title: Google Docs Add On onEdit
body: <p>Google Apps has some simple triggers: <a href="https://developers.google.com/apps-script/guides/triggers/" rel="noreferrer">https://developers.google.com/apps-script/guides/triggers/</a></p>
  
  <p>One of which is onEdit. As documented, onEdit fires for Google Spreadsheets, but it does not fire for Google Docs.</p>
  
  <p>Is there a clean way to detect when the user has changed the document, and run a script when that happens?</p>
