An ordinal displays the number of an item within a list.
How to use ordinals
Use ordinals to indicate the number of an item in a list, such as a shopping list, series of steps, or instructions. Ordinals also give users the ability to select an item by saying the ordinal number, rather than the item name.
Components of an ordinal
Ordinals change from normal to pressed when selected by voice or touch, and from normal to focused when highlighted by a keyboard or remote, or when Alexa is speaking.
Don’t use ordinals if voice navigation isn’t supported, such as in settings.
Use ordinals only in defined, limited lists. Don’t use ordinals if the list can advance or reverse forever, such as in calendars.
