Changing the order or the outline level lines
Click once in a line of text to place the cursor in it, then click on the Outline tab (to the right of the Normal tab) in the Workspace and use the Promote/Demote buttons in the Text Formatting toolbar to move the text to the appropriate position and give it the appropriate outline level.
The button with the arrow pointing left promotes the list entry by one level (for example from Outline 3 to Outline 2), the right arrow button demotes the list entry by one level, the up and down arrow buttons move the list entry. Numbering adjusts automatically.
|| You can also use the Tab key and Shift + Tab keys to promote and demote the outline level of a line in a list.
