Configuring Assistive Technology Support - Novell LINUX ENTERPRISE DESKTOP 10 SP1 - GNOME 23-05-2007 Manual

Enable Sticky Keys (Basic Tab)
Some keyboard shortcuts require that one key (a modifier key) is kept pressed constantly (this
applies to Alt, Ctrl, and Shift) while the rest of the shortcut is typed. When sticky keys are used, the
system regards those keys as staying pressed after being pressed once. For an audible feedback
generated each time a modifier key is pressed, activate Beep when the modifier is pressed. If Disable
If Two Keys Pressed Together is selected, the keys do not "stick" anymore when two keys are
pressed simultaneously. The system then assumes that the keyboard shortcut has been completely
entered.
Enable Repeat Keys (Basic Tab)
Activate Repeat Keys to make settings with sliders for Delay and Speed. This determines how long a
key must be pressed for the automatic keyboard repeat function to be activated and at what speed the
characters are then typed.
Test the effect of the settings in the field at the bottom of the dialog. Select parameters that reflect
your normal typing habits.
Enable Slow Keys (Filters Tab)
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 (Filters Tab)
To prevent double typing, set a minimum time limit for accepting 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 (Filters Tab)
You can request audible feedback from the system when a keycap modifier key is pressed.
Mouse Keys Tab
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.
