Snoothing Edges

APDesign said:

ctrl+click the layer you want to [color=black]smooth [/color]to get its selection. Go into the channels, save selection as channel. Deselect if anything is selected, then do a gaussian blur or two (I did 2pixels then 1 pixel, I think, but you can play around here.) once you do that, go to brightness contrast and boost the contrast until you have a nice smooth anti-alias that doesn’t look like a feather (I used mid-eighties here). You can also do what .soulty said and use levels (ctrl+l) here, whatever you are more comfortable with. Now ctrl+click the alpha channel, go back to your layers, and fill.

he says “go back to the layers, and fill” so I click the layers tab and then **fill? **What/where do i go for fill?
