Which of the following hard keys would bring the menu item ABORT ALL to the TP screen?

The correct choice is the FCTN (function) key, which is designed to access different menu items and functionalities on the Teach Pendant (TP) screen in FANUC systems. Pressing the FCTN key typically opens a menu that allows the user to select various operational commands, including ABORT ALL. This is a crucial function for quickly halting all operations and is easily accessed for emergency or operational clarity.

The other options serve different roles: RESET is generally used to clear alarms or restore a previous state in the system rather than to access specific menu items; LOAD typically relates to loading programs or data into the controller; and STOP is used to pause or stop operations but does not bring up the ABORT ALL option directly. Thus, while all keys have significant functions, the FCTN key is specifically the one that enables navigation to the ABORT ALL menu item.
