Quick answer: Mac laptops have no Page Up / Page Down keys. Press Fn + ↑ for Page Up and Fn + ↓ for Page Down. In most browsers you can also press Space to page down and Shift + Space to page up.
The shortcuts
- Fn + ↑ = Page Up
- Fn + ↓ = Page Down
- Space = page down (browsers and many readers)
- Shift + Space = page up
On a full-size Apple keyboard with a number pad, the real Page Up and Page Down keys are there and work directly.
Heads up: in text editors, Fn + ↑/↓ often moves the text cursor by a page rather than just scrolling the view — which can be surprising if you only meant to look further down.
Paging vs. jumping
Page Up and Page Down move the view one screen at a time. That's perfect for reading, but on a really long page you'll be tapping the keys over and over. When you actually want the very top or very bottom, don't page — jump:
| Goal | Shortcut |
|---|---|
| One screen down | Fn + ↓ or Space |
| One screen up | Fn + ↑ or Shift + Space |
| Straight to the bottom | ⌘ + ↓ or End |
| Straight to the top | ⌘ + ↑ or Home |
Tired of mashing Page Down?
Scroll Elevator puts jump-to-top and jump-to-bottom buttons at your cursor whenever you scroll — click to leap there in one move, or hold to cruise smoothly through a long page without tapping anything repeatedly. It works the same in every app.
