When creating or editing a message, you have a number of options available to you that affect only the current message you are working on.
To edit a previous message, select the message from the Playback List.
To create a new message, press the New button located at the bottom right of the Scheduler Interface.
When you create a new message, it will inherit all the display properties of the previously displayed message. If you would like the display properties returned to the Switchboard Scheduler default settings, press the Default button located at the bottom right of the Scheduler Interface.
