I have watched a number of learning videos and researched this and have even asked some experienced ZB users, but I have never found out what seems like would be a simple question … what are the little icons on the subtools menu used for (besides the obvious one - the eye). So far I have never found anything to occur to my knowledge when I switched between the two closed interlocking circles, the closed and open circles and the interlocking open circles and the knife looking icon. Anyone know?
