'Your Workday Is Easier Thanks to His Revolutionary Ideas.' Computer Scientist Who Created 'Copy' and 'Paste' Dies

Larry Tesler, the Silicon Valley pioneer who created the now-ubiquitous computer concepts such as "cut," "copy" and "paste," has died. He made using computers easier for generations as a proponent and pioneer of what he called "modeless editing." That meant a user wouldn't have to use a keyboard to switch between modes to write and edit, for example. "The inventor of cut/copy & paste, find & replace, and more was former Xerox researcher Larry Tesler. Your workday is easier thanks to his revolutionary ideas," Xerox said in a tweet Wednesday.
