Where Is Page Up and Page Down Keys On The Mac?

If you are using Apple keyboard without the numeric keypad or the keyboard on your MacBook/MacBook Pro, there is no Page Up and Page Down keys.

Instead you use Fn-Up Arrow (Fn key together with Up Arrow) for Page Up, and Fn-Down Arrow for Page Down.

For some app such as Safari and the message view screen in Apple Mail, pressing the Spacebar achieve the equivalent of Page Down and Shift-Spacebar is the Page Up.
