How do scroll on a MacBook Air to edit the rest of my employees pay? I know this is so simple, it's annoying me as much as this question has annoyed you! lol

Hello Barry12, 

Welcome to the Community page, 

Hope this helps you-

Select "Trackpad" from the "Hardware" section. Click the box next to "Scroll" under the "Two Fingers" heading if the checkbox is not already selected. Close System Preferences. Place two fingers on your Macbook's trackpad and move them up or down to scroll up or down through your current Web page or document.
