Quickly Resize an Object
You can quickly adjust an object's size without using the scale gizmo by using the 'Grow' and 'Shrink' options in the context menu.
Right-click the object to open the context menu, then select 'Grow' to increase its size or 'Shrink' to decrease it.
Alternatively, you can use keyboard shortcuts to achieve the same result. While holding an object by holding down on it with the left mouse button, use the plus (+) key on your keyboard to increase the object's size, or the minus (-) key to decrease its size.
