title: regex to match character in specific position
body: <p>I need to come up with a regex to look for only letters A, F or E on the position 9 of a given text. I am really new with regex, did some searching and couldn't find any similar response. what i have so far is:</p>
  
  <pre><code>/^.{9}A/
  </code></pre>
  
  <p>This command seems to work to find letter A on the space nine, but how can I add the other 2 letters to the regex? </p>
