title: how to change editor behavior in intellij idea
body: <p>I have installed IntelliJIdea 14.0.2 just now. I do not know its default editor but it is opening my source files in <code>vi</code> option now. So, not letting me do default action like <code>Ctrl + v</code>, <code>Ctrl + d</code> which was present before and I used to like it.</p>
  
  <p>So, how to change this behavior like present in <code>sublime - editors</code>?</p>
