What key combination is used to access the split screen display menu?

The correct choice for accessing the split screen display menu is a combination of the Shift key and the Display key. This particular key combination is designed to enhance user interface functionality within the FANUC CNC system, allowing operators to easily toggle between different display options, including a split screen setup.

Using Shift + Display provides convenient access to the features of the machine's user interface without navigating through numerous menus, thus improving efficiency during operation. This function is particularly useful for operators who need to monitor multiple sets of information at once, such as tooling data and program status, increasing workflow productivity.

Other combinations may refer to different functionalities or be tied to other operations within the system that do not pertain specifically to accessing the split display menu, which reinforces why the Shift + Display combination is integral to this particular action.
