emulate bash key bindings

[Andrey Butirsky <butirsky@xxxxxxxxx>]

Hello,

after 25 years of bash, I'm doing my first steps with Zsh.

I'm trying to reproduce main bash key bindings in Zsh, so I started with:

autoload -U select-word-style
select-word-style bash

But sill, I need to have different word boundaries for some bindings, 
e.g Ctrl+W should kill space-delimeted word.

What is the best way to achieve that? Can I avoid creating custom widgets?

Thanks.
