Gates, Jobs etc were all still in elementary school, when Doug Engelbart invented the mouse. IIRC Woz was first to use it at Apple, on Lisa; and he got the idea when he saw the Xerox Star at Parc Place.
I use Winkey+R for shell:commands, so it always has those I frequently use in its MRU list, so I neither have to type or remember them .
I can't remember in which tin Windows keeps things, such as taskbar and start menu pins. One of them is hidden away in an Internet Exploiter directory
