Having difficulty with your keyboard or mouse?

Changing your computer screen settings

To change the size of your screen on a computer running Windows, go to Start > Settings > Control Panel > Display > Settings. You can then change the size of the desktop area up and down using the sliding bar.

On an Apple Macintosh, you can use the Monitor & Sound Control Panel to change the screen size.    
 

Having difficulty scrolling using the bar on the right?

Try using the arrow keys on the keyboard to scroll up and down the page. You can also use the ‘Page up’ and ‘Page Down’ keys to move a screen’s length at a time.
