jQuery Prevent Default Action Function Keys (F3, F4, etc.)

Question

I have this extremely basic example here: http://jsfiddle.net/arhVd/1/

Answer 1

I don't believe you can hi-jack the user's browser.

Answer 2

This seems to work for F3 in IE8:

$(document).keydown(function(event) {
  event.preventDefault();

  if (event.keyCode == 114) { // F3
    // Remap F3 to some other key that the browser doesn't care about
    event.originalEvent.keyCode = 0;
  }
};
