Are there other undocumented paths apart from timeline and reputation audit? [duplicate]

Question

I'm aware of these interesting (relative) paths that can be used on any SE site:

• The timeline of a post, such as this example. It has a relative path like /posts/postid/timeline (similar to the path of the revision history of a post, in which the revisions-part of it is changed to timeline).
• The reputation audit on a site, such as this example. It has a relative path like /reputation.

To my knowledge:

• nowhere in the help pages these relative paths are documented.
• there is not even 1 page on any SE site that have a link to any of these relative paths.

I only discovered these (what I call) undocumented relative paths by accident, after I saw them mentioned in some post.

Question: are there any other undocumented relative paths, and available to anybody (so not just mods or so)? If so which ones, and what is their purpose?
