Hook menu - title arguments
You can use single title callback by passing two arguments :

'title arguments' =&gt; array(3, 4),


and use same callback for both function :

function fr_form_view_submission_page_title($id, $type = 'view') {
  $type = ucfirst($type);
  return t('@type submission ID: @id', array('@type' =&gt; $type, '@id' =&gt; $id));
}
