bind -p | grep "\C-w":

CTRL+w is a bit more reachable than
Alt+Backspace, so if you prefer to use it for the
backward-kill-word functionality, you can do something like this:
If you want to make the change permanent, add this to your
ZSH doesn't use Readline, but it provides
CTRL+w functionality out of the box, although the provided functionality is closer to
backward-kill-word (Alt+Backspace) in GNU Readline.
