Dialogue comes right after Character:
NAK What's up, dead man?
Dialogue can have soft carriage returns, so you can control where line breaks occur:
HAMLET 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.
