how to substitute with character < in vim?
<p>For example, I would like to substitute character <strong>[</strong> with <strong>&lt;</strong> for the line below: </p>

<pre><code>inoremap []     []&lt;Left&gt;
</code></pre>

<p>my proposed method from command mode in vim is:</p>

<pre><code>s/[/\%x3c/g
</code></pre>

<p>where <strong>\%x3c</strong> is <strong>&lt;</strong> in ASCII hex but it didn't work.</p>
