title: WPF Bind button to key pressed
body: <p>I have not done WPF development before. </p>
  
  <p>I am creating a calculator. I want the "one" button to be bound to the keyboard key "1".
  So the click function of my button must execute when the keyboard key "1" is pressed.</p>
  
  <p>Please advise on how to do this></p>
