Translation Table Syntax
This appendix explains some of the more complex aspects of translation table syntax. It probably gives more detail than the average user will need, but we’ve included it to help clarify this rather complicated topic.
Event Types and Modifiers
The syntax of the translation table is sufficiently general to encompass a wide variety of events and circumstances. Event translations can be specified to handle characteristic user interface idioms like double clicking, dragging, or combining keyboard modifiers with pointer button input. To specify translations that use these features, it is necessary to learn more about the detailed syntax used to specify translations.
An activity susceptible to translation is a sequence of events and modifiers (that perform an action). Events are specified in angle brackets and modifiers precede the event they modify. The legal events that can be specified in a translation are as shown in Table H-1.
