If it says it is RET then setting it sets RET as well.

But I get "C-_ is undefined" so something is different
between us.

A terminal emulator issue, perhaps?

Good idea for a shortcut, I have M-0 run `undo'. Much better

left ring finger straight up to 0, so both minimal or very
close/short movements and equally easy to reset/get back to
asdf/jkl;.
