Blender: Reset position, rotation, size

For example to reset the default view camera to the origin with rotation=0, scale = 1 etc:

ALT G – resets position to (0,0,0) origin (Grab)

ALT R – resets rotation to 0, 0,0 (Rotation)

ALT S – resets scale to 1,1,1 (Scale)

ALT T – resets Tilt to 0,0,0

To reset the cursor:

SHIFT-C= CentreZero View. The 3DCursor is set to zero (0,0,0) and the view is changed so that all Objects, including the 3Dcursor, can be displayed.
