Change of Anchor Point to Extended Selection

      This article describes a method of extended selection that
automatically changes an anchor point if necessary according to a
current selection and a current cursor position.

      Fig. 1 shows the relation between a current selection and a
current cursor position.  The new anchor point is classified into
four groups corresponding to the current selection and the current
cursor position.  If the current cursor position is on left upper
side of the current selection, the new anchor point is the right
lower corner of the current selection (Fig. 2-1).  If the current
cursor position is on right upper side of the current selection, the
new anchor point is the left lower corner of the current selection
(Fig. 2-2).  If the current cursor position is on left lower side of
the current selection, the new anchor point is the right upper corner
of the current selection (Fig. 2-3).  If the current cursor position
is on right lower side of the current selection, the new anchor point
is the left upper corner of the current selection (Fig. 2-4).

      If the current selection is a multiple line selection, the new
anchor point is the top line or the bottom line of the current
selection.  If the current selection is a multiple column selection,
the new anchor point is the left column or the right column of the
current selection.
