I think it's meant for when you run a command normally, but then realize you should have sudoed (sudid?) it. Though in that situation, I would still be inclined to do "↑ esc a sudo ". It's not a lot more work, but it is a lot less uncertain.

Indeed. I find ctrl-p ctrl-a is faster than going to the cursors.

Whoops, thanks. Should have been ctrl-a, but spelling out muscle memory is, like, hard.

Shoulda sudone it!
