clipboard

   <operating system> A temporary memory area, used to transfer
   information within a document being edited or between
   documents or between programs.  The fundamental operations are
   "cut" which moves data from a document to the clipboard,
   "copy" which copies it to the clipboard, and "paste" which
   inserts the clipboard contents into the current document in
   place of the current selection.

   Different {Graphical User Interfaces} vary in how they handle
   the different types of data which a user might want to
   transfer via the clipboard, some (e.g. the {X Window System})
   support only plain text, others (e.g. {NEXTSTEP}) support
   arbitrarily typed data such as images.
