Look at the compass rose in the lower right corner. When there&#x27;s another detail slide below, the down arrow is dark. If you&#x27;re at the bottom, it&#x27;s grey. Basically you&#x27;re navigating a grid and the arrows tell you if the cell in that direction is populated or empty.<p>I&#x27;m not totally sure if moving sideways pops you back up to the top row (which it should) or to the equivalent depth of the neighboring stack.<p>I actually really like this style. It allows you to quickly skip across the top row to get the main points, then dive deeper when needed.
