1. Place the cursor over the document or Web page to scroll through.
2. Press and hold down the TrackPoint center button. The scrolling icon will replace the cursor icon on the display to indicate that the TrackPoint scrolling function has been enabled.
3. To scroll through the document or Web page, continue to hold down the TrackPoint center button and push the TrackPoint in the direction to scroll. You can scroll both vertically and horizontally.

Note: The harder the TrackPoint is pushed, the faster the document or Web page will scroll. The TrackPoint scrolling feature can also scroll the document or Web page directly beneath the cursor on the display. This allows documents or Web pages to be scrolled behind the active application window.

1. Place the cursor over the portion of the screen to be magnified.
2. Press and hold down the TrackPoint center button. The magnifying glass window will open and magnify the area beneath the cursor on the display. The magnifying glass icon will also appear on the 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 in the direction to move while continuing to hold down the TrackPoint center button.

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

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 pasting 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.
