Note that the first two methods may also cause the Roles & Goals window, Tasks window, and the Inspector panel to all be opened if they are not open already. Which windows are opened is determined by a preference.
If an appointment was typed directly into a schedule, it won't have a task associated with it. In that case, the first two methods will have no effect, but using the third method will attach the appointment to the goal currently selected in the Roles & Goals window. For more information on attaching appointments to goals, see the next section.
