History Plugin: Don't understand all event descriptions

Question

Nearly all event descriptions are clear, e.g. q_post is question posted, however the following 3 are not clear:

in_a_question -> seems to me to have received an answer

in_c_question -> comment ... ?

in_c_answer -> comment ... ?

I guess in - incoming _to_ a - answer or c - comment and the last piece is what item.

Is that correct?

Answer 1

easier than expected when understanding the "syntax":

in_a_question -> received answer on question

in_c_question -> received comment on question

in_c_answer -> received comment on answer
