How can I use two custom fields in WP Query

I solved with this

$args = array(
'posts_per_page'        => 6,
'post_type'         => 'post',
'post_status'       => 'future',
'meta_key'          => 'listorder',
'order'             => 'ASC',
'orderby'           =>  'meta_value_num',
'meta_query'        => array(
                        array(
                            'key' => 'edition',
                            'value' => 1,
                         ),
                        ),
);
