I'm using the following snippet to support blur, focus, keydown, keyup and keypress. Almost all the code comes from the original source code of angular, except that I'm using Array#reduce to avoid creating a named temporary object to store the directives.

.directive( [ 'focus', 'blur', 'keyup', 'keydown', 'keypress' ].reduce( function ( container, name ) {
    var directiveName = 'ng' + name[ 0 ].toUpperCase( ) + name.substr( 1 );

    container[ directiveName ] = [ '$parse', function ( $parse ) {
        return function ( scope, element, attr ) {
            var fn = $parse( attr[ directiveName ] );
            element.bind( name, function ( event ) {
                scope.$apply( function ( ) {
                    fn( scope, {
                        $event : event
                    } );
                } );
            } );
        };
    } ];

    return container;
}, { } ) );
