Copy and Paste
Select elements in Structure , use Ctrl/Cmd + C or Copy, select a compatible destination, then Ctrl/Cmd + V or Paste and save. Containers include children; supported multiselections copy together. Copies are independent, unlike shared Global Blocks.

Properties Only
Copy a compatible element, right-click the target, and choose Paste Design or Paste Settings. These replace that group without inserting an element; Design preserves content.
Right-click a section heading for Copy Typography / Paste Typography or corresponding group actions. Clear removes its values.

Whole Layout and Transfer
Use Structure's header menu Copy All Elements, save/switch documents, then Paste Elements.

Compatible cross-site clipboard transfer requires referenced media, dynamic sources, plugins, variables, presets, and blocks; it is not full migration. Destination layout/globals may change appearance.
If prompted, complete Enable Paste or clipboard permission, then copy again. Incompatible source/target disables property pasting.
