The official documentation for link_to_remote explains this probably
better than I could myself:
http://www.railsbrain.com/api/rails-2.3.2/doc/index.html?a=M002467&name=link_to_remote

Basically though, :update is the id of the DOM element to be updated
(

…content…
. URL in this case is the
“show_body” action of the current controller with the id of the current
comment.
