To format a paragraph, simply click within the paragraph and click one of the
formatting buttons or select Format -> Paragraph from the
menu. Paragraph formats include headings (remember <H1> tag?),
alignment (left, center, right), indent, and lists.

Lists
To make a list, type in the list items, tapping Enter at the end of
each item. Then select the list items and click the numbered or bulleted
list icons in the menu. Notice how the line spacing changes.
To nest a list item, select it and click the indent button twice.
