Although the easiest way to add a text box is by using the Field Menu, you can add text boxes without using the menu. This is the method you use when you want to add a calculated text box, that is, a text box that is used to display a calculated value.
To add a text box without using the field menu
Open the form in the Form Designer.
Open the Toolbox and select the Text Box tool.
Move the cursor into the design area.
Click to add a text box of the default size, or click and drag to create a text box with a different size.
