Ctrl+Enter jQuery in TEXTAREA

Question

How do I trigger something when the cursor is within TEXTAREA and Ctrl+Enter is pressed? Using jQuery. Thanks

This can be extended to a simple-but-flexible JQuery plugin as in:

$.fn.enterKey = function (fnc, mod) {
    return this.each(function () {
        $(this).keypress(function (ev) {
            var keycode = (ev.keyCode ? ev.keyCode : ev.which);
            if ((keycode == '13' || keycode == '10') && (!mod || ev[mod + 'Key'])) {
                fnc.call(this, ev);
            }
        })
    })
}

Thus

$('textarea').enterKey(function() {$(this).closest('form').submit(); }, 'ctrl')

should submit a form when the user presses ctrl-enter with focus on that form's textarea.
