Answer 1

Answer:

TO SCROLL DOWN THE SCREEN

Answer 2

Answer:

The scroll wheel that is located in the middle of the mouse is used to scroll up and down on any page without using the vertical scroll bar on the right hand side of a document or webpage.

The scroll wheel can also be used as a third button on the mouse. For example instead of pressing the left button to click on a link in a webpage you can press the scroll wheel just once and the link will appear in a new tab on the web browser. You can also close a tab by clicking on it with the scroll wheel.

You can also press and the scroll wheel down to scroll up and down a document and page at a faster pace than pushing the scroll wheel with your finger.
