title: Can I reference a Path Variable in Intellij IDEA Run Configuration?
body: <p>In Intellij IDEA 14, I've defined a Path Variable FOO (in Preferences). The IDEA docs are ambiguous about where these variables can be used... Can I reference FOO in a (Tomcat) Run Configuration > VM Options ie:</p>
  
  <pre><code>-DmyProp=$FOO$
  </code></pre>
  
  <p>Also is it $FOO$ or $FOO?</p>
