I know I can wrap text, but that doesn't work when the first line should be
shorter than the second and/or third.

I know there must be a character out there that drops you down to the next
line. I have been copying & pasting the space between one line and the next
on other people's documents so I can make it work on my documents, but there
must be a key or something people are typing to get that to work. Can someone
fill me in on this secret? It's such a mystery.
