Select the text alignment (left-, center-, right- or full-justified) by highlighting text in your letter and clicking the appropriate icon in this section of the palette. You may also choose single, one and a half, or double line spacing in the same manner.
Paragraph Spacing settings allow you to add space before and/or after a paragraph. Indentation settings allow you to set a first line indention and/or indent the entire paragraph on the left and right.
These same Alignment and Spacing settings can be set in the Paragraph Properties window. Click the Format button at the side of the notice editor window and choose Paragraph… to open the window. Additionally, you may set Tabs on the Paragraph Properties window by specifying them numerically. To set indents and tabs using a ruler, see the Document section below.
