Jerry,

>>Del CenterDot f_:=Div[f], .....then I get an error message that Del
>>cannot be followed by CenterDot f

There are many ways to achieve this in Mathematica. Here goes one quick one
(for V 6.0.2 and above). Unfortunately, I don't have time to explain (nor
refine) the code now, but it works. (Use Tab to move through the slot.)

CreatePalette@
 Button["\[Del]\[SelectionPlaceholder]",
  NotebookApply[InputNotebook[],
   TemplateBox[{"\[SelectionPlaceholder]"}, "Curl",
    DisplayFunction -> (RowBox[{"\[Del]", "\[CenterDot]", #}] &)]]]
