Handling of the mouse pad
The mouse pad detects the position of a finger by capacitance scanning. This
works even with rubber-gloves for single use, but not with usual working
gloves. If you cannot do without working gloves, please help yourself with a
metal tool with a big and flat bottom, covered by a sticking tape to protect the
mouse pad from being scratched. Additionally the electrical capacitance
between this tool and the environment
must be sufficient (big
overall surface). E. g.
the tubes of big felt-tip
pens are suitable (15
mm Ø, 100 mm length).
Mouse key functions
The mouse keys are situated between the mouse pad and the keyboard edge
close to the user. They work just like usual mouse keys.
Mouse pad functions
Sliding of one finger over the pad moves the mouse
pointer over the screen. Please read about additional
functions, which you might initiate by mistake.
1. Tapping on the pad - in general
No powerful knocking necessary. Just lay down your finger(s) gently on the
pad surface, without hurry while double-clicking.
2. Tapping on the pad - with one finger
a) Tapping once
Tapping once on the pad with one finger works like clicking the left mouse
button once: In text documents the text cursor jumps into the line of the
mouse pointer or a drawing is selected.
b) Tapping two or three times
Double tapping with one finger works like double-clicking of the left mouse
button. In text documents ...
•
... the text cursor either jumps to the tab position, which is next to the
mouse pointer (behaviour at the end of a paragraph)
•
... or a new tab is created at the mouse pointer position (behaviour
inside of a text line)
•
... or the tapped word is selected.
Tapping three times selects the whole paragraph around the tapped word.
The fourth tapping cancels all former selections.
