To accompany some lecture notes I am developing I would like to define a pair of functions of x that could be entered from the keyboard as x^\[UpArrow] and x^\[DownArrow]. The problem is that \[UpArrow] is a binary operator and \[DownArrow] is a letterlike form. Is there a way? I could, of course, use something like superminus and subminus, but I really prefer the arrows.
