To copy an alias set:
In the Metadata Navigator, right-click the alias set to copy and select Copy.
Right-click the destination folder in the Metadata Navigator and select Paste from the popup menu.
If you are copying to a different folder in the Metadata Navigator, the alias set name is retained.
If you are copying to the same folder, the alias set is automatically renamed for you. For example, an alias set named skuAS is automatically renamed skuAS_copy when copied to the same folder.
