This section of the scheduler provides the ability to see Key Dates, Reminders and Tasks that are due that day. As you complete them, you can manually delete them from the scheduler or you can leave them there as past events. If you double click on the Task it will open the task screen from which you can complete the task. The Customization Options allows you to set the maximum height of the section and if you have more events that your height setting, the scheduler will allow you to scroll through the all-day events. You can also decide to see one or all of the three on your calendar. Key Dates just like Reminders and Tasks can be assigned to someone and will be visible on the calendar of whomever it was assigned to. For example, your mother's or your marketing contact's birthdates can show up on your calendar and no one else's. For those key dates that are not assigned to anyone, you can choose to see those as well using the Customization Options.
