If you are using motion tracking then open the Motion Tracking workspace and make sure that you see all of the motion tracking Panel. When you select track motion the options to track scale and rotation will appear as checkboxes. PLEASE, spend some time studying the User Guide and learn to use the Search Help field in the top right corner of After Effects. Don't use the Help Menu, use the Search Help field.
If you are talking about the transform properties then p brings up position and s brings up the scale property as long as the Timeline or the Composition panel are selected.
