Answer by lfx for How to add keydown/up event listener on eclipse rcp editor view?

I found the way (thanks guys in irc)

// ITextEditor editor;((StyledText)editor.getAdapter(org.eclipse.swt.widgets.Control.class)).addKeyListener(new KeyListener() {    @Override    public void keyReleased(KeyEvent e) {        System.out.println("key released");    }    @Override    public void keyPressed(KeyEvent e) {        System.out.println("key pressed ");    }});
