Mathematica offers a variety of methods for accessing the system clipboard and clipboard-like operations. In addition to the traditional interactive methods for accessing the system clipboard, the clipboard can be altered and accessed from
Mathematica programs.
— copy the selection to the clipboard
— paste contents, replacing the current selection
— copy the selection to the clipboard in a plain text form which fully preserves evaluation semantics
— copy the selection to the clipboard in a plain text form which preserves the onscreen appearance at the expense of evaluation semantics
CopyToClipboard — copy an object or selection to the system clipboard
Paste — paste an object to the present selection, possibly from the system clipboard
