title: Highlighting default option in batch CHOICE command
body: <p>The <a href="http://ss64.com/nt/choice.html" rel="nofollow"><code>choice</code></a> command is often used in batch coding. It has the <code>/n</code> option to hide ChoiceKeys. <a href="http://www.robvanderwoude.com/ansi.php" rel="nofollow">This robvanderwoude.com page</a> explains how to use ANSI sequences to highlight in particular text attributes. But it doesn't give usage examples in real batch code.</p>
  
  <p>So, I ask if it's possible to use an ANSI sequence to highlight a default option in the CHOICE command, i.e. make it bold or underlined, possibly by using a variable message that includes one or all choice letters? Or, maybe a different way exists to accomplish that, except using a (C)apital letter for default choice in its text message?</p>
  
  <pre><code>choice /c ox /n /m "C(o)ntinue or e(x)it?" /t 20 /d o
  </code></pre>
  
  <p>ANSI sequences support <a href="https://msdn.microsoft.com/en-us/library/windows/desktop/mt638032(v=vs.85).aspx" rel="nofollow">is back in Windows 10</a>, but no code usage examples are given by Microsoft.</p>
