Not sure of your comment. Can it be done and if so, how? I can only highlight a single cell at a time. Using the typical keys like shift or ctl and moving the cursor to new points does not work. If it can be done, Wolfram has likely created some arcane undocumented key strokes to do it. Or else there is some undocumented technique for creating groups of cells in the first place that allows it to happen. If so, how?

That's it!!! I would not have found that in a month...which is how long I looked.

Thanks a bunch. BTW, how is that identified in the documentation? and where?

Regards.
