How to enter a new line in name of actor

[Lang Du]

Dear Friends,

I have an UML from my friend. I need to correct some actor names. Since some
names are so long, I want to enter name on many lines instead of one line.
How can I enter 'Enter' character ? Could some one give me advice.

Thanks in advance.

Just click an actor, type text. Hit enter key whenever you want a new line.
Is there any other methods ?

Thanks.
