Copy-and-paste

In human–computer interaction, cut, copy and paste are related commands that offer a user-interface interprocess communication technique for transferring data. The cut command removes the selected data from its original position, while the copy command creates a duplicate; in both cases the selected data is kept in a temporary storage tool called the clipboard. The data in the clipboard is later inserted in the position where the paste command is issued. The data is available to any application supporting the feature, thus allowing easy data transfer between applications.

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 close associations with related techniques in graphical user interfaces that use pointing devices such as a computer mouse (by drag and drop, for example).

The capability to replicate information with ease, changing it between contexts and applications, involves privacy concerns because of the risks of disclosure when handling sensitive information. Terms like cloning, copy forward, carry forward, or re-use refer to the dissemination of such information through documents, and may be subject to regulation by administrative bodies.

The term "cut and paste" comes from the traditional practice in manuscript-editings whereby people would cut paragraphs from a page with scissors and paste them onto another page. This practice remained standard into the 1980s. Stationery stores formerly sold "editing scissors" with blades long enough to cut an 8½"-wide page. The advent of made the practice easier and more flexible.
