I know I can link communities in other instances by typing, for example, !AskKbin@kbin.social instead of https://lemmy.world/c/AskKbin@kbin.social , and the link will open in the correct instance for anyone, even people not using lemmy.world.

Is there a way to do the same with posts? For example, this post has a URL of https://lemmy.world/post/1421688, but is there a way to format this so it would link to the correct post for someone on any instance, and not just lemmy.world?
