2

Keyboard Arrow Keys for Fine Value Adjustment

Function Description: After focusing on the numerical input box, use the keyboard arrow keys to make precise adjustments.

Application Scenarios: Suitable for size and positioning operations with high precision requirements

3

Hold Shift: Enlarge Value Step by 10 Times

Function Description: Hold down the Shift key while adjusting values to enlarge the adjustment step to 10 times the original.

Application Scenarios: Used for quick large-scale parameter modification, such as overall scaling and scene size adjustment.


Shortcut Operation Tips

1

Shortcut T: Show/Hide Transform Controller

Function Description: Quickly switch the display status of the object's movement, rotation and scaling controller via the shortcut T.
