Here is a terse formulation:

document.onkeydown = function(e) {
    switch (e.keyCode) {
        case 37:
            alert('left');
            break;
        case 38:
            alert('up');
            break;
        case 39:
            alert('right');
            break;
        case 40:
            alert('down');
            break;
    }
};

However, if you are using JQuery, you are better off using e.which, which JQuery "normalizes" to account for cross-browser differences:

$(document).keydown(function(e) {
    switch(e.which) {
        // the rest is the same
