title: How to define new keybindings with Visual Studio Code vim extension
body: <p>I've gone over the documentation and the looked at the question:
  <a href="https://stackoverflow.com/questions/37777417/how-to-use-vim-key-bindings-with-visual-studio-code-vim-extension">How to use vim (key-bindings) with Visual Studio Code vim extension</a> and I still can't define new keys in the <code>Vim</code> extension for <code>Visual Studio Code</code>.</p>
  
  <p>I'm trying two things in my <code>settings.json</code>. Trying to delete a full tab - instead of just a single space (like vim does) - with backspace.</p>
  
  <pre><code>"vim.insertModeKeyBindings": [
      {
          "before": "backspace",
          "after": "shift+backspace"
      }
  ]
  </code></pre>
  
  <p>And also to change between editor panes with <code>space, w, w</code> (like using a leader key):</p>
  
  <pre><code>"vim.keybindings": [
      {
          "key": ["space", "w", "w"],
          "command": "workbench.action.navigateEditorGroups",
          "when": "editorFocus"
      }
  ]
  </code></pre>
  
  <p>But I can't get any of those to work.</p>
