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: Found AngularJS UI and saw their realization of keypress directive.

Open the Global Search app by pressing its shortcut (the default is SUPER + / - Windows key + forward slash).
A global hotkey is a combination of keyboard buttons that execute a command in any application or window, like launching your calculator app for example. It doesn't matter if you're in Word, Excel, in a browser, or on the desktop.
I would say a more proper way (or "Angular way") would be to add it to a directive. Here's a simple one to get you going (just add keypress-events attribute to <body>):
angular.module('myDirectives', []).directive('keypressEvents', [ '$document', '$rootScope', function($document, $rootScope) { return { restrict: 'A', link: function() { $document.bind('keypress', function(e) { console.log('Got keypress:', e.which); $rootScope.$broadcast('keypress', e); $rootScope.$broadcast('keypress:' + e.which, e); }); } }; } ]); In your directive you can then simply do something like this:
module.directive('myDirective', [ function() { return { restrict: 'E', link: function(scope, el, attrs) { scope.keyPressed = 'no press :('; // For listening to a keypress event with a specific code scope.$on('keypress:13', function(onEvent, keypressEvent) { scope.keyPressed = 'Enter'; }); // For listening to all keypress events scope.$on('keypress', function(onEvent, keypressEvent) { if (keypress.which === 120) { scope.keyPressed = 'x'; } else { scope.keyPressed = 'Keycode: ' + keypressEvent.which; } }); }, template: '<h1>{{keyPressed}}</h1>' }; } ]); If you love us?
