Should the throttle be released when depressing the clutch to shift gears?

[Gideon]

When depressing the clutch to shift gears while driving, the throttle must be completely released. Detailed explanation: The clutch pedal should be controlled using the ball of the foot. When depressing the clutch pedal, place the ball of your foot on the pedal with your heel touching the ground. When the clutch is fully depressed, keep your knee slightly bent. Precautions: Do not keep your left foot resting on the clutch pedal while driving. Avoid releasing the clutch too quickly or deliberately raising the engine RPM too high, as this will accelerate clutch wear. Always fully depress the clutch pedal before shifting gears. The throttle should be released when depressing the clutch.
