Well Tim, I suppose the blind do outnumber the handless.
I really feel like this used to be the default. That's how I always did it in macOS going back to the early 2000's.
Only in the last two versions or so did I notice it was no longer the default. I'm glad to see here that I can now re-enable it.
Edit: I see that I do have it enabled. But for some reason there are a lot of programs where it doesn't seem to work anymore, no matter what the settings. Off the top of my head: Half the Adobe programs I use for work.
