title: How to change the functionality of a button so that it can work as the backspace button
body: <p>Okay, so I have a Compaq laptop [American keyboard].
  It is a few days that the backspace button is broken - I mean, it is totally popped off. It ought to be replaced but it is hard to find it out.</p>
  
  <p>Now, I was wondering whether or not there was a way to change the functionality of another button so that it can replace the functionality of the backspace button. </p>
  
  <p><strong>It is not the DEL button. It is the BACKSPACE button [above the Enter button].</strong> </p>
  
  <p>I knew that through some binary numbers it is possible to change the functionality of a button. For example, I can change the DEL button in the Number Lock so that instead of working as DEL button or dot, it will work as backspace.</p>
  
  <p>Is it possible?</p>
