Dim background intensity of the screen
SET HIGHLIGHT ON | OFF | (<expL>)
When HIGHLIGHT is set ON, background intensity of the screen is dimmed when a pop-up is activated. All bold characters on the screen are dimmed while the menu is active, and then restored to their original intensity when the screen is restored. This has been added to distinguish the pop-up object from the screen on which it overlays. If HIGHLIGHT is OFF, bold characters remain bold when a menu or dialog box appears on the screen. By default, HIGHLIGHT is OFF.
