Cut Buffers
Cut buffers are another mechanism to transfer data, in particular selected text. They are window properties of the root window, named CUT_BUFFER1, etc. Unlike selections, cut buffers do not involve a direct interaction between clients. Rather, when text is selected in a window, the window owner copies this text into the property of the root window called CUT_BUFFER1. When the user pastes the text in another window, the window owner reads this property of the root window.
The xcutsel program transfers data between selections and cut buffers, and the xcb program allows various kinds of access to the cut buffers.
Cut buffers are considered obsolete.

Famous quotes containing the word cut:
“The woods were as fresh and full of vegetable life as a lichen in wet weather, and contained many interesting plants; but unless they are of white pine, they are treated with as little respect here as a mildew, and in the other case they are only the more quickly cut down.”
—Henry David Thoreau (1817–1862)
