You can italicize text by putting 2 apostrophes on each side.

3 apostrophes will embolden the text.

5 apostrophes will embolden and italicize the text.

(Using 4 apostrophes doesn't do anything special --
the last pair are just ' left over ones' that are included as part of the text.)

A single newline generally has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the diff function (used internally to compare different versions of a page).

But an empty line starts a new paragraph.

When used in a list, a newline does affect the layout (see below).
