title: How do I create a keybinding (Ctrl + O) in Kivy?
body: <p>I'm wanting to create a keybinding in Kivy (Ctrl + O) that I can attach an event to. I see that the Kivy Inspector module is doing something similar but I'm not sure how to replicate the functionality.</p>
  
  <p>I'd like to have the keybinding work on all of the Kivy application so I guess that it must bind to the window/root widget.</p>
  
  <p>Has anyone done this before? Thanks!</p>
