What is AngularJS way to create global keyboard shortcuts?

Question

I suppose that I should use directive, but it seems strange to add directive to body, but listen events on document.

What is a proper way to do this?

UPDATE:

Answer 1

Use $document.bind:

function FooCtrl($scope, $document) {
    ...
    $document.bind("keypress", function(event) {
        console.debug(event)
    });
    ...
}
