title: Is it possible to hide/remove arbitrary context menu items in Eclipse (3.6)
body: <p>My question can be split into three:</p>
  
  <p>Is it possible to hide/remove arbitrary context menu items in Eclipse (3.6) by ...</p>
  
  <ol>
  <li>standard UI?</li>
  <li>some existing plug-in?</li>
  <li>custom plug-in?</li>
  </ol>
  
  <p>I failed to find ways to do this by methods 1 and 2. If the only option is creating custom plug-in, could anyone push me towards the right direction where to start (I have some experience in Java, but not in Eclipse plug-ins).</p>
