To clarify Sjosz's post and help a little further: Movement is a red, green and blue widget with arrows on each of the three axes, rotational widget is a circular version on three axes, and the universal scaling widget is a red widget with three axes. Pressing spacebar will cycle through these three. There is, however, a local scaling widget which has the same appearance as the universal scaling widget, but will have the three colors associated with the XYZ axes.
