<style type="text/css" media="screen">
body {

}
textarea {
border: 1px solid #ccc;
display: block;

background: #ececec;
padding: 10px;
margin: 10px 0;

</style>
</head>
<body>
<textarea name="msg" id="msg" placeholder="Your Message" autofocus="true"></textarea>
<button type="submit">Post</button>
<script type="text/javascript" charset="utf-8" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript" charset="utf-8">
$.fn.ctrlEnter = function (btns, fn) {
var thiz = $(this);
btns = $(btns);
function performAction (e) {
fn.call(thiz, e);
};
thiz.bind("keydown", function (e) {
if (e.keyCode === 13 && e.ctrlKey) {
performAction(e);
e.preventDefault();
}
});
btns.bind("click", performAction);
}
$("#msg").ctrlEnter("button", function () {
$("<p class='post'></p>").append(this.val().replace(/\n/g, "<br/>")).fadeIn('slow').prependTo(document.body);
this.val("");
});
</script>
</body>
</html>
