I’ve used a US-QWERTY keyboard layout my entire life. I’ve seen other layouts that do things like reduce the size of the enter/backspace keys, move the pipe operator (|) and can’t wrap my head around how I would code on those.
What are your experiences? Are there any layouts that you prefer for coding over US English? Are there any symbols that you have a hard time reaching ( for example)?
I’m not sure how far down the keyboard rabbit hole you are, so I’ll try and assume as little possible.
Generally keyboards like the one pictured are referred to as split keyboards. This one in particular looks like a Corne.
Most vendors sell split keyboards as kits that you’re expected to assemble yourself. This might require soldering and potentially sourcing certain parts (e.g. switches or keycaps) from other vendors. If you aren’t up for that kind of thing and you have the budget for it, some vendors sell pre-built keyboards. Buying a second-hand split keyboard is another alternative.
As for switches, MX and Choc v1 are the most commonly supported switch types. There are dozens of variants of said switch types; the main differences being the force curves and sound profiles.
The particular switches that are available will depend on who you end up buying from. Some keyboards support hotswap sockets, which allow you to quickly swap out different switches of the same type (i.e. MX or Choc). Otherwise you’re stuck soldering your switches onto the board, and if you aren’t satisfied with the switches that are already on the board, you’ll have to desolder them, learn to start liking them or buy a new keyboard. Whichever’s easier.
