Windows Clipboard integration

The X Window System, and thus Cygwin/X, uses its own internal clipboard system that is distinct from the clipboard system used by Windows. Copying and pasting text between these two clipboard systems requires a clipboard integration program that watches for updates to either clipboard and copies data between them when either one is updated.

Cygwin/X has an internal clipboard integration system that is enabled by default. See the Section called Command line parameters in Chapter 3 for more information on the -[no]clipboard command-line parameters.
