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 before then if no longer needed.
