Embedded steps, let you go directly to the embedded guide. Similarly, the guide that was embedded can place you in its embedding guide. In the following figure, the embedding guide has a "+" button within it. If you press that button, the embedded guide is displayed.
In the embedded guide, notice the inward pointing arrow at the start step. If you click this button, it displays a dialog containing the guides that embed this guide. Clicking on the link within that dialog takes you to that guide.
