Sometimes I want to link to a comment inside another comment, so I strip away as much cruft as possible. Often the copied link includes noredirect=1 or whatever, and that can go away. I've noticed in fact that the slug can go, too: https://meta.mathoverflow.net/questions/4763/is-linking-to-c‌​omments-possible#com‌​ment24200_4764 can be shortened just to https://meta.mathoverflow.net/questions/4763#comment24200_47‌​64. However, this seems to break when there are multiple pages of answers. In that case, what is the minimum I need to keep to link to the correct comment? — LSpice 1 hour ago

@LSpice You can shorten it further by using /q/ or /a/ instead of /questions/. I guess adding the comment to the link to the answer should be reliable - one would expect that it works when the anchor is actually located on the page. So I would expect this one to work: https://mathoverflow.net/a/2431#comment2259_2431. Test: mathoverflow.net/a/2431#comment2259_2431 And using link to the question would work only if this answer gets to the first page in the ordering you're using: https://mathoverflow.net/q/2340#comment2259_2431.
