title: How can I find the references of a class, method, variable in Emacs with Etags?
body: <p>I'd like to find all the references to a class, method, variable in Emacs, the same way I'm able to do it in Eclipse with <kbd>Ctrl+Shift+G</kbd> (or <kbd>Cmd+Shift+G</kbd> on the Mac) once I've setup my project's ETags.</p>
  
  <p>I can navigate the code fine, but finding references to things is key to understanding large code bases, I'm sure this must be possible in Emacs but I can't find anything about it, maybe an Emacs expert will know right away.</p>
  
  <p>Thanks.</p>
