In his post, Jerry asked for a way to obtain something equivalent to >>Del 'x' f_:=Curl[f] I gave him a solution: a notation with Del that is interpreted as Curl. And Jerry is right: in Mathematica "Del" is an operator without no built-in meaning. So, in Jerry private (and possible) world, "Del" can mean whatever he decides it to mean. And, of course, now that I provided a solution, anyone can change it, even without knowing exactly what TemplateBox means.
