title: How to view JDK external documentation in IntelliJ IDEA?
body: <p>The shortcut for this action is Shift+F1 but it is always grayed out even though I have pointed JDK <code>documentation path</code> to the <code>docs</code> folder (the docs folder is unzipped from <a href="http://www.oracle.com/technetwork/java/javase/documentation/java-se-7-doc-download-435117.html" rel="nofollow noreferrer">jdk-7u2-apidocs.zip</a> ).<br />
  Thanks</p>
