here's a couple of options. jsfiddle: http://jsfiddle.net/a7Rc6/

html:

<a id="one-way">Edit</a>

<a id="another-way" href="#">Edit</a>

javascript:

var value = sel.options[sel.selectedIndex].value; 

// one way:
document.getElementById('one-way').href = 'edittoc.php?key=' + value;

// another way:
document.getElementById('another-way').onclick = function () {
    window.location = 'edittoc.php?key=' + value;
};

Here's an example of href edit, it covers cases where you already have parameters in your link:

function getArticle(sel){
   var value = sel.options[sel.selectedIndex].value;
   $('a[href]').attr('href', function(index, href) {
    var param = "key"=value;

    if (href.charAt(href.length - 1) === '?')
        return href + param;
    else if (href.indexOf('?') > 0)
        return href + '&' + param;
    else
        return href + '?' + param;
});  
}
