Scrolling / Magnifying glass
The TrackPoint Support software gives you two additional features which can
be used with the TrackPoint or external pointing device. You can select either
scrolling or magnifying glass as the feature that you want to use. You can
use the TrackPoint both for pointing and the additional feature by using the
center mouse button to switch its function.
The scrolling feature allows the user to scroll documents and windows automatically.
The window that contains the cursor is selected as the target window for scrolling.
When the user moves the selected device, the pointing device motions are translated
to scrolling motions in the target window. Since the TrackPoint is a variable-rate
2D pointing device, the scrolling is also two dimensional and variable-rate.
The TrackPoint or external pointing device will scroll web pages, text documents,
list boxes, etc.
The magnifying glass feature emulates a magnifying glass in software. The
magnifying glass is a window that magnifies the area underneath it. The selected
device controls the location of this virtual magnifying glass. The user can
move the magnifying glass around the whole screen as easily as moving the cursor.
Since the magnifying glass and the cursor are controlled independently, the
user can utilize this tool without interfering with the original mouse operations.
An additional feature of the magnifying glass is that it allows mouse clicks
to"pass through" to the underlying application.
