Notation Package
The Notation Package allows you to extend the Wolfram Language so it understands and functions correctly with new typeset notations. Typically, new notations are defined by constructing explicit MakeExpression and MakeBoxes rules. The Notation Package provides functionality for introducing new notations easily, intuitively, and graphically.
Defining Notations
Notation — create a custom notation for input and output
Symbolize — force a box structure to be treated as a single symbol
InfixNotation — force a box structure to be treated as an infix operator
Removing Defined Notations
RemoveNotation — remove a custom notation
RemoveSymbolize — remove the symbolization of a box structure
RemoveInfixNotation — remove the definition of a custom infix operator
ClearNotations — clear all custom notations, symbolizations, and infix operators
Input Aliases
AddInputAlias — add an alias in the current notebook
ActiveInputAliases — list of active aliases in a notebook
UpdateNotebookStyles — add the custom style and input alias notations to a notebook
