That’s interesting. I was watching someone use one of those ergonomic keyboards the other day and wondering how she could type on it.
I learned touch typing decades ago. I do not think I could type using anything other than the regular keyboard. But I suppose if you learned using the ergonomic keyboard, it’s use would be natural to you.
Your fingers don’t have to be trained differently it’s just placement of hands. I test the ones on display at the big box stores. :) I do love them but for me, very sensitive hearing, HAVE to have quiet keys.
I learned to drive in a '58 Chevy Impala. The cars of that era were heavy, ungainly, and had terrible ergonomics. With each successive car I owned, the ergonomics and maneuverability improved, and everyone adapted.
Adapting to a natural keyboard is much the same. I lay my hands on a regular keyboard today, and wonder how I ever typed on them.
