title: onkeydown in HTML - what key was pressed?
body: <p>A simple question: when I use the <code>onkeydown</code> event in HTML, how can I find out what key was pressed? I'm sure it's really easy, but I've tried googling it; w3schools was no help, and all the other results were people asking about specific browsers. Is there no way which works in all major browsers?</p>
  
  <p>Thanks!</p>
