This is just a page I'm creating so I can create a subpage for edit testing. I am trying to figure out how to insert a superscript I have seen on some articles that says, for example, "who?" or "where?", challenging the author to provide a reference for an assertion. I tried to use "< r e f text / r e f>" syntax, but "who?" didn't show, only "[1]".
