title: On-screen keyboard in Windows Universal App on Windows IoT?
body: <p>Is it possible to show the On-Screen Keyboard (osk) in a Windows Universal App on Windows 10 IoT Core?
  The raspberry pi only has a mouse attached and when I click on a textbox I'd like to show the osk.</p>
  
  <p>I can set the InputScope and IsTextPredictionEnabled but can't figure out how to trigger the osk to show.</p>
