Datasheet

Features The keyboard accessibility functions can be deactivated automatically
after a certain time. Set an appropriate time limit measured in seconds with
the slider. The system can additionally provide audible feedback when the
keyboard accessibility functions are activated and deactivated.
Enable Sticky Keys Some keyboard shortcuts require that one key is kept
pressed constantly (this applies to




Alt ,




Ctrl or




Shift ) while the rest of the
shortcut is typed. When “sticky” keys are used, the system regards those
keys as pressed after being hit once. For an audible feedback generated each
time a modifier key (

Ctrl or



Alt ) is pressed, activate ‘Beep when modifier
is pressed’. If ‘Disable if two keys pressed together’ is selected, the keys do
not stick anymore once two keys are pressed simultaneously. The system
then assumes that the keyboard shortcut has been completely entered.
Repeat Keys Activate ‘Repeat Keys’ to make settings with sliders for ‘Delay’
and ‘Speed’. This determines how long a key must be pressed for the auto-
matic keyboard repeat function to be activated and at what speed the char-
acters are then typed.
Test the effect of the settings in the field at the bottom of the dialog window.
Choose parameters that reflect your normal typing habits.
Enable Slow Keys To prevent accidental typing, set a minimum time limit that
a key must be pressed and held before it is recognized as valid input by the
system. Also determine whether audible feedback should be provided for
keypress events, accepted keypresses, and the rejection of a keypress.
Enable Bounce Keys To prevent double typing, set a minimum time limit for ac-
cepting two subsequent keypress events of the same key as the input of two
individual characters. If desired, activate audible feedback upon rejection of
a keypress event.
Toggle Keys It is possible to request audible feedback from the system when a
keycap modifier key is pressed.
Mouse Activates the keyboard mouse — the mouse pointer is controlled with
the arrow keys of the number pad. Use the sliders to set the maximum
speed of the mouse pointer, the acceleration time until the maximum speed
is reached, and the latency between the pressing of a key and the cursor
movement.
