I had an interesting experience the other day. I have been using split keyboards for years, but only recently began using a Kinesis Advantage 360 Pro as my daily driver for work; I am so use to the layout now, that in instances where I have to use a non-split, or even my older splits, my fingers fail me entirely - like my brain forgot how to type, my thumbs eagerly searching for the thumb cluster that isn’t there.
If you’re needing to physically type on different machines, you could try hasu’s USB2USB device, which is a programmable dongle that sits between the keyboard and computer and applied whatever layout you want.
Piggybacking on this comment, I made one of these, works great but I don’t use it anymore. If anyone wants it feel free to PM me. (I guess we’ll learn how PMs work on Lemmy…)
