Binding arrow keys in JS/jQuery

Question

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

I've simply combined the best bits from the other answers:

$(document).keydown(function(e){
    switch(e.which) {
        case $.ui.keyCode.LEFT:
        // your code here
        break;

        case $.ui.keyCode.UP:
        // your code here
        break;

        case $.ui.keyCode.RIGHT:
        // your code here
        break;

        case $.ui.keyCode.DOWN:
        // your code here
        break;

        default: return; // allow other keys to be handled
    }

    // prevent default action (eg. page moving up/down)
    // but consider accessibility (eg. user may want to use keys to choose a radio button)
    e.preventDefault();
});
