Adjustment layers in PS

Here is my problem, i want to be able to use an adjustment layer (like contrast) and apply the adjustment to just one layer, and not everything. Is this possible? THanks

Yes, have the adjustment layer directly above the layer you want to change, hold down alt or cmd(apple) and move the mouse right inbetween the two layers, your mouse will change into a left arrow w/ to circles, click and viola.

ctrl-g. group with previous layer.

thx guys
