Larry Tesler, an icon of early computing, has died at the age of 74.

Mr Tesler started working in Silicon Valley in the early 1960s, at a time when computers were inaccessible to the vast majority of people.

It was thanks to his innovations - which included the "cut", "copy" and "paste" commands - that the personal computer became simple to learn and use.

Xerox, where Mr Tesler spent part of his career, paid tribute to him.

"The inventor of cut/copy & paste, find & replace, and more, was former Xerox researcher Larry Tesler," the company tweeted. "Your workday is easier thanks to his revolutionary ideas."
