To rename an alpha or spot channel:

Double-click the channel's name in the Channels palette, and enter a new name. Duplicating channels

You might duplicate an image's channel to make a backup before editing the channel. Or you might duplicate alpha channels to a new image to create a library of selections to load into the current image one by one—thus keeping the file smaller.

If you are duplicating alpha channels between images, the channels must have identical pixel dimensions. (See "Creating new images" on page 73.)

Note: You cannot duplicate a channel to a Bitmap-mode image.
