Appointments can be changed and updated in Scheduler for WPF and Silverlight either in-place or through the Appointment dialog box.

1. Use the F2 key to edit the Subject in-place. Press the Enter key to save edited text or Escape key to cancel editing.
2. Double-click an existing appointment to open the Appointment dialog box. Alternatively, use the Enter key to open the Appointment dialog box of the selected appointment.
3. After editing all the desired fields in the dialog use the Save button on the rightmost corner of the Appointment dialog box or Ctrl+S key to update the appointment in the schedule.

You can also move the selection and keyboard focus to the next or previous appointment in the current view by using the Tab (Shift+Tab) key on a selected appointment.
