How to scroll using a keyboard
Scrolling up and down depends on what you are viewing on the screen. Below is a list of the methods you can use scroll with a keyboard.
Page up and page down keys
The page up and page down keys are the most common method of scrolling one page at a time on the screen. Pressing page up scrolls up one page or gets you to the top of the page. Pressing page down scrolls down one page at a time or gets you to the bottom of the page.
Some people may also refer to the page up and page down keys as the scroll keys, not to be confused with the scroll lock key.
Using the up and down arrow keys scrolls up and down one line at a time. If the page being viewed can scroll horizontally, pressing the left or right arrow keys scrolls the page in the direction pressed.
The spacebar can also be used to scroll down one page at a time when reading a web page. Also, pressing and holding down the Shift and pressing spacebar at the same time scrolls up one page at a time.
How to scroll using a touchpad
Today, most laptops and Chromebooks support the ability to use two fingers on the touchpad at the same time to scroll up and down. For example, dragging your index finger and middle finger down scrolls down on a page. Sliding up with two fingers scrolls up on a page.
The direction the page scrolls can also be adjusted through the touchpad settings.
Edge of touchpad
Some touchpads, especially earlier touchpads without multi-finger support, have scrolling on the edge of the touchpad. For example, dragging one finger up or down on the far right edge of the touchpad scrolls the page up and down. Also, touchpads that support this type of scrolling can horizontal scroll if one finger is dragged left or right on the bottom edge of the touchpad.
How to scroll using a touch screen
