title: How to read values with yq when the key has a dot?
body: <p>I am having issues reading values from a YAML file when there's a dot in the key name.</p>
  <p>i.e.</p>
  <pre><code>a:
   b.c: 2
  </code></pre>
  <p>Reading the <code>a</code> key works fine with <code>cat mytext.yaml | yq r  - a</code>. However, when I tried reading <code>a.b.c</code> it doesn't give any output.</p>
  <p>I tried escaping the dot symbol but that doesn't give any output.</p>
  <p>Anything I am missing here?</p>
