Just as a postscript, it's worth noting the ZLE widgets replace-string
(which can also be loaded under the names replace-pattern or
replace-regexp) and replace-string-again.  This allows you to do this
interactively from the command line.  See the zshcontrib manual page.

I use


# actually autoloaded
zlewidget() {
  # bindkey KEY to new WIDGET, possibly implemented by optional FUNCTION.
  # FUNCTION defaults to WIDGET and will be marked for autoload -Uz.

  local key=$1
  local widget=$2
  local function=${3:-$2}

  autoload -Uz $function
  zle -N $widget $function
  bindkey $key $widget
}
zlewidget "\e%" replace-regexp replace-string
zlewidget '\e&' replace-regexp-again replace-string-again


(though in fact I don't tend to use \e& because (i) I rarely need to
replace the same thing multiple times (ii) I can't remember what the
last thing I replaced is anyway.)
