Which key combination will display a special menu in the FANUC control system?

The correct key combination to display a special menu in the FANUC control system is the combination of the Shift and Coord keys. This specific combination is programmed into the FANUC interface to allow operators quick access to system functions and features that are not immediately visible on the main screen.

In CNC operations, having quick access to special menus can significantly enhance workflow efficiency, as it may provide options for setup changes, parameter adjustments, or operational features that are vital for efficient machine management. The Coord key is specifically relevant to coordinate system manipulation, and when used with the Shift key, it unlocks additional functionalities that aid in more advanced operations.

Other combinations, although plausible, do not specifically correlate with accessing menus within the FANUC environment. Each control system has defined key mappings for efficiency and usability, focusing on the most relevant features for machine operators.
