Hi, I would like to know how to go to a new line in a text area when a key combination of Shift+Enter is pressed. (Pressing enter itself causes the text to be cleared and sent off to an ObservableList). Here's what I was trying:

 text.setOnKeyReleased(new EventHandler<KeyEvent>() {
        final KeyCombination comb1 = new KeyCodeCombination(KeyCode.ENTER, KeyCombination.SHIFT_DOWN);
        final KeyCombination comb2 = new KeyCodeCombination(KeyCode.ENTER);

         public void handle(KeyEvent t) {
                if (comb2.match(t) && !comb1.match(t)) {
                        obs.addAll(text.getText());
                        text.clear();
        }
    }
}); 

I'm not aware of any explicit function which allows the caret position to position itself to a new line.
