![]() It is also important to realize that according to the selection protocols, nothing is copied until it is pasted. See the Keyboard shortcuts page which lists the default shortcuts in many programs. This prevents inconsistencies in the operation of the selections. ![]() Rather than the old "cut buffers" system where arbitrary applications could modify data stored in the cut buffers, only one application may control or "own" a selection at one time. Despite the naming, all three selections are basically "clipboards". While ICCCM also defines a SECONDARY selection, it does not have a consensually agreed upon purpose. The majority of programs for Xorg, including Qt and GTK applications, follow this behavior. Unlike PRIMARY, it can also handle multiple data formats. Hence, it behaves like the single-clipboard system on Windows. CLIPBOARD Used for explicit copy/paste commands involving keyboard shortcuts or menu items. In some cases, pasting is also possible with a keyboard shortcut. Cut buffers are long deprecated, and although some applications (such as xterm) may have legacy support for them, it is both not likely and not recommended that they be used.į describes the two main selections as follows: PRIMARY Used for the currently selected text, even if it is not explicitly copied, and for middle-mouse-click pasting. ![]() However, they were inefficient and implementation of them varied, so selections were introduced. These were limited buffers that stored arbitrary text and were used by most applications. The clipboard is a facility used for short-term data storage and/or data transfer between documents or applications, via copy and paste operations. Reason: Describe clipboards for Wayland and XWayland. ![]()
