title: Disable backspace navigation in browser
body: <p>Does anyone know how to disable the ability to use the "backspace" key on your keyboard to navigate to the previous page you were on?</p>
  
  <p>Right now, I have an invoice type web application, that if the user(on a mac) hits backspace to remove an element within a form field, after reaching the end of the entered item, if they hit the backspace again, it moves to the prior browsed page, making them lose data with the application that was entered.</p>
