Keyboard commands for copying and pasting data were created by computer scientist Larry Tesler in 1973 while working on text editing software at the legendary Xerox PARC research facility.

From Text Commands to a Reusable Clipboard

The important shift was not simply replacing a long instruction with a shorter keystroke. It was treating a piece of text as something a person could temporarily hold, move, and reuse. In the text-editing work Larry Tesler helped develop at Xerox PARC, commands for cutting, copying, and pasting made that idea part of an interactive editing workflow.

A clipboard is a temporary holding place for selected material. Copy puts a duplicate there while leaving the original in place; cut removes the selection and puts it there; paste inserts what is being held at the cursor. Because the same stored text can be inserted somewhere else, the user can rearrange a passage without retyping it or composing a new command for every change.

Why the Pattern Endured

These actions also gave editing a simple, repeatable sequence: select the text, choose what to do with it, then place the cursor where it belongs. The computer handles the transfer between those steps. That separation makes the operation easier to learn and lets the same basic commands work across different documents and, eventually, many kinds of software.

The familiar keyboard shortcuts became a compact way to invoke those editing actions, but the deeper design contribution was the interaction model: text could be handled directly as an object on the screen, rather than only through instructions typed out in a command language. A sentence could be moved with a few deliberate actions—and, if copied, used again without disturbing the original.
