I went through a phase with the Notation package too. It is quite useful, but I recommend just working directly with Format + MakeBoxes and MakeExpression if you're going to change things. Think of the Notation package as a graphical wrapper for defining MakeBoxes/MakeExpression rules via the notebook interface instead of typing everything out. Anyway, you could probably guess how to define the correct MakeExpression rule just from looking at the source code you provided to us. MakeExpression[RowBox[{SuperscriptBox["\[Del]","2"],whatever_String}],_]:= MakeExpression["delSquared"<>whatever] I strongly caution you to stay away from MakeExpression. Just think of the problems WRI has with TraditionalForm input - and they invented the Mathematica box model. Format & MakeBoxes, OOTH, are nice functions for formatting your output.
