 358  *  1. On keydown with paste keys Ctrl+V or Shift+Insert create
 359  *     a paste bin element and move focus to that element.
 360  *  2. Wait for the browser to fire a "paste" event and get the contents out of the paste bin.
 361  *  3. Check if the paste was successful if true, process the HTML.
 362  *  (4). If the paste was unsuccessful use IE execCommand, Clipboard API, document.dataTransfer old WebKit API etc.
