The Navigation Menu can be opened by selecting the second button in from the left at the top of the screen.
There are a two different options for how to view the Navigation Menu; grid view or list view. The icons to toggle between grid and list view can be found in the upper right corner Navigation Popup.
The Grid View is the default view for verse-based resources, like Bibles and commentaries. This view makes it easy to select a book, chapter and verse.
The List View will automatically appear for resources that are not verse based, like dictionaries, encyclopedias, handbooks, etc. List View can also be used for verse-based resources if you prefer a list with the full names of Bible books.
