title: Apply Intellij Code Improvement Suggestions
body: <p>I'm using <a href="https://www.jetbrains.com/idea/" rel="nofollow"><code>Intellij</code></a> for <code>Java</code> development. In the code editor on the right, it displays some yellow markers which indicate issue with my code, e.g. improvement suggestions. When I hover over the affected code line it tell me what to do. Unfortunately I didn't find a way of automatically applying said suggestion. How do I do that? I don't want to do fixes by hand but rather allow <code>Intellij</code> to do them for convenience.</p>
  
  <p><code>CTRL + Space</code> is only code completion.</p>
