This is a bookmarklet that pop ups a simple text area to let you copy the query paths you get from CRXDE querying.

aem_query_bookmarklet.js

// Author: Brandon Foster
// Purpose: when you query in AEM, you can't copy and paste the paths, 
//				so this takes the paths from the DOM and puts them in a text area so you can copy/paste them
