title: How can I use HTML's <kbd> tag on rmarkdown?
body: <p>I have an ioslides presentation on rmarkdown. I would like to use the &#60;kbd&#62; tag to make keyboard looking keys. Is important to note that I want this outside a code chunk. In the document, I have written:</p>
  
  <pre><code>&lt;kbd&gt;CTRL&lt;/kbd&gt; + &lt;kbd&gt;SHIFT&lt;/kbd&gt; + &lt;kbd&gt;ENTER&lt;/kbd&gt;
  </code></pre>
  
  <p>which should look like <kbd>CTRL</kbd> + <kbd>SHIFT</kbd> + <kbd>ENTER</kbd>, but it renders like there are no tags: </p>
  
  <p>CTRL + SHIFT + ENTER</p>
  
  <p>Is there a workaround to use this tag on a rmarkdown document, particularly on an ioslides presentation? </p>
  
  <p>Here is a minimal reproducible example:</p>
  
  <pre><code>---
  output: ioslides_presentation
  ---
  
  ## Keyboard tag problem
  This doesn't render properly:
  &lt;kbd&gt;CTRL&lt;/kbd&gt; + &lt;kbd&gt;SHIFT&lt;/kbd&gt; + &lt;kbd&gt;ENTER&lt;/kbd&gt;
  </code></pre>
