I'm using a Dygma Raise split keyboard with Dvorak as my main layer. The thumb clusters are great for putting difficult to reach keys in more comfortable positions. Second layer has NumPad, Directionals and Functions. Still trying to decide how to make the best use of my other layers.

I use Coleman DH and symbols have never been an issue because I just put them on another layer 😅

I use US layout for programming because it is way better than SR latin. For documents and mails, I use both variants - latin and cyrillic.

I’m having to use US keyboard layout in Oz and not enjoying the half-height Return key very much.

I use Spanish QWERTY layout and it's... weird for coding.

I'm used to it from my whole life so that's what I use but sometimes brackets or special symbols are weird.

I've always wanted to change to use US-International layout. So I can keep ñ and áéíóú, and also have easy access to coding symbols. But I have never got around it.

Anyhow I still think that whoever designed ISO layouts messed up. We should use US international layout. That's my two cents.

I'm using the Czech keyboard, I've put in the time to learn where the various symbols are because I didn't really want to switch constantly between CZ and US like most programmers do. When I write something like těžiště I prefer it not to look like t26i3t2, then delete it, switch keyboards and write it again.

Regarding the various types (like long/short enter, pipe symbol position etc.) I don't have a particular preference, when I switch laptops, I make mistakes for a while, then get used to it

On UK keyboards the £ replaces the $ and $ replaces '

Double quotation marks " are in the same place though so a lot of british programmers don't use single quotation marks because they are hard to press. If your touch typing you have to reach all the way to the bottom right with your right hand little finger and it's just not worth it.

I use the International keyboard because it allows me to type a lot of symbols, but US also serves me fine

Edit: to program, I use the US layout.

I'm using Finnish keyboard layout (same as Swedish basically).

I like how AltGr+7/8/9/0 gives me { [ ] }, it's a very nice grouping. The key next to Z is < > and you get | with AltGr, which is very handy.

Only thing that's mildy annoying from programming viewpoint is that for tilde and backtick, the keys do diacritics - you need to press the diacritic key and space. Backtick is especially fun, because it's shift+acute, space. Meanwhile, the key next to 1 does § ½, which aren't that handy most of the time. I often just stick backtick on that key if I'm particularly assed to customise keyboard keyouts. Similarly, shift+4 is ¤, which is another not a particularly useful character (but I don't mind that, because £ $ € all need to be produced with AltGr, which is at least consistent).

Using the JIS layout. One thing I miss from ANSI is the single and double quotes on my right pinky.(on the same key) Other than that, JIS is a nice layout to do programing with.
