Hi, I've been using grouping for a while and never found a way to access my grouped columns. After grouping them with Alt+Shift+Right, one can use Ctrl+0 to "close" (or hide) the newly set up group. Then, one can mouse-click on the plus, or select an overlapping area and pres Ctrl+Shift+0 to show them again.

That's all very useful but how do I access the numbers, which appear in the top left corner. They represent layers of grouped data and I would really love to be able to press a key combo to go from "layer 3" (show all) to "layer 2" (show part of the columns) to "layer 1" (hide all grouped columns).
Hope I explained the question relatively ok and that somebody was as mad to actually come up with a solution for this.

Many thanks in advance,
Slone
