Exit Point Mode
In
Exit Point Mode
, a touch is reported only when a stylus leaves the
active area of the touch screen. The tracking box jumps to the point

the screen to generate another touch. A touch is not reported when a
stylus enters or moves about the active area of the touch screen. To use

If you add an Exit Point Modifier, touch coordinates are reported
whenever a stylus leaves the active area of the touch screen, in addition

active. For example, in
Enter Point Mode
with the modifier added, touch
coordinates are reported whenever a stylus enters the screen (
Enter Point
Mode
) and leaves the screen (Exit Point Modifier).
