The shift key must be pressed continuously, along with a jog key, to initiate a jog motion.

• A. True
• B. False
• C. Only while jogging
• D. Not required

Answer: (A)

Jog operations are guarded by a safety modifier to ensure deliberate action. The shift key serves as that safety control: you must hold it together with a jog direction input to start moving. This design prevents accidental jogs from a single button press and makes the motion intentional. Once you start, you typically continue to hold the shift key through the duration of the jog, and releasing it (or the jog button) stops the motion. So requiring the shift key to be pressed continuously, along with a jog key, to initiate a jog motion is the correct behavior.
