title: Backspace key is reverted in Eclipse Mars
body: <p>My backspace key in Eclipse Mars (4.5.0) works like the delete key: it deletes the right character instead of the left one. That's really confusing</p>
  
  <p>Maybe I accidentally used a shortcut key?</p>
  
  <p>I tried to restart Eclipse but it didn't work. I also tried to switch the key binding preferences to "Emacs" scheme before reverting to "Default" but that didn't work either.</p>
  
  <p>Any help appreciated, thank you!</p>
  
  <p>Edit: damn, I just found out that ctrl+x doesn't work any more either!</p>
