Trigger Mappings

A trigger mapping is an association between a particular key on the keyboard and a driver or application,
the module(s) – sometimes referred to as "trigger consumer(s)" – of the trigger source. Along with key-
board keys, trigger sources can also be grip triggers, external hardware triggers or software-based. When
the specified key is pressed, the trigger consumer (for example, a decoded scanner) is sent a message.
Important: It is not possible to have two or more identical mappings — for example [F1] cannot be
mapped to the Non-Decoded Scanner twice — even if the trigger type is different.
A keyboard key that is used as a trigger source will no longer generate key data or
perform its normal function. For example, if the space button is used as a trigger
source, it will not be able to send space characters to applications.
Double-Click
When a key is pressed and released, then pressed again within the configured time (between 0 to 1000 mil-
liseconds), a double-click occurs. See also "Trigger Press Type" on page 158.
Show All Modules
By default, the trigger mapping list only shows active mappings. Mappings for drivers or applications that
are not currently active are not normally displayed. By checking this checkbox, all mappings, both active
and inactive, are displayed.
Add
Tapping this button brings up the Add mapping dialog (see below), so that you can add new trigger map-
pings.
Edit
Tapping this button brings up the Edit mapping dialog, so that you can edit existing trigger mappings.
Remove
Tapping this button removes an existing mapping.
OK
The OK button in the Manage Triggers screen saves all changes made. If the [ESC] key is pressed, all
changes are discarded.
