Customizing the TrackPoint
– Neither
This function disables the scrolling and magnifying glass
functions.
Choose Scrolling Method
Select one of the following radio buttons:
– Press Center Button, then use TrackPoint
This option enables you to hold down the center click button
on the keyboard and then use the TrackPoint to control the
scrolling or the magnifying glass. When you are not holding
down the center button, the TrackPoint operates normally;
that is, it controls the mouse cursor.
– Use External Mouse
This option sets an externally attached mouse to scroll (or
move the magnifying glass) horizontally or vertically. The
TrackPoint functions simply as a cursor.
– Use TrackPoint
This option sets the TrackPoint to scroll horizontally or
vertically without your holding down the center button. Use
an externally attached mouse as a cursor.
You can still use the TrackPoint to control the mouse cursor
by pressing the center button.
The Use External Mouse and the Use TrackPoint radio buttons
are enabled only if a mouse is attached.
