Do you actually have to wait for the modal to show up? I was under the impression you could just press ctrl + shift and not wait for the modal and it would still switch layouts, but I could be misremembering.

Regarding muscle memory: That hasn’t been a problem for me as much as some shortcuts just not working.

Some applications seem to insist on controlling these by key codes, but display them as characters mapped to a US ANSI layout, giving me no way to actually configure the one I want for those keys that are physically different between ANSI and ISO.
