I also take Widow and Orphan control off for the entire document. That way I don't have to remember to remove it when I set up the print template. That is done in the paragraph formatting box by clicking on the Line and Page Break tab, then unchecking Widow and Orphan Control.

as appropriate. Thus, everything remains grouped together in the Documents List, with the Master Copy title at the top.
Kindle won't take hanging indention, but it will take a combination of indented lines and unindented lines (block paragraphs) and I believe it will take built-in before-and-after spacing on paragraphs. However, Smashwords won't; they insist on nothing but centered text and indented paragraphs (no mix of block and indented paragraphs is allowed). Smashwords also won't take built-in before-and-after spacing on paragraphs -- the meat grinder will kick it back at you if you leave some of that in. If you stick to only centered material, indented paragraphs, and line spacing using only paragraph returns, you're safe in all e-books. Be sure to activate the paragraph marks so you can see exactly what you've got, because those rules have to be applied to blank lines as well, and it will also enable you to make sure you've taken out the section breaks. That's important to remember, especially with Smashwords.
