Bookmarklet to toggle ContentEditable

ContentEditable Bookmarklet

javascript:(function(e,n,o,t){o=e.body,t=%22true%22==o[n],o[n]=t%3F%22false%22:%22true%22,e.designMode=t%3F%22off%22:%22on%22})(document,%22contentEditable%22)

Human Readable.js

(function () {
  if (document.body.contentEditable === 'true') {
    document.body.contentEditable = 'false';
    document.designMode = 'off';
  } else {
    document.body.contentEditable = 'true';
    document.designMode = 'on';
  }
}())

One Liner.js

(function(d,e,b,s){b=d.body;s=b[e]=='true';b[e]=s?'false':'true';d.designMode=s?'off':'on'}(document,'contentEditable'))

t

cool!

In an old text file, I found:
if (document.designMode=='off') { document.body.contentEditable='true'; document.designMode='on';} else { document.body.contentEditable='false'; document.designMode='off';} void 0;
