There used to be a keyboard called Optimizr produced by a company called Matias: https://matias.ca/optimizer/

It hardware-mapped the CapsLock key to be a modifier for a bunch of other things, basically allowing your right hand never to have to move off the home row.

It's been discontinued but I managed to re-do a lot of the functionality in software using (a somewhat older version of) AutoHotkey: https://github.com/jasonincanada/dot-files/blob/master/optim...

There's one there for dvorak too of course
