• CellEvaluationDuplicate is an option for Cell which specifies whether the front end should make a copy of the cell before performing any evaluation of its contents that you request.
• New cells generated when CellEvaluationDuplicate->True
have styles specified by the setting for DefaultDuplicateCellStyle
for the notebook.
• CellEvaluationDuplicate is typically set for styles of cells rather than for individual cells.
