In the Gantt view (Window, Gantt) click on the topmost, blank Task Name field. Enter task names, including their heading or summary as the first task in each series, following each task name with the <Enter> key. For example, using the example given in Outline Structure: Summary and Detail Tasks, enter the task names Office Move, Equipment, Cubicles/Desks, Install LAN, Install Wiring, and Setup Servers, just hitting the <Enter> key after each task name. All tasks at this point are at the same indentation level.
