Apple started working on how to make computers as easy to use as possible in the 80s and introduced the first Apple Macintosh in 1984. For many years computer experts smiled at the single button mouse Apple invented to navigate through the graphical user interface of the operating system and applications. It was very easy to use for beginners and an important part of the success of Apple in the consumer computer market. But even today many people (including some "experts") don't know the Mac OS was always adapted to interface with the single button design using keystrokes in combination with button clicks to recreate some of the features desired from the original Xerox three-button mouse. For example, the control key is mostly used to simulate the second button and to get context menus. The software developers at Apple always had fun including (mostly undocumented) shortcuts as "hidden features" inside the operating system. To get an idea of it, this manual provides an overview of the most important and helpful shortcuts of the Apple Finder. You can download it as a PDF if you click on the red icon below.
