As with other transformations, rotation occurs around the layer’s anchor point.
To reveal
the Rotation property value for selected layers in the Timeline
panel, press R. The first part of the property value is the number
of whole rotations; the second part is the fractional rotation in
degrees.For information on rotating 3D layers, see Rotate or orient a 3D layer.
. To
constrain rotation to 45° increments, hold down Shift as you drag.
