+'''Keybinding
+==========
+
+This module forces the mapping of some keys to functions:
+
+* F11: Rotate the Window through 0, 90, 180 and 270 degrees
+* Shift + F11: Switches between portrait and landscape on desktops
+* F12: Take a screenshot
+
+Note: this doesn't work if the application requests the keyboard beforehand.
+
+Usage
+-----
+
+For normal module usage, please see the :mod:`~kivy.modules` documentation.
+
+The Keybinding module, however, can also be imported and used just
+like a normal python module. This has the added advantage of being
+able to activate and deactivate the module programmatically::
+
+    from kivy.app import App
+    from kivy.uix.button import Button
+    from kivy.modules import keybinding
+    from kivy.core.window import Window
+
+    class Demo(App):
+
+        def build(self):
+            button = Button(text="Hello")
+            keybinding.start(Window, button)
+            return button
+
+    Demo().run()
+
+To remove the Keybinding, you can do the following::
+
+    Keybinding.stop(Window, button)
+

+from kivy.utils import platform
+
+__all__ = ('start', 'stop')

+def _on_keyboard_handler(instance, key, scancode, codepoint, modifiers):
+    if key == 293 and modifiers == []:  # F12
+        instance.screenshot()
+    elif key == 292 and modifiers == []:  # F11
+        instance.rotation += 90
+    elif key == 292 and modifiers == ['shift']:  # Shift + F11
+        if platform in ('win', 'linux', 'macosx'):
+            instance.rotation = 0
+            w, h = instance.size
+            w, h = h, w
+            instance.size = (w, h)
+
+
+def start(win, ctx):
+    win.bind(on_keyboard=_on_keyboard_handler)
+
+
+def stop(win, ctx):
+    win.unbind(on_keyboard=_on_keyboard_handler)
