Defining Desktop triggers

Some triggers correspond directly to an action by the user, such as clicking once on an icon to select it (the select trigger). These triggers are defined in the Desktop ``trigger table'', which is specified by the Desktop trigger mappings resource. Triggers not defined in the trigger table are commonly used for higher-level functions such as requesting help on an icon, or printing.

This chapter describes:

• what triggers are
