Single post in A Somewhat Extensive Guide to BBCodes

I dont know if this counts as Coding but I wondered if someone could help me please? :S How can I link to a specific comment on a forum without the whole Forum coming up? Ive seen people do it before where if you click the link, it only shows that specific message / comment, rather thab the whole Page. For example, Say I have a Journal with all my Info on, But I only wanna Link my Wishlist to my Art Shop, rather than the Entire Journal I could be blind and it might show on the first page, but I cant see anything about it :S Thank yous!
