OpenersNotesSection(Spacer1)Details

Counters can be inserted using the (MenuGrayLink[Insert, paclet:guide/InsertMenu]) ▶ (MenuGrayLink[Automatic Numbering, paclet:ref/menuitem/AutomaticNumbering]) menu item.

With the default setting (RefLink[CounterFunction, paclet:ref/CounterFunction])->(RefLink[Identity, paclet:ref/Identity]), the value of the counter is displayed as an ordinary decimal number.

You can also set the counter display to use symbols such as Roman numerals or Greek letters. Other possible formats include capital Roman numerals, capital Greek letters, lowercase letters, uppercase letters, days of the week, months, and circled numbers. To use any of these formats, choose the corresponding item from the popup menu next to the option.

In the cell expression, these formats are implemented using the (RefLink[CharacterRange, paclet:ref/CharacterRange]) function. This allows you to specify any arbitrary set of symbols or strings to use in the counter display.
