The top input box shows data in $Address, or adding data to the box will set there attribute.
If a map location is found, the map can be zoomed via the slider control to the right of the map.
Dragging the pop-over will result in a tear-off window that will persist until the end of the current session (i.e. the document and/or app are closed). A torn-off window may be closed during the current session if no longer needed.
From v9.6.0, the map tab has an Open In Maps button that opens the (macOS Apple) Maps application.
