I would like to have a button on my site which simulates `CTRL` + `+` (zoom-in). So I need to create 2 keypresses or something. I have the folowing which fires 1 keypress:

```
<html>
<head>
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.4.min.js"></script>
    <title>Stackoverflow</title>
</head>
<body>
<script type="text/javascript">
    function simulateKeyPress(character) {
        jQuery.event.trigger({ type: 'keypress', which: character.charCodeAt(0) });
    }

    function pressCtrlPlus() {
        simulateKeyPress("=");
    }

    $(function () {
        $('body').keypress(function (e) {
            alert(e.which);
        });
    });
</script>

<input type="button" value="Ctrl +" ONCLICK="pressCtrlPlus();">

</body>
</html>

```

Does somebody know how to create a `CTRL` + `+` event by clicking on a button?
