🔘This emoji is in the shape of a solid circle and can usually be used to indicate states such as being selected, completed, or determined. For example, in some task lists, questionnaires, option lists and other scenarios, it can be used to mark specific items, indicating that the item has been processed, selected or meets a certain state.
There are a lot of tasks in my to - do list. I will mark a 🔘 in front of the completed tasks.
In this form, the reviewed items can be marked as 🔘.
