2.3 Touchpad
Definition
The Touchpad is an input device for cursor control and menu operation (with
mouse operation) in numerous programs. You can move the cursor to any screen
position by touch.
A left button click on sets the mark. The right button assignment varies, depending
on the user program. You can select objects, process menus or trigger functions
with this Touchpad.
Operation
You can use the Touchpad the very same way as a mouse: the mouse pointer on
the screen follows the movement of your finger on the pad.
You can click on icons or text with both mouse buttons. First, move the mouse
pointer onto the icon. Then, select the icon with a left click.
As an alternative, in a fully graphical user interface, for example, the Windows
GUI, you can mark an icon and then move the mouse pointer on top of it. You can
then open the icon with a double tap on the Touchpad.
You do not have to apply any pressure on the pad with your finger. The sensor
does not react to finger pressure, but rather to the brief capacitance change on the
touch point.
The touch pad function (mouse pointer and buttons) can be toggled on and off with
the key combinations Fn + ~.
