You can perform various operations on a task in the workflow tree by right-clicking the task in the tree and using the context menu to:
Add new tasks to the workflow by choosing Insert Next Task. The available tasks that can be inserted are arranged by what is recommended.
Group tasks together by selecting them and choosing Create Group.
Complete, or execute, a task by choosing Update.
Delete a task by choosing Delete.
Rename a task by choosing Rename.
The ability to automatically
display a task's objects in the graphics window (such as mesh elements, facets, etc.) is
disabled for larger models when using the Fault-tolerant Meshing
workflow, depending on the Task based display preference setting (see
Setting Preferences for Workflows). If a task has a particular display
available, you can display objects for that task in the graphics window by hovering over the
task in the workflow tree and selecting the 
icon that appears. This is useful to
quickly visualize a task's objects without having to explicitly visit the task details.
