Clipboard manager

A clipboard manager is a computer program that adds functionality to an operating system's clipboard. Many clipboards provide only one buffer, overwritten by each new "copy" operation. The main task of a clipboard manager is to store data copied to the clipboard in a way that permits richer use of the data.

Clipboard managers enhance the basic functions of cut, copy, and paste operations with one or more of the following features:

• multiple buffers and the ability to merge, split, and edit their contents
• selecting which buffer "cut" or "copy" operations should store data in
• selecting which buffer(s) "paste" operations should take data from
• handling formatted text, tabular data, data objects, media content, and URLs
• saving copied data to long term storage
• indexing or tagging of clipped data
• searching of saved data

Copy history

Most clipboard managers allow the user to keep multiple clipped objects, available for later use. Some keep a clipping history by automatically making a new buffer for each new cut or copy operation.

Some applications have an internal copy history feature. This has been a standard feature in UNIX editors like vi and emacs for some time. Recent versions of Microsoft Office have included the "Office Clipboard", a built-in clipboard manager, which operates as long as one of the Office suite applications is open.

Clipboard managers in different systems

Windows

The default Microsoft Windows clipboard manager enables pasting the copied data, even after an application is closed, by maintaining the clip buffer itself. Its copying and pasting operations are very versatile in what they permit to be transferred between applications. A range of cells clipped from an Excel sheet can be pasted as a table into MS Word, or OpenOffice.org. Formatted text clipped from a web page will become cells in an Excel sheet, a table in MS Word, or plain text in Text Edit. Windows does not offer a copy history feature. Users wanting this function use a third-party clipboard manager that replaces the default clipboard.

Mac OS X

Mac OS X also has a host of third-party options for clipboard management. Ten of them are presented in a 2009 review article. From this list are:

• ClipMenu free?
• Clipper - dead link March 2011
• Clyppan (commercial)
• JumpCut free
• PTHPasteboard (commercial)
• Savvy Clipboard (commercial)
• iClip - product withdrawn from the market
• Clipboard Evolved (commercial)
• Cute Clips (commercial)
• Stuf (commercial)

Clipboard managers for Mac OS X use the Dock, status bar or Dashboard to integrate with the Mac Look and Feel.

freedesktop.org

The freedesktop.org Clipboard Manager specification describes a protocol layered on top of the ICCCM clipboard spec for client applications. A daemon process is responsible for storing clipboard contents. This daemon clipboard manager must be provided by the window manager running in the user's X session. The client-side specification has native support in a number of toolkits, including GTK+.

X Window System

The UNIX desktop environment KDE ships with Klipper.

GNOME provides a basic clipboard manager function as part of the gnome-control-center (accessed via the gnome-settings-daemon), that supports the freedesktop.org Clipboard Manager Specification. It is also possible to run other clipboard managers in GNOME, such as Klipper, Glipper, Parcellite, clipit or ACM.
