For example, supposed I'm browsing through my history, and reach this multi-line command I'd typed earlier:
~ >> for f in *; do echo $f done
vim bindings in the ZLE (
bindkey -v), so I can type Esc at this point and use
vim keys to get around, move across lines, etc. I can also do yy to yank the current line. However, there doesn't seem to be an obvious way to copy all these lines.
