... Left...Right....

...wtf do you use to control your mouse that makes the middle comfortable? lmao

two Eternal Keypads – build one as right, one as left – install VIA firmware and remap

(in between the two halves, people more often choose a trackpad or trackball, usually not enough room for full mouse movement)

EDIT: for split keyboards, you’re basically looking for each half having 7 columns (6 and 5 columns are far more common)

You’ll have to get it custom made. You can learn to do it yourself, design and get it fabricated. Or see if you can pay someone to for it.

I find it funny that most of the responses are variations of you needing to conform to existing designs. We make tools to conform to us, not the other way around.

You can do that on a zsa moondlander and assign those key to be whatever you want.

Edit: except for the B/N. But someone that has bad typing technique and crossover and switching to columnar, my muscle memory only does thaty with T/Y and G/H. Not a problem for the bottom row.

I use a ZSA Moonlander which I programmed to have 2 Ys and 2 Vs so the left and right work like how you're looking for.

It sped up my adoption of using a columnar keyboard. I'm sure some will say I gotta fix my typing, but I definitely have sped up my typing with a split keyboard, even with this quirk.

I've had some fun about thinking how much overlap you need. And while playing with the thought to maximize it, I came to the conclusion that you can just have two keyboards, for each hand one.

I had a similar set of typing habits when I started and found that the bfo9000 suited my needs, may be worth a try for you.

It is ortholinear, rather that the row staggered layout you requested, but does allow the "overreaching" typing style.

Not really something that I'm aware of; you would probably need to build one custom yourself if you wanted that. But I don't think that would be worth the effort. If you get a split keyboard, it's pretty easy to train yourself to use it the "correct" way, hitting T with left and Y with right.

EDIT: Or if you go with a pre-built PCB, you could build a keyboard with a non-standard ortholinear layout like this one, but you'd have to re-learn how to type on that anyway....so just going with a standard split layout is the easiest option.

If you didn't want to make one custom, you could get a programmable keyboard like a ZSA Moonlander and then use a layer to have the three extra keys on the inside be the extra keys you want.

Just buying a split (doesnt even have to be ergo) will fix your problems. I have a charybdis from bastardkb and all my typing flaws were instantly revealed. It honestly took me about a month to get used to it, considering I type on a lot of keyboards and mine is the only split ergo in the office.

As a fellow left-handed split keyboard enthusiast, do what you want. The Ergodash is probably about as close as you're going to get to what you're looking for.

Yeah the Ortho layout is a bit different and you won't get your number overlaps, but it could allow you to do what you are looking for and then change it in the future if you decide you'd rather have other keys there instead of letters.

Also as a person who's job entails typing all damn day, the change in layout has removed a significant amount of hand fatigue I used to get from regular staggered boards.
