When using the area adjust swipe technique, and
the adjustment policy is to balance:
When using the keyboard-based technique,
and the final adjustment point is not within the current selection
region, move (if necessary) the anchor point so that it is at the
end of the current selection region farthest from either the initial
or the final adjustment point. (The use of the final adjustment
point is recommended.)
When using the keyboard-based technique, and the
final adjustment point is within the current selection region, or
when using the mouse-based technique, move (if necessary) the anchor
point so that it is at the end of the current selection region farthest
from the initial adjustment point.
Determine the new selection region to be the area
determined by the new anchor point and the final adjustment point.
Enlarge the new selection region to include the
anchor element or anchor region, if the anchor point is unchanged
and if indicated by the anchor inclusion policy.
Enlarge the new selection region, if indicated by
the end-point inclusion policy, to include the element, if any,
at the final adjustment point.

If the current selection region does not include
an anchor element, or if the anchor element is no longer in the
selection region, identify the anchor element to be the element,
if any, in the region nearest the anchor point.

After a mouse-based area adjust swipe technique
is used, place the active cursor as follows:
If it is a text or graphics cursor,
at the point at which the ADJUST button was released
If the selection region contains one or more elements,
on some element within the selection region
If neither of the above, on the currently cursored
element in the selection scope
