8.4 Key Actions
This tab sheet allows you to adjust the behavior of the single keys strokes of your Braille
System in the following three different ways:
Key Lock: Keys, defined as locked, will be ignored when pressed.
Fast Keys: Keys, defined as fast keys, performs their action already when pressed
and not – as usual – when released.
Repeat Keys: Keyes, defined as repeat keys, will repeat their action continually
while be pressed.
8.4.1 Key Lock
Single keys of the Braille System can be locked to prevent unintentional functions by
pressing a key by mistake. This is helpful when starting to learn how to use the Braille
System.
With the checkbox “Use Key Lock“, you can activate this function. The button “Locked
Keys…” will open the dialog “Define locked keys for device”. In the list box “Device” the
connected Braille display is already preselected. In the list box “Available keys” you
choose the keys to be locked. With the “Add” button you move the selected key into the list
box “Locked keys”. The “Remove” button removes the key back to the available keys. By
default, no keys are locked.
8.4.2 Fast Keys
Fast keys, also known as hot keys, refer to keys that implement the function associated
with that key as soon as the key is pressed, instead of when the key is released. If one of
the keys to be used in a key combination is a fast key, the fast key must therefore be
pressed last.
The check box "Use Fast Keys" is used for enabling this function. The button “Fast
Keys…” will open the dialog “Define Fast Keys for device”. In the list box “Device” the
connected Braille display is already preselected. In this dialog you can then select the keys
you want to define as fast keys from the list box "Available keys" and move them by
pressing the “Add” button into the list box “Fast Keys”. By default, [L] and [R] are defined
as fast keys. There are no fast keys available for Braille input.
8.4.3 Repeat Keys
With the settings under "Repeat Keys" you can specify the repeat interval at which a
function initiated by a key is repeated when that key is continually pressed. This feature
makes it easier, for example, while you are trying to navigate through a list, because you
do not need to keep pressing the forward or backward key for each item in the list, but
keep holding down that key until the cursor is at the desired item.
The check box "Use Repeat Keys" is used for enabling this function. The default setting is
that key repeats are disabled. The button “Repeat Keys…” will open the dialog “Settings
for repeat keys”. In the list box “Device” the connected Braille display is already
preselected. In this dialog you can then select the keys you want to define as repeat keys
from the list box "Available keys" and move them by pressing the “Add” button into the list
box “Repeat Keys”. For the Braille Systems, the keys [1], [4], [L], and [R] are implemented
