I created a script for Tampermonkey to edit every Website, now I want to have, that this button right above the caps lock: -->| (on Mac) switches between buttons when I click on it. Currently it puts some spaces between the words, but that's what i don't want. Here's my script:

     // ==UserScript==
// @name         Edit any Website
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @match      *://*/*
// @icon         data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==
// @grant        none
// ==/UserScript==
(function () {
    'use strict';
    // javascript:document.body.contentEditable = 'true' ;
    document.designMode = 'on';

    document.querySelectorAll('a').forEach((a) => {
        a.addEventListener('click', (e) => {
            location = e.currentTarget.href;
        })
    })
    })();

Can someone help me?
