CTRL+SHIFT+A is an old feature I did not know until the Augi CAD Camp in Paramus NJ. I was introduced to it as if it is a command to undo the grouping feature. When I tried it, it Selected Similar instead. Is it just a ADT 2006 bug, or is there special set up for it? I am holding an Auto Lunch for the rest of my company tomorrow, and I would like to mention this feature if I could figure out the way it works by then.
