is an option for objects such as Cell and Notebook that specifies when to automatically display a multiplication symbol between elements separated by whitespace that implies multiplication.

Details

  • AutoMultiplicationSymbol{cond1,…} specifies the conditions under which to automatically display a multiplication symbol.
  • Values for condi include:
  • "Functions"non-numerical functions
    "LineBreaks"hard line breaks that imply multiplication
    "Numbers"numbers and number‐like elements (such as fractions)
    "Symbols"symbols, including % and local variables
  • AutoMultiplicationSymbol{} prevents any automatically displayed multiplication symbols from appearing.
  • The multiplication operator is specified by the NumberMultiplier option. The default value is "∖[Times]".
  • The global setting for AutoMultiplicationSymbol can be changed in the Preferences dialog.
