title: Is there a way to enable Visual-Assist-style tooltips for comments with IntelliJ IDEA?
body: <p>One thing that I've found incredibly useful, especially when working with code that I haven't written myself, is when tooltips can show me the comments, and syntax highlighting for a given variable/value/function/method/etc. It wastes time having to go to the implementation itself to read the comments and then come back.</p>
  
  <p>Visual Assist X for Visual Studio does this, here's an example I found:
  <img src="https://i.stack.imgur.com/H2Tgg.png" alt="Visual Assist Tooltip"></p>
  
  <p>Notice the comments at the bottom of the image, and syntax highlighting applied to the tooltip itself.</p>
  
  <p>I'm hoping IntelliJ IDEA does this, or at least that a plugin for it does. Any help is much appreciated.</p>
  
  <p>Background info: I'm using IntelliJ IDEA 11, particularly for Scala.</p>
