You've made a similar misunderstanding to a previous message
(my reply to that is [1]).

The "Animation event name" is the name used within event-value
for animation begin and end. For example "circleA.click" corresponds
to the {"http://www.w3.org/2001/xml-events", "click"} event on
the element with id "circleA". You can find this information
described in the animation chapter under "begin" attribute syntax.

Here is the relevant extract:

event-value ::= ( Id-value "." )? ( event-ref ) ( S? ("+"|"-") S?  
Clock-value )?

Describes an event and an optional offset that determine the element  
begin. The animation begin is defined relative to the time that the  
event is raised. The list of event-symbols available for a given  
event-base element is listed in the 'Animation event name' column in  
[Complete list of supported events].

You're correct that not all events can be used as event-refs. In  
particular, events which have parameters, such as which key was  
pressed and how far the pointer/wheel was moved, would require an  
extension to the syntax. This will be considered in future versions  
of SVG.

Please respond within two weeks if you are not satisfied.
