NEW YORK (AP) — If you have ever used computer shortcuts like “cut,” “copy” and “paste,” you might want to tip your cap to a man named Larry Tesler. The Silicon Valley pioneer who invented the valuable keyboard tools for those who type for work, school or home has died. In 1973, he joined a research center at Xerox and came up with concepts like the series of commands so many of use to process text, numbers and images. He continued that work when he joined Apple in 1980. Larry Tesler was 74.
