From any view where task information is displayed, users can double-click on a task to display the Task Information dialog. This dialog, as the name implies, contains many of the most commonly used properties of a task collected into one dialog and displayed across several tabs to make them easier to find and read. All the fields that are visible in the Task Information dialog are available for display in the normal task views, but the dialog makes them easier to access.
Double-click the task you want to edit to open the Task Information dialog.
Select the General tab (if it is not already selected).
You can edit the task Name, Duration, and Percent Complete fields on this page.
Priority is a field that is used during certain resource leveling operations, which will be covered in Chapter 8, but can also be useful for noting the priority of tasks for your own use during the management of the project. The Priority field is set to 500 by default, but it can be any whole number between 0 and 1,000, with 1,000 being the highest priority.
You can choose to have the Gantt bar for a specific task not appear on the Gantt chart. Check this check box if you want to hide this task from the chart. It will still appear in the sheet on the left side of the view, but the bar will be hidden on the right side.
Project allows users to have the Gantt bars for individual tasks roll up to their summary tasks, so that when a Summary task is collapsed to hide its subtasks, the Gantt bars for the subtasks are superimposed upon the Summary task's Gantt bar. The option to do this is set on a task-by-task basis. This option controls whether the Gantt bar for this task will be rolled up.
