To use anti-aliasing:
1 Select the lasso, polygonal lasso, magnetic lasso, rounded rectangle marquee
(ImageReady), elliptical marquee, or magic wand tool.
2 Select Anti-aliased in the options bar.
To define a feathered edge for a selection tool:
1 Select any of the lasso or marquee tools.
2 Enter a Feather value in the options bar. This value defines the width of the feathered
edge and can range from 1 to 250 pixels.
To define a feathered edge for an existing selection:
1 Choose Select > Feather.
2 Enter a value for the Feather Radius, and click OK.
Note: A small selection made with a large feather radius may be so faint that its edges are
invisible and thus not selectable. If a message appears stating "No pixels are more than
50% selected," either decrease the feather radius or increase the selection's size. Or click OK
to accept the mask at its current setting and create a selection where you cannot see the
edges.

Moving, copying, and pasting selections and layers
You can move or copy selections and layers within or between images—and also between
images in other applications.
Moving selections and layers within an image
The move tool lets you drag a selection or layer to a new location in the image. With the
Info palette open, you can track the exact distance of the move. You can also use the move
tool to align selections and layers and distribute layers within an image.
