The clipboard was used to transfer all kinds of info between programs on the Mac. One of the revolutionary features that came with the Mac in 1984 was the unique ability to select text or pictures, etc., then copy that data into a clipboard, in order to hold that content temporarily, and then paste it in the same application or in a different one. CopyPaste magnifies and multiplies the usefulness of the humble clipboard. What has made it so widely appreciated? Usefulness. CopyPaste has been massively popular since its first release.
CopyPaste is the original multiple clipboard utility for the Mac.
