Does anyone know a google-able term for split keyboards that have doubled keys down the middle column (B/N, G/H, T/Y, 6/7)?
I see one instance on this page of a keyboard with double "B" key ("Alice layout"), but not the others.
I've been interested in trying a split keyboard, but I like to type those middle keys with either left or right hand depending on the moment, so all the split keyboards I've tried have ended up somewhat annoying, for that reason.
I don't think there is an actual name for that. I actually don't think I have ever seen a keyboard with a layout like the one you describe. I'm not really sure if it was really intentional on the Alice layout. The extra B might just be for extra symmetry between the two halves.
