You can easily create a formatted list with bullets, letters, or numbers.

Simple lists can use a bullet, letter, or number at the beginning of each line:
Ordered lists, such as outlines, can have levels of indented lists within them to show hierarchy. They also use bullets, letters, or numbers at the beginning of each line.
Tiered lists, such as those used in legal documents, are ordered lists that can use different numbering styles for each level.
Click Text
in the toolbar, then click a list style text box, or drag it to the sheet.
Type the first item in your list, then press Return.
Numbers automatically adds a bullet or numbers the subsequent items in the list.
To change the indent level (hierarchy) of an item in the list, do either of the following:
To move the item to the right, press Tab.
To move the item to the left, press Shift-Tab.
When you’re finished, press Return twice to end the list.
You can also select text that you want to format as a list, then choose an option from the Bullets & Lists pop-up menu. If you can’t see the Bullets & Lists pop-up menu, open the Text pane of the Format inspector, then click the Style button.
You can drag items in a list to a different level in the hierarchy or to a different indentation level.
Select the item you want to move by clicking its bullet, number, or letter, then drag it up or down until a blue triangle appears near it.
Drag the item up or down in the list, or drag it to the left or right to change its indentation level.

Select the lines with the bullet you want to change.
In the Text pane of the Format inspector, click the Style button.
Click the Bullets & Lists disclosure triangle, then choose a bullet style from the pop-up menu.

Do either of the following:
For Text Bullets: Click the Bullet pop-up menu, then choose a bullet style (scroll to see all of them).
For Image Bullets: Click the Current Image button, then choose an image bullet.
To use your own image, click Custom Image, then choose the image file on your computer.
You can use other options in the Bullets & Lists section to change the size of the bullets and adjust the amount of space between text and bullets.
You can use numbers, letters, Roman numerals, or a combination to designate levels of hierarchy in an ordered list.
Select the lines with the numbering you want to change.
In the Text pane of the Format inspector, click the Style button.
Click the disclosure triangle next to Bullets & Lists, then choose from the options.
