I use vim a lot but not on the shell
A mistake 3 words earlier?
meta-bbbd (not as elegant, I admit)
delete the whole thing?
ctrl-ak (this is even quicker than vim, especially if capslock is mapped to ctrl)
the control-based emacs movements work system-wide on macos btw. I am using ctrl-p and ctrl-n to go up and down lines, ctrl-a and ctrl-e to go to beginning and end of lines while writing this comment in by browser (which has vimium extension)
Sometimes I wish vim just had full emacs bindings while in insert mode. But I don't like to mess with defaults too much.
I keep thinking I should give vim readline a try though, so maybe today. Thanks for the comment.

With vi (after running "set -o vi"): <esc>kC
(k to move up back one position in history. C to "change" to the end of the line.)
This is equivalent to doing the following with "set -o emacs": <ctrl>pu
Regardless, use what you're comfortable with or can incrementally add to your muscle memory.
