Is shifting from second to third gear diagonally upward?

[MacLeo]

Shifting from second to third gear is diagonally upward, but it involves passing through neutral. When shifting from second to third gear, with the clutch pedal depressed, push the gear lever forward. Manual transmission cars use a manual shift mechanical transmission to adjust the vehicle speed, meaning that moving the gear lever changes the gear engagement position inside the transmission, altering the gear ratio to achieve speed variation. The clutch must be depressed to move the gear lever. The corresponding speeds for manual transmission gears are: 1st and 2nd gears correspond to speeds of 5 to 20 kilometers per hour; 2nd and 3rd gears correspond to speeds of 20 to 40 kilometers per hour; 3rd and 4th gears correspond to speeds of 40 to 60 kilometers per hour; and 4th and 5th gears correspond to speeds of 60 to 100 kilometers per hour.
