`MAP-NODES` illustrates how to combine recursive paths with `continue-then-stay`, which navigates to the provided path and then to the current element. This should also point to how you might use recursive paths with `stay-then-continue`, which navigates to the current element and then to the provided path. `MAP-NODES` illustrates how to combine recursive paths with `[continue-then-stay](https://github.com/nathanmarz/specter/wiki/List-of-Navigators#continue-then-stay)`, which navigates to the provided path and then to the current element.
