Click the filter icon at the top right corner of the central pane:
The Filter form will be shown on the right pane.

Status: filters tasks that have the selected status.
Due: filters tasks by due date.
Priority: filters tasks that have the selected priority.

Show completed tasks: filters tasks that are completed. Unchecking this box will show uncompleted tasks.
Depending on the view you select from the left pane such as Task filters, Projects or Labels views, some of the options above may be disabled.
Change any information above. The central pane will reflect instantly to list only the matched tasks.
