Shows a manipulator tailored for the selected node or attribute.
Snapping is available for commands that use the Show Manipulator Tool; for example:
Snapping occurs when you move freely as well as when you move along an axis; this can be very helpful when positioning lights and cameras in orthographic views.
For those tools that support it, you now have the following snapping options ( Window > Settings/Preferences > Tool Settings):
Sets spacing relative to the current position while rotating. That is, if the current position is 10 degrees, step size is 15 degrees and Relative is on, you snap to 25, 40, 55, and so on. If Relative is off and step size is 15, you snap to 15, 30, 45, and so on. Only selectable if Snap Rotate is on.
