Super Search shows you the parameters for the search you performed so look it up yourself.

No, I don't like that Super Search links to restricted-access nodes as part of documenting what section a node was posted to. But, no, I don't like RAT's interface; "P" and "T" don't mean much to me. "Re" is only present if a node is a reply so it makes sense for "Re" to link to the parent that the node is "Re" to. "^4" is only present if the node is a deep reply and it makes sense for a link to the root to only be present when "^4" is present and a link that goes "up 4 levels" to the root seems reasonable to display as "^4".

RAT's and my choices are both compact interfaces that are easy to remember when you are used to them. Hover text helps in both cases (perhaps the new links won't have hover text with double-escape brackets, though). But I find my choice even easier to remember because what the links go to is actually determined by when the links would be present (as well as being more compact).
