Somebody correct me if I'm wrong as I have not used this in a long time...I think you type a quotation mark before you type and you will get the bubble that stays up longer. It's either that or a hyphen.
ie: "Hello there or 'Hello there <--- I think it's one or the other
Correction - it is a period ----> .
