Introducing Your Computer

This is your monitor. No, it does not "monitor" your Web surfing activities. This is your mouse. No, it is not a disease-carrying rodent.
This is your keyboard. No, there is not an "any" key. When a program says Hit any key to continue, it means that you can hit whatever key you want, although it should be a key that transmits a character, not a modifier like SHIFT or CONTROL.
