Description

Scroll

the systematic movement of text or images, either up and down, or from side
to side on a computer display screen with the use of the keyboard arrow keys,
or a mouse. In scrolling down, a new line of text appears at the bottom of the
screen as the line at the top disappears. To scroll up and down using a mouse,
the user would place the mouse cursor on the scroll bar (a sliding rectangular
button located on the right of the display), or on a stationary arrow button at
either the top or bottom of the frame. In using the arrow button, the user would
position the cursor on the button, left click, and hold the mouse button down.
The contents of the screen will move up or down accordingly. To scroll using
the sliding button, the user would place the mouse cursor on the button, left
click the mouse, and leave the button pressed while moving the mouse either
up or down. This causes the screen contents to move at the same speed as the
mouse. To scroll using the arrow keys, a user simply presses the key that corresponds
to the desired direction of the screen contents.
