How to make zsh forward-word behaviour same as in bash/emacs

I have this in my .zshrc for exactly that purpose:

# Bash-like navigation
autoload -U select-word-style
select-word-style bash

Edit: Ah, I remember what was missing in order to get everything working as I wanted to. I also overwrote forward-word-match by putting the following content into $ZDOTDIR/functions/forward-word-match (assuming your $ZDOTDIR/functions directory is in $fpath; otherwise put it into one or modify the $fpath array as well):

emulate -L zsh
setopt extendedglob

autoload match-words-by-style

local curcontext=":zle:$WIDGET" word
local -a matched_words
integer count=${NUMERIC:-1}

if (( count < 0 )); then
    (( NUMERIC = -count ))
    zle ${WIDGET/forward/backward}
    return
fi

while (( count-- )); do

    match-words-by-style

    # For some reason forward-word doesn't work like the other word
    # commands; it skips whitespace only after any matched word
    # characters.

    if [[ -n $matched_words[4] ]]; then
        # just skip the whitespace and the following word
  word=$matched_words[4]$matched_words[5]
    else
        # skip the word but not the trailing whitespace
  word=$matched_words[5]
    fi

    if [[ -n $word ]]; then
  (( CURSOR += ${#word} ))
    else
  return 1
    fi
done

return 0

To get your desired behavior with Emacs keybindings, all I had to do is:

bindkey '\ef' emacs-forward-word

This part of Moriz Bunkus' answer seems to work by itself now, too:

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

It seems to perform even better in some edge cases (e.g. it treats ? as a word boundary while the above does not.)
