Dialogue comes right after Character:

What's up, dead man?

Dialogue can have soft carriage returns, so you can control where line breaks occur:

The play's the thing
Wherein I'll catch the conscience of the King.

Create the break after "thing" by holding down Shift when you press Return.

If you don't have a keyboard attached, you can delete the empty line between the two lines above, and Slugline will join them into one Dialogue element with a soft break.
