title: Adding copy & paste functionalities to a custom menu of a webapp
body: <p>We are working on a web application which includes a text editor. It's written in HTML5 + Javascript. </p>
  
  <p>We successfully added a custom menu to our web app, but we have not succeeded in adding copy &amp; paste functionalities as in Google Docs. To our understanding, this can be achieved using Flash which can access the OS clipboard. However, we would like to avoid that technology and use an alternative - I don't think that Google uses Flash either.</p>
  
  <p>Can anybody point us to a valid alternative approach?</p>
  
  <p>Thanks.</p>
