title: Turn off autocomplete tab deletion in Intellij
body: <p>Here is an example of an issue I have.
  In Intellij if I am typing in front of String: </p>
  
  <pre><code>private statString foo = "bar";
  </code></pre>
  
  <p>And then I autocomplete static, String will be deleted. 
  Is there a way to change the settings so that the autocomplete does not delete text?  </p>
