title: Visual studio code refactoring does not seem to work (e.g. rename symbol - f2)
body: <p>So I have just installed vscode on ubuntu at version: 1.27.2. I have installed the extension for c++ as well.</p>
  
  <p>Its all working nicely, except that I cant seem to use the refactor actions. Specifically I want to use the rename symbol (f2).</p>
  
  <p>When I click a variable and press f2 nothing happens. If I do ctrl+shift+r (refactor actions) I always get "no refactorings available".</p>
  
  <p>I checked the key-bindings and it shows for "f2": </p>
  
  <ul>
  <li><strong>Command:</strong> Rename Symbol</li>
  <li><strong>Keybinding:</strong> F2</li>
  <li><strong>Source:</strong> Default</li>
  <li><strong>When:</strong> editorHasRenameProvider &amp;&amp; editorTextFocus &amp;&amp; !editorReadonly</li>
  </ul>
  
  <p>So I checked that the editor is writeable and text has focus - both true. But I am not sure what this editor has rename provider is?</p>
  
  <p>So I need to install something else? - how can I get refactoring working?</p>
  
  <p><strong>Update</strong></p>
  
  <p>This has now been implemented in <code>vscode-cpptools</code> extension: version <a href="https://github.com/microsoft/vscode-cpptools/releases/tag/0.26.0" rel="noreferrer">v0.26</a> called "rename symbol".</p>
