Hi evereybody,

You can not have a function that acts like you are pressing the arrow keys, but I am assuming that you want the page to scroll?

If I am corrct with my assumption, then you can use the window.scrollBy() or window.scrollTo() menthods.

You can learn more about them here:

OR

Do you want to detect a keypress of the arrows after the page has loaded?

I think this should do it, you should replace the formName and also the radiobutton name with the correct values. I did not test this out to see if it works, I am not sure if it will. lol... Yell if it doesn't!

<script>
 function handleKeyPress(evt) {
  var nbr;
  if (window.Event) nbr = evt.which;
  else nbr = event.keyCode;
  var lastOne = document.formName.radioButtonName.length;
  if(nbr==38)document.formName.radioButtonName[0].focus();
  else if(nbr==40)document.formName.radioButtonName[lastOne-1].focus();
  else {}
  }
 document.onkeydown= handleKeyPress
</script>
