Vicky, this is what I learned about the planner. Hopefully, it's what you were
asking about.
8.4.1 Making Notes on an Appointment. You can make notes on any appointment
at any time by placing the cursor in the time and title line and pressing
ENTER. From there, simply type your notes. If you have only just scheduled
the appointment, the cursor will already be in the time and title line. When
the notes are complete, you will exit when you press SPACE with E, which will
take you to the top of the day, or any other command such as Scheduling another
appointment, any go to or move commands etc.
