Binding arrow keys in JS/jQuery

How do I go about binding a function to left and right arrow keys in Javascript and/or jQuery? I looked at the js-hotkey plugin for jQuery (wraps the built-in bind function to add an argument to recognize specific keys), but it doesn't seem to support arrow keys.

Instead of using return false; as in the examples above, you can use e.preventDefault(); which does the same but is easier to understand and read.

You can use jQuery bind:

$(window).bind('keydown', function(e){
    if (e.keyCode == 37) {
        console.log('left');
    } else if (e.keyCode == 38) {
        console.log('up');
    } else if (e.keyCode == 39) {
        console.log('right');
    } else if (e.keyCode == 40) {
        console.log('down');
    }
});
