Displays the position of the mouse in world coordinates whenever you are not actively manipulating an object.
When you are transforming an object, the status line displays the pertinent information, depending on the type of transform:
Move: Displays the offset XYZ coordinates based on the current coordinate system. For example, if you’re moving an object and you’re constrained to the X axis, only the X readout will change, displaying the offset of the move along the local X axis.
Rotate: Displays the offset angle in degrees about the axis or axes the rotation is performed around. This is dependent on both the axis coordinate system, and the local/center toggle button.
Scale: Displays the offset XYZ scale in percentages.
You can get the absolute as well as offset information through the Transform-Type-in dialog on the Edit Menu.
