A recent addition. Atreus 62.

What is the advantage of key layout like this? Is it faster to type?

This layout is called Colemak-DH, which is a slightly optimized variant of the original Colemak layout.

It was designed to make typing more efficient for your fingers than QWERTY. If you were to analyze the top ten thousand words or so in English, you’d start to notice lots of common bi-grams and tri-grams (two and three letter combinations). Colemak looks to optimize the position of the keys such that these n-grams are typed by “rolling” your fingers from one side of the keyboard to the other. In addition, it places a lot of other common letters in intelligent positions to reduce finger travel. Over longer periods of typing, your total finger travel across the keyboard is greatly reduced in comparison to QWERTY.

In theory, you can type faster on this layout, but in my experience that’s not necessarily true (I type the same speed on Colemak vs QWERTY). But it does feel so fucking good to type on. That alone should be reason enough to consider learning it.
- Hey this is interesting to me! I've only ever known/learned qwerty. How long did it take you to learn a new typing variation? Is it hard not to type the wrong letters when you switch back and forth?
- Does less finger travel make a difference in the long term? For example if you go back to QWERTY do your fingers feels fatigued?
It’s (mostly) Colemak! I use it regularly on my work laptop and when I’m not gaming. It’s so much more comfortable on your fingers since it lets letters roll together and putting the most common letters on the home row. There’s also not as much learning involved because it keeps a lot of they keys on the same hand and keeps a lot of the most common shortcut keys (Q, Z, X, C, V) in the same spot.

It’s so comfortable and much more fluid. If you wish to learn, check out the transitional layouts called Tarmak. They change a few keys at a time to help you learn quickly while not losing that much efficiency.

Colemak keyboard! I love it so much!

What’s the side and front profile like? I’d be concerned about prolonged wrist extension on a hard surface.

I have the keyboardio Atreus. It tooke me about a month to get back up to speed with qwerty. Did you learn colmak before hand or did you learn it on this keyboard?

I also have the Keyboardio Atreus which I love.

I learned Colemak-DH on the side, practicing a little bit every day, until I got to about 40% my QWERTY speed. I had a Ferris Sweep split keyboard that I set up next to my QWERTY keyboard at work, and started using that more regularly. I soon switched to a split Corne full time before getting the Keyboardio Atreus, both of which are configured with the Colemak-DH layout.

This recent 62 key variant of the Atreus is an experiment to see how I feel about having a row of numbers.
- Interesting!
  
  Another row could be useful, but I thought the default layout of the keyboardio Atreus was clever because the second layer put the number keys right under the right hand so it worked like a number pad. Another row for numbers would be useful for gaming though.
I’ve got the same Atreus. When I got it I realized the potential to move the keys around so a quick search led me to minimak. On realizing that just moving 4 or 6 keys could make such a huge difference because of how bad QWERTY really is….

That got me down the rabbit hole of layouts and I too settled on Coleman-DH. I still haven’t gotten entirely back up to speed, and I still make frequent mistakes. It was bad / hard enough that I actually gave up a few weeks ago and switched back to QWERTY; however it was so bad to type that way again that I switched back to Colemak-DH and it has been much easier the 2nd time.
