title: How to make IntelliJ IDEA's Auto Pop-Up Documentation appear every time?
body: <p>In IntelliJ IDEA, if you type a variable and then hit the period "." button, you get a list of possible members to choose from. If you press Ctrl+Space, you get a documentation window containing further explanations of each member.</p>
  
  <p>As a learner, <strong>I want to make this extended documentation pop-up automatically every time</strong>. For example, if I'm programming in Java and I type:</p>
  
  <pre><code>System.
  </code></pre>
  
  <p>I want the documentation window to pop-up every time I select a member, without having to press Ctrl+Space. If you've used Visual Studio to program in C# I think you'll know what I mean.</p>
  
  <p>Going into File->Settings->Editor->Code Completion and changing the autopopup documentation timers did not help.</p>
  
  <p>Visual Studio 2010 implements intellisense extremely well, in my opinion.</p>
