The basic user interface for inserting linked and embedded objects relies on the familiar Cut, Copy, and Paste commands on the Edit menu, plus one additional command, Paste Special... (and/or Paste Link), for inserting linked objects and for providing additional control over data formats. To accelerate object embedding, client applications should implement the Insert Object command.
Note Paste Special... and Insert Object... are optional but recommended. You should have a good reason to omit them. Paste Links is optional if the preferred Paste Special... is used.
The use of Copy and Paste is not limited to selected document fragments. Entire files may be linked or embedded into documents and displayed as double-clickable icons (that is, packages) with Copy/Paste or by using the drag and drop feature of the File Manager application for Microsoft Windows, version 3.1.
