Display the Task Info Box (Options, Info Boxes, Task) and the Timing Info Box (Options, Info Boxes, Timing) at the bottom of the screen. Starting by clicking on the first detail task in the schedule, enter the appropriate amount of duration or effort into the Task Info Box. Then edit the Timing Info Box as appropriate, regarding Task Type and Start and/or End dates. (It is preferable to set tasks to ASAP, without entering any dates, as discussed in Task Types and Their Behavior.) Click on the next detail task in the schedule, and again edit the appropriate information in the Task Info and Timing Info boxes.
