ShowCellLabel

ShowCellLabel
is an option for Cell that specifies whether to display the label for a cell.
  • ShowCellLabel is more often set for styles of cells than for individual cells.
  • With the setting CellLabelAutoDelete->True, the label for a cell is automatically deleted if the cell is modified.
Create one input cell with ShowCellLabel->True and one with ShowCellLabel->False:
Labels are set when the cells are evaluated, but the second input cell's label is hidden:
You can see the label by turning ShowCellLabel on again:
