title: Where are Vscode keybind-able command arguments documented?
body: <p>Is there a reference/documentation about it somewhere ?</p>
  <p>E.g.: the <code>workbench.action.quickOpen</code> can be passed a string argument specifying what its base search string should be. I had no clue you could do that. Where would I have found the documentation for something like this and other commands ?</p>
  <pre class="lang-json prettyprint-override"><code>{ &quot;key&quot;: &quot;ctrl+h&quot;, &quot;command&quot;: &quot;workbench.action.quickOpen&quot;, &quot;args&quot;: &quot;hello world&quot; },
  </code></pre>
