About the begin element for animation elements: The value is a (semicolon separated) list, not just one possibility: http://www.w3.org/TR/SVG11/animate.html#TimingAttributes As a device independent event 'activate' is useful, therefore in doubt the author may add it as an additional begin event value to ensure better accessibility. Additionally sometimes the restart attribute may help to avoid some undesired situations with multiple begins (before you are dissappointed, for example Opera ignores 'activate' currently unfortunately. And some more complex situations with restart may be wrong in some viewers too ;o) From Opera I know, accessKey is partly supported. One needs additional keys to activate something, but in SMIL it is noted, that no further key should be required: http://www.w3.org/TR/2001/REC-smil-animation-20010904/#Timing-AccessKeyValueSyntax Therefore usable, but not completely correct, independent from the question, whether it may be a practical problem for general purpose viewers to do this without a further key ;o) I cannot understand, how the lazy interaction sample from SMIL is related to you question. The value of an end attribute can be a list too, this is similar to begin. Additionally there are different possibilities in SMIL animation to have influence on the active duration with different attributes, this can be very complex and several viewers in the past and the present do not interprete all this completely correct - therefore currently I would like to suggest authors to keep the end of active duration simple, but to check and discuss more complex situations independently to improve both the general understanding of authors and implementors and the behaviour of viewers.
