Cutting, copying, and pasting library icons

Cut, copy, and paste icons in the Library window the same way you do in the Design window:

Cutting a library icon cuts only the icon and retains its links. Deleting a library icon breaks any links it has.
Copying a library icon copies only the icon and not any links. Copying doesn't change links in the original icon.
When you paste more than one icon into a library file, the icons are pasted individually. Icons linked to a library can't be pasted into a library.
