I am trying to capture when an user presses Ctrl+Enter on his keyboard while being in my application:

class UI(Widget):
 def __init__(self, **kwargs):
 super(UI, self).__init__(**kwargs)
 self._keyboard = Window.request_keyboard(self._keyboard_closed, self)
 self._keyboard.bind(on_key_down=self._on_keyboard_down)

 def _keyboard_closed(self):
 self._keyboard.unbind(on_key_down=self._on_keyboard_down)
 self._keyboard = None

 def _on_keyboard_down(self, keyboard, keycode, text, modifiers):
 if keycode[1] == 'w':
 print("yes")
 return False
 return True


class UIApp(App):
 def build(self):
 return UI()

UIApp().run()

I realize that this code would capture w, but it doesn't even do this. Or at least yes isn't printed to console. My UI:

#:kivy 1.0.9

<UI>:
 title: 'InputDialog'
 auto_dismiss: False

 RelativeLayout:
 ...

python kivy

Check modifiers[0] == 'ctrl' and keycode[0] == 13 or text is None:

def _on_keyboard_down(self, keyboard, keycode, text, modifiers):
 if len(modifiers) > 0 and modifiers[0] == 'ctrl' and keycode[0] == 13: 
 # ctrl + enter pressed
 print("nThe key", keycode, "have been pressed")
 print(" - text is %r" % text)
 print(" - modifiers are %r" % modifiers)
