A Trigger is an advanced Form component that is used to jump to a particular Field in the current Form when the user presses a particular hardware key on the collection device. It can also be used to enact a jump after a specified timeout. Once declared, a Trigger will apply to the entire Form unless it is contained in a Page, in which case it only applies to that Page.
Assume we are creating a Form which has some Field at the end with ID “lastField”:
<Trigger jump="lastField" key="VOLUME_DOWN|VOLUME_UP|VOLUME_MUTE" />
The trigger allows the user to jump straight to the final Field in the Form by pressing any volume button.
