Using the TrackPoint center button for scrolling

1. Place the pointer over the document or web page that you want to scroll.

2. Press and hold down the TrackPoint center button. The scrolling icon will replace the pointer icon on your display to indicate that the TrackPoint scrolling function is enabled.

3. To scroll the document or web page, continue to hold down the TrackPoint center button and push the TrackPoint pointing stick in the direction you want to scroll. You can scroll both vertically and horizontally.

Note: The harder you push on the TrackPoint pointing stick, the faster the document or web page will scroll. Also, the TrackPoint scrolling feature will scroll the document or web page directly beneath the pointer on your display. This allows you to scroll documents or web pages behind the active application window.

Using the TrackPoint center button to activate a magnifying glass

1. Place the pointer over the portion of the screen you want to magnify.

2. Press and hold down the TrackPoint center button. The magnifying glass window will open and magnify the area beneath the pointer on your display. The magnifying glass icon will also appear on your display to indicate that the TrackPoint magnifying glass function is enabled.

3. To position the magnifying glass over a different portion of the screen, push the TrackPoint pointing stick in the direction you wish to move while continuing to hold down the TrackPoint center button.

Note: To close the magnifying glass window, press the TrackPoint center button once again. If you do not press the TrackPoint center button again to close the magnifying glass, it will disappear automatically after 15 seconds. With the magnifying glass open, you can keep the contents of the magnifying glass in focus while you move the pointer and activate another application window.

You can quickly change properties of the magnifying glass window by clicking the left or right TrackPoint button while holding down the TrackPoint center button. This will allow you to adjust magnification power as well as adjust the size of the magnifying glass. This menu also allows you to Copy Magnifying Glass to Clipboard. This function will copy the contents of the magnifying glass and allow you to paste them elsewhere. The 1xZoom in combination with the Custom Glass Size is particularly useful for copying small portions of an application window. To modify the size of the Custom Glass, see Adjusting settings for the TrackPoint center button below.
