5.5.6.1 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 keyboard keys, the external trigger (scan button) is software-based.
When the specified key is pressed, the owner (for example, a decoded scanner) is sent
amessage.
Double-Click
When a key is pressed and released, then pressed again within the configured time (between
0 to 1000 milliseconds), a double-click occurs. See also “Trigger-Press Type” on page 114.
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.
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.
