After creating a number or bullet list, you can change the style by choosing Format, Bullets and Numbering from the menu. Click on the appropriate tab and then choose the style you desire. Finally, click on OK to apply the change. You can force a line break without beginning a new paragraph by using the newline character. This is sometimes useful when working with lists within a hanging-indent paragraph format.
Line spacing is the vertical distance between lines of text.
By default, Word sets line spacing to single line spacing. Other common line spacing settings are 1.5 lines and double spacing. Choose Format, Paragraph. Ensure that the Indents and Spacing tab is selected. From the Line Spacing drop down list, select the desired line spacing.
