I would like to be able to create a multiple line Subject Heading for
calendar appointments, yet I cannot find a setting to allow me to do this.  
As an example, I would like to type-in a couple words for the appointment,
then hit "Enter" to create a new line in the subject heading without opening
the full appointment window.  Of course Outlook will spill overflow
subject-text down to another line, but I would like to create these new lines
uniformly.

Any help would be much apprectiated!
