title: Useful Eclipse features?
body: <p>I have been using Eclipse as an IDE for a short amount of time (about 3 months of full use) and almost every day I learn about some shortcut or feature that I had absolutely no idea about.  For instance, just today I learned that <kbd>Ctrl</kbd>+<kbd>3</kbd> was the shortcut for a Quick Access window.</p>
  
  <p>I was wondering what your most useful/favorite Eclipse features are.  With the IDE being so big, it would be helpful to learn about the more commonly used parts of the program.</p>
