Rotate the selected object on any axis. The rotation is snapped to a defined angle. You can change the angle on the bottom right.
You can also press and hold the ctrl key and drag to rotate without any snapping.
Scale Tool

Pivot Tool

Change the center pivot point of an object. Can be useful to translate for example a 90 degree tunnel. This is a temporary change, unless you use 'Set Origin To Pivot'.
