The SMIL Animation spec is the place to look for that information (at

That's another separate issue, which has little to do with the standard.  
Opera has a number of one-keystroke shortcuts which may conflict with  
accessKeys at any time, and I believe that was part of the reason there is

SVGT12 references the DOM 3 Events spec, which defines some key  
identifiers. However it's still in working draft status.
