title: suppress an unused variable warning
body: <p>How can I suppress the inspection in Kotlin for an unused variable</p>
  
  <p><code>val xyz = abc</code></p>
  
  <p>I get the squiggly line but <code>ALT-ENTER</code> is useless for this, I tried also to create in another method several variables unused and they also lack the <code>ALT-ENTER</code> ability to ignore the warning. Although I have definitely used <code>ALT-ENTER</code> for this in the past, although maybe it was only in java, can't remember.</p>
  
  <p>So I must manually construct it by hand. I've been trying several variations but I can't get anything to work. Please tell me the correct <code>//noinspection</code> or <code>@SupressWarnings</code> to use, thanks</p>
