title: VS Code : variables in custom snippet
body: <p>How do I create a custom snippet that will automatically enter a variable's value that I type into its prefix?</p>
  <p>I want a snippet that will create a html start-end tag comment block. For example if I type <code>/se hello</code> I want the result to be</p>
  <pre><code>&lt;!-- $var start--&gt;
  
  &lt;!-- $var end--&gt;
  </code></pre>
  <p>Where <code>$var</code> is replaced with &quot;hello&quot;. Thank you for reading!</p>
