Final answer:
The Combo Box Wizard or List Box tool on the Design tab in Microsoft Access is used for creating a list of values for the control. It offers the option to either manually input values or to specify a table or query as the source.
Step-by-step explanation:
The tool on the Design tab that is used to create a list of values for the control by typing values or specifying a table or query as the source is known as the Combo Box Wizard or the List Box tool in Microsoft Access. When creating a form or report, you can insert a Combo Box or List Box control to present a list of items that users can select from.
The Wizard helps you through the process of setting up the control. You can manually type in the values you want to display in the list or you can choose a table or query from your database as the source for these values. This makes it easy to create dynamic lists that are updated automatically whenever the underlying table or query changes.
