title: How to resolve the javascript error of CKEditor in IE 11
body: <p>My asp.net website uses CKEditor 3.5.3. While it works fine on all other browsers, it gives the following error in IE 11:</p>
  
  <pre><code>JavaScript runtime error: NotSupportedError
  
  N=F.$.createEvent('KeyEvents')
  </code></pre>
  
  <p>It appears that for IE 11, we have to use CKEditor version 4.3.4. I am wondering whether there is any fix for just the javascript error, since I don't want to upgrade for now.</p>
  
  <p>My main reluctance for the upgrade, apart from the time involved is that, the latest version doesn't have a dll to be used by asp.net applications which the older versions had.</p>
