- ShowCellLabel can take the values True or False to show or hide the cell label.
- ShowCellLabel->Automatic works identically to ShowCellLabel->True if the cell had been last evaluated in a currently running kernel session. If the kernel session that last evaluated the cell is no longer running, then Automatic changes the display by obscuring $Line and changing the onscreen style used to display the label.
- ShowCellLabel is more often set for styles of cells than for individual cells.
- If the CellLabelAutoDelete option is set to True or Automatic, the label for a cell is automatically deleted when the cell is modified.
