The path order
When you are in Edit Path mode, the path you set is shown on the canvas as a thin blue line.
This line, the path, goes from element to element, following the order in which you created the steps. The number in the small blue circle to the left of the steps shows the step number that is currently assigned to this element/frame.
When you click on Present to switch to present mode, this is the order Prezi will use to move forward through your material. Please refer to the image in the How to do it… section of the Setting steps to create a path recipe; the order of your steps is shown by a thin blue line and blue number circles in edit path mode.
