Ctrl-U is bound to "kill" at the terminal level (e.g. stty(1)). It's
more than just a shell feature. You can use it in any setting where
a terminal is in "canonical mode", e.g. "cat" with no arguments reading
from a terminal, or a terminal's login prompt.
I don't know a lot about zsh, but I ran it, typed some letters, and
pressed Ctrl-U, and they were all erased as expected.
One difference that I did notice in zsh is that its handling of Ctrl-U
after a bracketed paste is different from bash's. I used "seq 3 | xclip -i"
to load three harmless lines into the paste selection, and then pasted
it into zsh, and into bash, and pressed Ctrl-U in each of them. In the
zsh case, only the third line was erased, and the first 2 were still
there, and were executed when I pressed Enter. In bash, all 3 lines
were erased, and Enter didn't execute any of them.
Whether that's a bug in zsh, I can't say.
