 Object Events Summary
 
 ■ Events are used with forms and controls to detect and perform actions.
   When a valid event is detected, a special SUB procedure (called an event
   handler or event procedure) is invoked. Visual Basic supports several
   common events, including the detection of keystrokes, button clicks, and
   mouse clicks.
 
 ■ In earlier versions of Microsoft Basic, event statements were used to
   detect events from module-level code. The occurrence of an event caused
   the program to jump (using a GOSUB statement) to a particular line label
   at the module level. This type of event-handling functionality is
   included in Visual Basic for compatibility only. Use object-specific
   events with forms. See: ◄Error/Event Trapping Summary►
 
 ■ Each event applies to a specific set of objects. A list of applicable
   objects is defined in the Help topic for each individual event.
 
 ■ Use the following syntax for form events:
 
         SUB Form_event ()
 
         • event      Name of the event
 
  ■ Use the following syntax for control events:
 
         SUB ctlname_event ([Index AS INTEGER])
 
         • ctlname    Any valid control name
 
         • event      Name of the event
 
         • Index      Identifies which control receives the event in a
                      control array
