title: Indenting multilines/block with vscode and vim plugin
body: <p><a href="https://stackoverflow.com/questions/49572646/un-indenting-lines-in-vs-code">This</a> is already on the site, but it doesn't work for me.  I'm not 100% sure the answer is responsive to my situation (the question asks about vim "mode").  If it is, the context for the accepted answer isn't obvious for me.</p>
  
  <p>I assume were supposed to splice the json fragment</p>
  
  <pre><code>{
    "key": "shift+tab",
    "command": "outdent",
    "when": "editorTextFocus &amp;&amp; !editorReadonly &amp;&amp; !editorTabMovesFocus"
  }
  </code></pre>
  
  <p>into our settings but it's not clear how or where.  The app has a settings.json, a keybindings.json and the plugin has package.json.</p>
  
  <p>I got this to work in vim itself a year or so ago IIRC, but it took a plugin and a couple of settings.</p>
  
  <p>Edit to add: ctrl+[ and ctrl+] aren't functional for me.  Presumably they would be w/o the vim plugin, but the plugin overrides the ctrl commands.</p>
