How to add keydown/up event listener on eclipse rcp editor view?

So I basically need to get key press up/down event from eclipse editor view. I googled it for couple hours but only found keypress events from shell (like in here). But this method do not work in/from editor view.So maybe some one knows how to add keypress event listener in editor?

P.S. I'm using eclipse 4.2.

Thanks in advance
