There is a List of unlinked pages on Stack Exchange sites but it only covers URLs you'd normally don't find. I don't think there's a unified location document for 'public' URLs, so here's an attempt:

Questions

• Canonical form: /questions/[question ID]/[question title]
  • Most links generated by the site itself have this form (e.g. question lists, sidebar widgets)
  • [question title] is not the full title if it's longer than 80 characters
  • What you type as [question title] doesn't matter; if you type something else, it'll still redirect to the canonical form (which exists for SEO purposes)
  • If you use an answer ID instead of a question ID, it'll still work and redirect to the canonical form (of the answer)
  • Parameters (here is an extended list, not sure if it's up to date):
    • lq=1: visited from the Linked Questions sidebar widget
    • rq=1: visited from the Related Questions sidebar widget
    • noredirect=1: prevents redirection to original question (only active for anonymous users)
    • lastactivity: links to the last activity (edited post, new answer) on the page
    • cb=1: visited from the Community Bulletin (sidebar widget with Meta posts and blog links)
    • r=SearchResults: visited from a search results page
• Short form: /q/[question ID] or /q/[question ID]/[user ID]
  • This is the link you get by clicking the share link underneath a question; the user ID is the one currently logged in, not the author. It makes sure the link counts for the Announcer badge and its kin.
  • If you use an answer ID instead of a question ID, it'll still work and redirect to the canonical form (of the answer)
• An obscure form, used in the newsletter: /landing/r/newsletter?cta=question&id=[question ID]

Answers

• Canonical form: /questions/[question ID]/[question title]/[answer ID]#[answer ID]
  • This is basically an extended version of the canonical question URL; again, only the question ID and the last answer ID matter (the latter because it scrolls the page to the right position).
  • The first answer ID matters if there are too many answers to fit on a single page; it makes sure the correct page is displayed.
• Short form: /a/[answer ID] or /a/[answer ID]/[user ID]
  • If you use a question ID instead of an answer ID, it'll still work and redirect to the canonical form (of the question)

Posts / revisions

• Edit post: /posts/[post ID]/edit
• Revision history: /posts/[post ID]/revisions
  • Can be visited via the 'edited x hours ago' link underneath a post, but works when there is only a single revision too.
• Single revision (rendered): /revisions/[post ID]/[revision number]
• Edit post, starting from a particular revision: /posts/[post ID]/edit/[revision GUID]
• Single revision (markdown): /revisions/[revision GUID]/view-source

Comments

• Canonical forms:
  • /questions/[question ID]/[question title]#comment[comment ID]_[question ID]
  • /questions/[question ID]/[question title]/[answer ID]#comment[comment ID]_[answer ID]
  • Most of the remarks about questions and answers applies here, too
• Short form: /posts/comments/[comment ID]
  • This format (with a noredirect parameter) is used in the global inbox.

Users

• Canonical form: /users/[user ID]/[display name]
  • What you type as [display name] doesn't matter; if you type something else, it'll still redirect to the canonical form (which exists for SEO purposes)
  • For your own user (for ♦ moderators, all users), this shows the Activity page; for other users, the Profile page
  • Navigation is possible with
    • the tab parameter (for the top tab: Profile / Activity and the second Activity tab (Summary / Answers / Questions etc.)
    • the sort parameter (for subtabs; sometimes it does affect the sorting, e.g. answers by votes or by creation date; sometimes it's just an additional filter, e.g. with votes)
    • the page parameter
• Shortcut to current user: /users/current
  • Redirects to your own user page
• Short form: /u/[user ID]
  • Even works for deleted users (♦ moderators are able to view them)
  • Doesn't support current
• Edit profile page: /users/edit/[user ID]
  • Normally only works on your own user ID; ♦ moderators can edit other users' profiles as well.
  • You can use current as user ID to create a link to your own edit profile page.
• Flag summary: /users/flag-summary/[user ID]
  • Normally only works on your own user ID; ♦ moderators can view other users' flag summaries as well.
  • You can use current as user ID to create a link to your own flag summary.
