Thanks, that's what I supposed too. I almost have it fixed with

    zle set-mark-command

    [ $markset ] && zle kill-region

zle -N my-kill-region
zle -N my-set-mark

bindkey -M emacs '^@'       my-set-mark
bindkey -M emacs '^W'       my-kill-region

But I don't know how to reset markset every newline (other than doing an ugly
bindkey for Return).
