Use the Pointer dialog and explore the image with the mouse (IRL I keep the Pointer dialog docked in my controls window, because I use it all the time). Keep Sample merged unchecked if you want the opacity of the current layer.

Thanks This was not a "dock" I just had checked out.
And Its better than nothing - But its "follow-up inspection"
There is no way I can tell Gimp "for here to here I want the opacity to go form x-vallue to y-vallue"  for example ?
