ClipboardEvent: clipboardData property

The ClipboardEvent.clipboardData property holds a DataTransfer object, which can be used:

• to specify what data should be put into the clipboard from the cut and copy event handlers, typically with a setData(format, data) call;
• to obtain the data to be pasted from the paste event handler, typically with a getData(format) call.

See the cut, copy, and paste events documentation for more information.
