For object-linking (using the traverse object):
Used
when the user presses the Tab key or enters the final character
in a fixed-width field. However, the same chain of next links is
also traversed by the screen reader when reading the form. Defaults
to left-to-right top-to-bottom order.
The chain of next links
can include boilerplate objects, but these objects cannot accept
input focus. Therefore, when advancing focus to the next form object,
tabbing continues until an object that accepts input focus is reached.
You must ensure that the form design does not present a non-terminating
loop.
This property is used only when the container is a subform
or subform set. The link points to the object that gains focus when
the container is entered. In effect the container delegates focus
via this link. Defaults to the first container that is a child of
this container, in top-to-bottom left-to-right order.
