Each field in the Properties window has two sections: the property’s name and the property's value:
 

The name of a property is represented on the left column. This is the official name of the property. The names of properties are in one word. You can use this same name to access the property in code.

The box on the right side of each property name represents the value of the property that you can set for an object. There are various kinds of fields you will use to set the properties. To know what particular kind a field is, you can click its name. To set or change a property, you use the box on the right side of the property’s name: the property's value, also referred to as the field's value.

• To display the Properties windows, on the main menu, click View -> Properties Window

By default, these fields have nothing in their value section. Most of these properties are dependent on other settings of your program. For example, you can set a menu property for a form only after you have created a menu. To set the property on such a field, you can type in it or select from a list.

• Click the body of the form.
  In the Properties windows, notice that the AccessibleName and the Tag fields are empty

Some of the properties are numeric based, such as the Location or the Size. With such a property, you can click its name and type two numeric values separated by a comma. Some other properties are created from an enumeration or a class. If you expand such a field, it would display various options. Here is an example from the Font property:
