title: Inserting a newline in a multiline zsh command pulled from history
body: <p>Sometimes I use multiline commands in <code>zsh</code>:</p>
  
  <pre><code>❯ echo \
  &gt; a \
  &gt; multiline \
  &gt; command
  </code></pre>
  
  <p>When editing the command after pulling it from a history search, I can change the content of individual lines. However, I can't figure out how to insert another line:</p>
  
  <pre><code># I want to insert another line after "multiline"...
  ❯ echo \
  &gt; a \
  &gt; multiline \  # but hitting &lt;return&gt; here just runs the command, even though there's a backslash at the end of the line
  &gt; command
  </code></pre>
  
  <p>How can I insert a newline in the middle of a multiline command pulled from history?</p>
