We press Ctrl+C and Ctrl+V hundreds of times a day without thinking. But “cut and paste” once meant scissors and glue — editors literally cut up paper manuscripts and pasted paragraphs into a new order.

From scissors to software

In the 1970s, researchers at Xerox PARC were building the first graphical, mouse-driven computers. Computer scientist Larry Tesler championed “modeless” editing — the idea that you should not have to switch into a special mode to move text. His work helped establish cut, copy and paste as simple commands that work the same way everywhere.

Why Z, X, C and V?

When Apple built the Lisa and then the Macintosh (1983–84), it put these commands next to each other at the bottom-left of the keyboard, where one hand can reach them next to the Command key:

• X looks like a pair of scissors — cut.
• C for copy.
• V sits next to C and looks like an insertion mark (a caret) — paste.
• Z is the first key in the row — the most important safety net, undo.

Windows adopted the same letters with the Ctrl key, and the combination became universal.

Undo: the most forgiving button

Undo existed in some earlier systems, but graphical applications made it mainstream. It changed how people use computers: once mistakes are cheap, people experiment more. Excel keeps up to 100 undo steps — though running a VBA macro clears the undo history, which is why you should always test macros on a copy.
