**Never know that simple “doucle-click” ‘activities also has their own patent and inventor. All this time, thought it is just a normal ‘natural’ mouse’s program. And in that patent, nearly half of it explaining what it is “left-click”, “right-click”, and “left click-movable-section”. The “double-click” system sound easy, but it seems that it is very hard to be programmed. Is it the arrangement of the keyboard have their own patent? Who invented the word ‘mouse’? Who invented ‘shift’, ‘tab’, ‘backspace’ keys. Who invented the USB ‘holes’?
