I'm beginning to play with blend modes and can use some help. In the adjustment layers, I can walk throught the different blend modes by shift+ and shift-. But these keystrokes don't work in Apply Image. Is there another way to do this? Also in Apply Image, there is no slider for changing the opacity. Other than keying in the percentage, is there an easier way to change the percentage?

I'm not interested in blending two different images, but are interested in blending "good" channels to fix "bad" channels. Dan Margulis did a good job on the theories, but I can use some more precise tutorials. If there are links to using Apply Image or blend modes, please point me to them.

Thanks.
