$updown identifier can be used to return the text in random case eg: $updown(hawkee) can return HaWkeE whereas the $spaces identifers can be used to return the text separated by spaces. eg: $spaces(hawkee) will return h a w k e e u can also use the 2 identifiers at the same time. eg: $spaces($updown(hawkee)) and that may return H a W K E e thats how it works..
