http://www.missyuan.com/thread-350765-1-1.html after selecting multiple layers, click the link button below the Layer palette (the red arrow), The link to the selected layer is implemented by linking to each other. Select the new layer and any linked layers to unlink the layer by selecting the layer in the link, click the link button below the Layer palette. Allow links to be lifted when multiple layers are selected and some of the remaining layers automatically follow Photoshop to allow multiple sets of links to exist at the same time. For example, eye can be a set of links with eye copies. At the same time, nose and face can be made into a different set of links. Nonetheless, a layer can only exist in a set of connections, such as the eye layer, which cannot be linked to a face layer while forming another set of links with the nose layer. If you do this, the newly established link relationship will replace the old ones.
5-5 links to layers-new versions are not used
