On WaniKani forum Post Search r###lts, the r###lts link only to the topic, not the individual post.
This script enables you to navigate directly to the individual post.

Instructions:
1) Do a "Chat Posts" search
2) Click on "(get link)" next to the search r###lt that you want to navigate to.
3) The "(get link)" will briefly change to "(one moment...)" while it finds the desired post.
4) The "(one moment...)" will change to "(click to go)" when the post is found.
5) Click ("click to go") to navigate to the post.

I use a two-step process (get link, then click link) to allow you to 'open link in new tab' if you want.
