Unite multiple x copy paste buffers
X servers use two schemes to copy text between applications. The first one (old and deprecated) is the cutbuffer. It is a simple buffer in which any application can store text. The other scheme is the selection and works differently. There may be many selections in a single server. An application does not copy data in a selection, it 'owns' it. When another application wants to retreive the content of a selection, it asks the owner. Recent desktop applications (GNOME, KDE, ...) use two selections: the PRIMARY and the CLIPBOARD. The PRIMARY selection is used when you select some text with the mouse. You usually paste it using the middle button. The CLIPBOARD selection is used when you copy text by using, for example, the Edit/Copy menu. You may paste it using the Edit/Paste menu.
