title: Ctrl 2 refactorings in Eclipse / STS
body: <p>I read on the blogs about Eclipse's quick assist shortcuts and went ahead to try them out, however only 2 out of the 4 work for me.  </p>
  
  <p>When I hit Ctrl+2, STS displays a hint with all 4 of them explained in the right bottom corner: </p>
  
  <ul>
  <li><strong>Ctrl+2, F</strong>  - assign to field</li>
  <li><p><strong>Ctrl+2, L</strong>  - assign to local variable</p></li>
  <li><p><strong>Ctrl+2, M</strong>  - extract method</p></li>
  <li><strong>Ctrl+2, R</strong>  - rename in a file</li>
  </ul>
  
  <p>When I then hit a letter, the expected behavior only works for the last 2 (extract and rename), and not for the first 2 - F and L - to assign to a field or a local variable.  </p>
  
  <p>What am I doing wrong?</p>
  
  <p>Here's what I see in Eclipse's General | Keys Preferences:</p>
