I'm making a typing tutor program using javascript. Everything is going well except that if activates browser hotkeys which disrupts the functionality of the program. When I press the single quote in Firefox it triggers "Quick find (links only)" short cut and in all browsers when I press space the page scrolls down a page. Everything is working fine outside of this. Here's the code in the head:

<script type="text/javascript">
$(document).ready(function() {
    executeType();
});
</script>

And the code I am using to capture the keyboard (simplified, but tested):

function executeType() {
    $(document).keydown(function(event) {
           alert(event.keyCode);
    });
}
