It’s simple: To add a control, you would click it in the Toolbox and then click the place where you want to add it. To change the size of a control while adding it, you would drag after the second click. Dashed lines would show you the new size.
Easy enough, for a text box or a drawing shape. But many controls need more information to be fully useful. To help you with adding those, Access offers Control Wizards.
You can turn the wizards on (or off) by clicking the Control Wizards button 
in the Toolbox. When the wizards are on, the button has a tinted background. Then if you add a control that has a wizard—not all do—the wizard will step you through a set of questions and choices.
