One of our most popular X-keys. The XK-8 offers eight programmable keys to trigger macros, shortcuts, and applications, select tools or open files or directories. The low profile, slim footprint fits nicely under display monitors or above keyboards. The XK-8 provides a versatile control strip for any computer-driven application.
