title: How can I suggest multiple lines be changed in markdown
body: <p>I first encountered on GitHub the &quot;suggestion&quot; code block, identified by</p>
  <pre><code>```suggestion
  change
  ```
  </code></pre>
  <p>This offers to replace the line immediately before with what is inside the fence. But what about if I want to replace multiple lines?</p>
  <p>I'd like to think this is possible, but I cannot find documentation of this feature anywhere. I have at least learned that the key terms to use are <a href="https://github.github.com/gfm/#fenced-code-block" rel="noreferrer">fenced code block</a> and <a href="https://github.github.com/gfm/#info-string" rel="noreferrer">info string</a> but the best I can come up with is that the info string (other than the first token) is unspecified.</p>
  <p>Is this capability documented anywhere? It is emminently useful in code reviews.</p>
  <p><strong>Edit: This is a markdown question not a GitHub question</strong></p>
  <p>So far, it appears to be a GitHub-unique feature. That may be the answer, but telling me how to use the GitHub GUI is <strong>not</strong> addressing the question.</p>
