In human-computer interaction, cut and paste and copy and paste are related commands that offer a user-interface interaction technique for transferring text, data, files or objects from a source to a destination. Most ubiquitously, users require the ability to cut and paste sections of plain text. The cut command removes the selected datafrom its original position, while the copy command creates a duplicate; in both cases the selected data is placed in a clipboard. The data in the clipboard is later inserted in the position where the paste command is issued.

The command names are an interface metaphor based on the physical procedure used in manuscript editing to create a page layout.

This interaction technique has closeassociations with related techniques in graphical user interfaces that use pointing devices such as a computer mouse (by drag and drop, for example).

[edit]History

The term "cut and paste" comes from the traditional practice in manuscript-editings whereby people would literally cut paragraphs from a page with scissors and physically paste them onto another page. This practice remained standard as late as the 1970s. Stationery stores formerly sold "editing scissors" with blades long enough to cut an 8½"-wide page. The advent of photocopiers made thepractice easier and more flexible.

The act of copying/transferring text from one part of a computer-based document ("buffer") to a different location within the same or different computer-based document was a part of the earliest on-line computer editors. As soon as computer data entry moved from punch-cards to online files (in the mid/late 1960s) there were "commands" for accomplishing thisoperation. This mechanism was often used to transfer frequently-used commands or text snippets from additional buffers into the document, as was the case with the QED editor.[1]

The earliest editors, since they were designed for "hard-copy" terminals, provided keyboard commands to delineate contiguous regions of text, remove such regions, or move them to some other location in the file. Sincemoving a region of text required first removing it from its initial location and then inserting it into its new location various schemes had to be invented to allow for this multi-step process to be specified by the user.

Often this was done by the provision of a 'move' command, but some text editors required that the text be first put into some temporary location (AKA, "the clipboard") for laterretrieval/placement.

Although the mechanism was already in widespread use in early line and character editors, Lawrence G. Tesler (Larry Tesler) popularized "cut and paste" in the context of computer-based text-editing while working at Xerox Corporation Palo Alto Research Center (PARC) in 1974–1975.[2]

Apple Computer widely popularized the computer-based cut-and-paste paradigm through theLisa (1983) and Macintosh (1984) operating systems and applications. Apple mapped the functionalities to key-combinations consisting of the Command key (a special modifier key) held down while typing the letters X (for cut), C (for copy), and V (for paste), choosing a handful of keyboard sequences to control basic editing operations. The keys involved all cluster together at the left end of the...
