CellID

✖

is an option for Cell that specifies a unique ID number for a cell.

Details

  • Typically, a CellID will be created automatically by the system for each new cell inserted in a notebook that has the setting CreateCellID->True.
  • When CellID is managed by the Wolfram System, its value is guaranteed to be unique in a given notebook. It is possible for a CellID to be set by hand, but its uniqueness will no longer be guaranteed.

Examples
