i have 2 layers, each with a layer mask. i want to copy the complete contents of one layer's layer mask into the other layer's layer mask

alternatively, i could copy the contents of one layer into the other (without affecting the layer masks), as this would have the same result

i've been unable to do either of these, i keep ending up with a new layer

can it be done? how?
(i'm using cs2)

Just CTRL+click on the existing mask and then click the other layer and click add mask.
It even works for gradient masks.

If you're on a mac, just click on the mask icon in the layers palette and drag to the new layer while holding the option key. Control or alt on PC?

i rarely use those buttons at the bottom of the layers window so it took me a while to find the add mask button

thanks very much, it worked fine
