title: How are iOS7 Keyboard Shortcuts Implemented?
body: <p>I saw <a href="http://www.macstories.net/tutorials/a-list-of-new-ios-7-keyboard-shortcuts/" rel="nofollow">this MacStories article</a> about some apps adding keyboard shortcuts to iOS7 apps. How is this implemented? Is it a private API that I shouldn't be using?</p>
  
  <p>I've done some searching around the iOS developer library on <a href="http://developer.apple.com" rel="nofollow">http://developer.apple.com</a>, but I couldn't find anything.</p>
