Hrmm. It works as you want for me, but there may be some other config item I've set. The other alternative is to try: autoload -U select-word-type select-word-type bash which should override C-w to do what you want. I haven't looked at it enough to see if you can get both behaviours simultaneously though (and it requires a fairly recent zsh iirc)
