SET(CROSS_WINDOW_BOUNDS)

  Determines the effect of CURSOR_VERTICAL on the cursor.  When
  CROSS_WINDOW_BOUNDS is set to ON, the CURSOR_VERTICAL built-in may cause
  the cursor to pass over window boundaries on the screen.  When
  CROSS_WINDOW_BOUNDS is set to OFF, the CURSOR_VERTICAL built-in causes the
  cursor to move only within one window and to obey scrolling regions.

  Syntax

     SET (CROSS_WINDOW_BOUNDS, {OFF | ON})

  Parameters

     OFF        Causes the CURSOR_VERTICAL built-in to move the cursor only
                within one window.

     ON         Allows the CURSOR_VERTICAL built-in to move the cursor over
                window boundaries.  This is the default setting.

  Example

     SET (CROSS_WINDOW_BOUNDS, OFF);

  Prevents the CURSOR_VERTICAL built-in from moving the cursor out of the
  current window.  Instead, text in the window scrolls if the cursor moves
  into a scrolling region.
