A tag is a keyword or phrase that you can use to help describe the task. Common uses include:

• Keeping track of the state or progress.
  • Examples: “Step 1”, “Waiting for response”
• Keeping track of the next step.
  • Examples: “Return call”, “Deliver item”
• Classifying the task.
  • Examples: “Meeting”, “Shopping”
• Your own organization scheme.

Unlike folders, contexts, and goals, a task can have more than one tag.
