You can enter type that flows along the edge of a work path created by a pen or a shape tool.
When you enter type along a path, the type flows in the direction that anchor points were added to the path. Entering horizontal type on a path results in letters that are perpendicular to the baseline. Entering vertical type on a path results in text orientation parallel to the baseline.
As you move a path or change its shape, the type conforms to the new path location or shape.
To move text, click and drag the type along the path. Be careful not to drag across the path.
To flip text to the other side of the path, click and drag the type across the path.
