+\dd Causes \cw{xcopy} to read or write the clipboard instead of the
+selection. (Modern GNOME and KDE-style programs can often interact

+location which you typically copy things into just by selecting them
+with the mouse, and paste with the middle mouse button. The
+\e{clipboard} is a more Windows-like location which you access using
+explicit Cut, Copy and Paste commands in your application.)
