Tag reminders on Mac
Tags are keywords you can apply to your reminders to categorise and view them in flexible, creative ways.
You can delete or rename tags, and use them to create Smart Lists. After you create some tags, click one or more of them to see all the reminders that have those tags.
Tags start with the # symbol. To create a multi-word tag, use hyphens or underscores between words. When adding multiple tags, type a space to start a new tag.
Note: All Reminders features described in this guide are available when using updated iCloud reminders. Some features aren’t available when using accounts from other providers.
