You can also use combinations of these. To begin a bullet list, simply click on the bullet button pictured above. At some point, you will reach the end of your list, but have an extra bullet. You have to click the bullet button again and that extrat dot will go away. I find this quite aggravating, but so far have found no other way to turn it off.
Numbered lists work exactly the same way as bullet lists.
Just click on the number button pictured above and the list will begin. Notice that in Composer, you will not see a number. When you view your page in Navigator, you will see the actual numbers. One nice feature is that you can insert items in the middle of your list and Composer will automatically renumber the entire list for you. Alignment is a royal pain when you are hard coding HTML, but it is as simple as the click of a button with these tools.
