A friend who's making the transition from Photoshop CS2 to Photoshop CS recently wrote with this question:
In CS I often add an adjustment layer and then hit Command + G to group it with the layer immediately beneath it.  Now in CS2 I hit Command + G and I'm into the whole new Grouping thing, which is not what I'm  trying to do. Can you tell me how to do the old-fashioned grouping that was accomplished in CS by Command + G?
The answer after the jump.

It sounds like you’re trying to make a Clipping Mask to limit the effect of the adjustment layer to the layer just beneath it. It’s true that Command+G (Mac)/Contol+G (PC) has been co-opted for creating a layer group. But there’s another quick way to make a Clipping Mask in CS or CS2. Hold the Option key (Mac) or Alt key (PC) as you move your mouse over the border between the adjustment layer and the underlying layer. When the cursor changes to a double-circle, release your mouse. Those two layers are now joined together in a Clipping Mask, as indicated by the hooked arrow and indent on the adjustment layer and the underline on the base layer.
