The properties of a text box control.
All controls have properties. Properties determine how a control looks and what it does.
A text box, for example, has properties that can specify its size, allow it to grow or shrink, and provide it with scrollbars.
To display a control’s properties, you would select the control and click the Properties button 
on the Form Design or Report Design toolbar. Related properties are grouped under tabs.
If you clicked a property name or the box next to it, you might see an arrow, and clicking on that would display a list of choices. Or you might see three dots. Those usually mean that Access can help you build a rule for the property, in a dialog box called a builder, which would open if you clicked the dots.
If you clicked a property name or box and then pressed F1, Access would display full information about the property.
Note Before setting properties, make sure you're familiar with the data. Don’t use a tiny text box when people need to enter long names.
