portions of your user interface, it is up to you to make sure that parts
of your user interface are not obscured when the keyboard is being
displayed.TouchScreenKeyboard.visible and TouchScreenKeyboard.area should be
used to determine if the keyboard is being shown (activated) and what
portion of the screen is using.
