The option ShowCellLabel determineswhether such labels should be displayed. CellLabelAutoDelete determines whether the labelon a cell should be removed if the contents of the cell are modified. Doing this ensures thatIn@nD := and Out@nD = labels are only associated with unmodified pieces of kernel input andoutput.Cell tags are typically used to associate keywords or other attributes with cells, that can besearched for using functions like NotebookFind. Destinations for hyperlinks in Mathematicanotebooks are usually implemented using cell tags.The option ConversionRules allows you to give a list containing entries such as "TeX" -> datawhich specify how the contents of a cell should be converted to external formats. This is particularlyrelevant if you want to keep a copy of the original form of a cell that has been converted inMathematica notebook format from some external format.
