You can do the same by simply adding keyress handler on your document. Please provide some more information regarding layout of your page, i.e. how the controls are placed inside the document.

Sir, I think you need to handle onkeydown events for these controls. you can obtain keycode by the code:

JavaScript

var evt = (window.event) ? event : null;
if (evt) {
    var charCode = (evt.charCode) ?
      evt.charCode :
      ((evt.keyCode) ? evt.keyCode :
        ((evt.which) ? evt.which : 0));

}

you can also use this page to test key codes.
