Backspace key is reverted in Eclipse Mars

Question

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

Maybe I accidentally used a shortcut key?

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.

Any help appreciated, thank you!

Edit: damn, I just found out that ctrl+x doesn't work any more either!

Got solved:

Go to "Window -> Preferences". Then inside the tree navigate to "General -> Keys".

In the right side of the window, type "Delete" where it says "type filter text".

Find the COMMAND: Delete, BINDING: Backspace and click on UnBind Command button at the bottom. Click Apply, then OK.

Its done.
