I want to delete a word by `Ctrl`+`W` in `zsh` like.

```
vim /foo/bar^W
vim /foo/

```

And found a solution for `bash`, but `bind` is not in zsh function.

[Is it possible to configure ctrl-w (delete word)?](https://unix.stackexchange.com/questions/27927/is-it-possible-to-configure-ctrl-w-delete-word)

How can I configure `Ctrl`+`W` as a `delete-word`?
