In 2005, Microsoft applied for a patent on the ‘Page Up’ and ‘Page Down’ buttons and on August 19, 2008 the US government granted them the patent.‚ Microsoft, also known as the “Evil Empire”, has a long history of stealing other people’s ideas and trying to patent them, including “double-clicking buttons” and the mouse scroll wheel.‚ The ‘Page up’ and ‘Page down’ buttons have actually been around since 1982 when they appeared on an IBM keyboard.
Screw Microsoft.
