You can create lists formatted with bullets, numbers, or letters. Any list can use indents to create hierarchy. Tiered lists, such as those used in legal documents, use nested numbers or letters (for example, 3., 3.1., 3.1.1.).
You can use list styles to apply uniform formatting to lists in your presentation. You can create your own list styles and rename existing styles.
Keynote detects when you’re typing a list and adds some basic formatting as you type.
Add a text box to the slide, or place the insertion point in existing text where you want to add a list.
Type a dash, a bullet (Option-8), or a letter or number followed by a period and a space.
For example, 1. or A. followed by a space.
Type the first item in your list and press Return.
Every subsequent item in the list automatically begins with the same character. Numbers and letters are incremented accordingly.
To use a special character for the bullet, choose Edit > Emoji & Symbols (from the Edit menu at the top of your screen), then click a character from a bullet or star menu.
To change the indent level (hierarchy) of an item in the list, click anywhere in the item, then do one of the following:
Move the item to the right: Press Tab.
Move the item to the left: Press Shift-Tab.
To end the list, press Return twice, or press Delete on your keyboard.
If you don’t want Keynote to automatically create lists, choose Keynote > Preferences (from the Keynote menu at the top of your screen). Click Auto-Correction at the top of the preferences window, then deselect the checkbox next to “Automatically detect lists.” The setting applies to all Keynote presentations.
Select the text that you want to format as a list.

When you choose Text Bullets, Image Bullets, or Numbers from the pop-up menu below the disclosure triangle, you see more controls that apply to the type of list you chose.
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.
Drag the item to the left or right, or drag it up or down in the list, until you see a blue triangle where you want the item.
Select the list items with the bullets you want to change.

To use your own text or character for the bullet, double-click the Bullet pop-up menu, then type your own text or character. To use a special character, choose Edit > Special Characters (from the Edit menu at the top of your screen), then choose a character.
For image bullets: Click the Current Image pop-up menu and choose an image bullet style.
To use your own image, click Custom Image, then choose an image file on your computer.

Indent: Type a number or click the arrows next to the Indent fields to set the distance from the left margin to the bullet and from the bullet text to the bullet, respectively.
Change bullet color: Choose a color from the color well (for preset colors that coordinate with the theme) or the color wheel (for any color).
You can’t change the color of image bullets, but you can choose a different image from the Current Image pop-up menu (not shown above).
Adjust bullet size: Type a percentage in the Size field, or click the up and down arrows.
Move bullets above or below the center line of the text: Click the up or down arrows in the Align field.
If you want to apply these changes to other lists in your presentation, you can create a list style, or update the list style you’re already using. Only formatting made in the Bullets & Lists section are included in the list style.
You can create a list style for any kind of hierarchical list, from a simple one that includes just two levels of hierarchy, to a complex one that uses many styles of numbers and letters to define multiple levels.
After you format a level of hierarchy, you update (redefine) the list style to incorporate that level. For example, if your list has five levels of hierarchy, that means you will update your starting style five times to fully define the style. The process results in a single style that automatically formats a list with the same number of levels you defined. You can then use that style for other lists in your presentation.
Click where you want to start the list.
Click the Style button near the top of the sidebar on the right.
If you don’t see a sidebar, or the sidebar doesn’t have a Style button, click in the toolbar, then click Text.
Click the pop-up menu to the right of the Bullets & Lists subhead, then click 
at the top of the List Styles pop-up menu.
Type a name for the new style in the List Styles menu, then press Return.
Type the first item in your list.
Use the controls in the Bullets & Lists section to choose a number or bullet style for this hierarchy level.
An asterisk appears next to the style name in the pop-up window to indicate that you made a change to the style.
Click the pop-up menu next to Bullets & Lists then click the Update button.
Clicking Update changes the format of any existing list items at the same level of hierarchy.
Press Return to go to the next line, then press Tab to indent it.
If the list is in a table cell, pressing Tab moves to the next cell. Instead, in the sidebar, adjust the indent value for the number.
Use the Bullets & Lists controls again to set a number or bullet style, adjust spacing, and make any other format changes.
Click the pop-up menu next to Bullets & Lists, then click the Update button.
Continue formatting each level of hierarchy, clicking the Update button before moving to the next level.
Only formatting changes that you make in the Bullets & Lists section are included in the list style. Changes you make using the controls in the Font section (font, font color, and character styles) aren’t included.
If you have a list style you use frequently, you can create a keyboard shortcut to apply it.
Changing the appearance of a list—by changing the bullet or number style or the spacing of indents, for example—results in style overrides, which are indicated by an asterisk next to the list style name in the List Styles pop-up menu.
If you want to keep the overrides without updating the style, do nothing. The text retains your changes, and an asterisk appears next to the list style name whenever you select or edit the list.
You can also update the list style with your changes, or use the overrides to create a new list style. If you don’t want to keep the overrides, you can revert back to the original list style,
Select the list items with your formatting changes.
Click the Text tab at the top of the sidebar on the right, then click the Style button near the top of the sidebars.
If you don’t see a sidebar, or the sidebar doesn’t have a Text tab, click in the toolbar
If the list is in a text box, table, or shape, first click the Text tab at the top of the sidebar, then click the Style button.

Remove the overrides and revert to the original list style: Click the style name (it has a gray checkmark next to it). The override is cleared, the text reverts to the original style, and the checkmark changes to black.
Update the style to use the overrides: Click the Update button (if there is one), or move the pointer over the style name, click the arrow that appears, then choose Redefine from Selection.
Note: List styles include only the formatting you set using the controls in the Bullets & Lists section of the sidebar. Any formatting you make using the controls in the Font section (font, font color, and character styles) aren’t included in the list style.
Select a list item that uses the style you want to rename or delete.
Click the Text tab at the top of the sidebar on the right, then click the Style button near the top of the sidebar.
