Hi BB,
Not an issue that I've run into with my current MacBook Pro, or with the one before that. Not certain, but I think the current one has not yet had a mouse attached to it.
The trackpad in the space between you and the keyboard of your MacBook Air should provide all the services available from a mouse. See the TrackPad section of System Preferences for instruction on these features and how to use them.
Scrolling up to a previous page can be done with these actions:
- touch one finger to the pad, then slide it toward the right side of the page.
You should see a vertical cursor with splayed ends and a short horizontal line crossing the middle of the vertical line.
When you drag it out of the text area, the cursor should change to an arrow.
- Drag the arrow to the vertical bar at the right of the screen.
- With the point of the arrow on the bar, use your thumb to press near a bottom corner of the pad, and with it pressed, use a finger to drag the bar upward to scroll toward the top of the document.
- When you get to where you want to go, lift your hand to release the pad, and leave the page where you want it.
Regards,
Barry
PS: You can also scroll up and down the document using a two finger sweep to 'pull' the document in the direction you want it to go.
