You may mark any calendar item (event, to-do or reminder) as new, which causes the item to appear in boldface in your calendar as if you had not yet seen it. This cancels any response or acknowledgment you may have made.

1. In the Day-at-a-Time, click once on the item you wish to mark as new to select it or double-click on the item to display it in its respective editor.
   
   
2. From the Edit menu, choose Mark New.
   
   
3. If you displayed the item in its editor, click Dismiss to close the editor.
