When using a DIV as a container, it NEEDS a tabindex. Select the DIV to start the listening to events.
<h2>Press a button!</h2> <br>
<div id="container" tabindex="1">
<table>
    <tr height="30px">
        <td>Keydown event:</td><td><div id="keydown" class="keyfield">See the key here</div></td>
    </tr>
    <tr height="30px">
        <td>Keyup event:</td><td><div id="keyup" class="keyfield">See the key here</div></td>
    </tr>
</table>
</div>

<script language="JavaScript">
    var keys = keycharm({container:document.getElementById("container"),preventDefault: false});

    keys.bindAll(function(event) {
        document.getElementById('keydown').innerHTML = "Key:" + keys.getKey(event);
    }, 'keydown');
    keys.bindAll(function(event) {
        document.getElementById('keyup').innerHTML = "Key:" + keys.getKey(event);
    }, 'keyup');

    var alertFunction = function() {alert("a!");};
    keys.bind("a", alertFunction);
    keys.unbind("a", alertFunction);
