The selected element will be the visible element in other
apps, even if other elements are created later in the
representation, chronologically. To check whether an external view element has already been
specified, select
Tools > External View... again. The dialog box will display the name of the currently
selected element. This also allows you to change elements through
the selection of another element.
Note that you cannot select an
external view element again and that only one element can be selected at
the same time.
