How do i add a bullet to a document in pages?

Howdy monnick,

Welcome to Apple Support Communities.

Take a look at the Pages Help link below, it answers the question you asked above about adding bullet points to a Pages document on your MacBook Air.

Format lists - Pages Help

Convert text to a list

1. Select the text that you want to format as a list.
2. Click the Style button near the top of the sidebar on the right.
   If you don’t see the sidebar or it doesn’t have a Style button, click in the toolbar. If the text is in a text box, table, or shape, first click the Text tab at the top of the sidebar, then click the Style button.
3. Click the pop-up menu next to Bullets & Lists and choose a list style.
4. Click the disclosure triangle next to Bullets & Lists to show the list formatting controls.

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.

To use a mix of letters and numbers in a list, select the text you want to format, choose Numbers from the pop-up menu below the disclosure triangle, then choose a letter or number from the last pop-up menu. Click the Tiered Numbers checkbox if you want the numbers and letters nested for each level (for example 1, 1.1, 1.1, and so on).

Cheers,

-Jason
