title: Intellij IDEA show javadoc automatically
body: <p>When I am coding at Netbeans it autocompletes the code and show Javadocs. However when I am using Intellij IDEA if I click <strong><kbd>Ctrl</kbd>+<kbd>Space</kbd></strong> I can see the auto-complete and if I click <strong><kbd>Ctrl</kbd>+<kbd>Q</kbd></strong> I can see the javadoc seperately.</p>
  
  <p>Is it possible to see the Javadoc of element whenever I see auto-complete or click <strong><kbd>Ctrl</kbd>+<kbd>Space</kbd></strong> at Intellij IDEA as like Netbeans?</p>
