Ask yourself how many times you typed the following in a comment:

[meta](https://meta.stackexchange.com)

Me, personally, I'm sick of it. Can we have some data.stackexchange.com-style "magic links" in comments? (inn~iff)

    Requiring a colon in the syntax is less likely to have false positives. Instead of Stack Overflow and [x.se], use [site:XXX] where XXX is SO, SU, SF, or the subdomain of SE. [faq:all] and [faq:section] work, but that leaves nothing for edit except [edit:], which I dislike. Maybe [link:] instead of [site:], then you can include "faq", "meta", and "edit" in [link:].

Most of these now work. My comment below has the following markdown source:

On [main], you are expected to write proper English (as advertised on [english.se]), but here on [meta.se] it's more important to have freehand circles, so please [edit] your post, otherwise I'll have to flag you (see the [FAQ#flagging]). If you're unsure how to use your keyboard, [su] is the right place to ask. There's no Q&A site about unicorns yet, but you can suggest one on [area51.se].

Magic Links

  • Characters within the magic links can be any mix of upper and lower case. Some, but not all, of the magic links will respect the case used in the magic link and use the same case for the link text. This is noted in the entry for those which respect case.

  • On localized sites, the link text for each of the below magic links is localized.

Supported magic links in comments

  • [meta] – links to the current site's Meta; link text is the site name (e.g. "Meta Super User"). Does nothing if the site doesn't have (or already is) a Meta site.

  • [main] – like [meta], just the other way around (i.e. it doesn't work on main sites; only works on meta sites which have an associated main site).

  • [edit] – links to the edit page for the post the comment is on, i.e. /posts/{id}/edit. Link text is "edit" (capitalization is respected).

  • Help center links. Link text for all of these is "help center":

    • [help] – links to the help center (/help).
    • [meta-help] – links to "What is meta?" (/help/whats-meta)
    • [help/on-topic] – links to "What topics can I ask about here?" (/help/on-topic).
    • [help/dont-ask] – links to "What types of questions should I avoid asking?" (/help/dont-ask).
    • [help/behavior] – links to "What kind of behavior is expected of users?" (/help/behavior).

  • [tour] or [about] – links to (<main site>/tour). Link text is "tour" (capitalization is respected). Legacy magic link [about] is still supported.

  • [meta-tour] or [meta-about] – links to (<meta site>/tour). These only work on meta sites. Link text is "tour" (capitalization is respected). Legacy magic link [meta-about] is still supported.

  • [ask] – links to the "How to Ask" page. Link text is "How to Ask".

  • [what you are asking] – links to the "How to Ask" page. Link text is "what you are asking".

  • [answer] – links to the "How to Answer" page. Link text is "How to Answer".

  • Links to the front page of Stack Exchange sites (link text is the site name):

  • [chat] – links to the current site's chat site (https://chat.stackoverflow.com/ for SO, https://chat.meta.stackexchange.com/ for Meta SE, https://chat.stackexchange.com/ everywhere else – that last one showing a list of active rooms from the referring site), the link text being "{site name} Chat".

  • [code block] – links to the "Code and Preformatted Text" section of the Markdown Editing Help page (/editing-help#code). Link text is "code block".

  • On Stack Overflow only:

  • On Stack Overflow and localized Stack Overflow sites (these do not work on the associated meta sites):

    • [mcve], [reprex], [repro], [mre] and [example] – links to the How to create a Minimal, Reproducible Example page for the site. Link text is "minimal reproducible example", or localized text on localized sites. Capitalization doesn't matter and is not respected.

  • Links to specific tags. These work in questions, answers, comments, and chat – but in comments, they are just formatted like regular links, rather than appearing like tags. Link text is just the name of the tag. These will link to the specified tag, regardless of whether the tag actually exists:

    • [tag:tag-name] creates a link to the named tag on the main site, e.g . (Whether it's used on the main site or the meta site, the link will point to a tag on the main site.)
    • [meta-tag:meta-tag-name] creates a link to a tag on meta, e.g . (Whether it's used on the main site or the meta site, the link will point to a tag on the meta site.)
    • (On Meta Stack Exchange, which doesn't have a main site, [tag:tag-name] and [meta-tag:tag-name] work exactly the same way.)

Supported magic links in chat

In chat, only a limited subset of the magic links listed for comments work, plus one chat-specific magic link.

Chat supports the following magic links: [meta], [main], [ask], [answer], all the links to specific sites, and tag links (with tag formatting). Chat also adds [chat-faq], which results in a link to /faq on the current chat database, with the link text "chat faq" (e.g. "chat faq").

The tag magic links work as expected on Stack Overflow Chat and Meta Stack Exchange Chat. However, on Stack Exchange Chat, the chat room in which you use the magic link must be associated with a specific Stack Exchange site, and will take on the formatting of tags on that site. When the room is not associated with a specific Stack Exchange site, the text used for the tag magic link receives no special processing.

Supported magic links in questions and answers

On main sites, only the [tag:tag-name] and [meta-tag:meta-tag-name] magic links are supported in questions and answers. The [meta-tag:meta-tag-name] magic links will be rendered when the post is saved, but do not display as a tag in the post preview while editing.

On meta sites, only the [tag:tag-name] and [meta-tag:meta-tag-name] magic links are supported in questions and answers.

All of the other magic links are not supported in questions and answers.

    @fretje: Nope, we're not doing that. It'll take longer to copy the id out of the URL into your [main#...] markup than just copying the whole link.

    Oops... not as I had in mind... Ok, but I understand adding "/q/6254529" to the url would be easy, but then the problem would be what to put as the link text?

Edit

Some more ideas, since this seems to be still active.

Maybe it could also be useful to add things like:

  • [dupe:92060] for "possible duplicate of "
  • [inbox]
  • [review], but I think this is marginal
  • [privilege:name] to link to a specific privilege description

History

I think this idea can be improved in a generic way like:

[SITE:type:id#anchor]

Where

  • SITE is SF, SO, SU, meta, metaSU with default to the current site
  • type can be user, post, faq with default to post
  • anchor/id can be the id of a post, of an user and anchor a HTML anchor like in the FAQ, or a comment, or a anwser.

You can only use default values from the left. If you specify SITE you have to specify all.

So on this post:

  • [92060] would link to [meta:post:92060]
  • [92060#answer-92061] would link to my answer (need way to identify the answer's numbers)
  • [SU:post:286219] would link to Unix : List children processes for a given pid
  • [user:1228] will link to the user with ID equal to 1228 on meta
  • [SO:user:1228] will link to the user with ID equal to 1228 on Stack Overflow
  • [SO:faq:#bounty] on the "bounty" section of the SO's FAQ

This would save a lot of keystrokes:

[mcve] = [How to create a Minimal, Complete, and Verifiable example](https://stackoverflow.com/help/mcve)

It would mostly be used on Stack Overflow, as I don't think many users of English Language & Usage would find much use for this, but it would be useful for any programming-related Stack Exchange site.

External manuals

Some sites need to systematically reference and link to external documentation and people may be reasonably worried to follow non-standards links.

For example, in the "mathematica.stackexchange.com" site, links to the Wolfram Mathematica functions documentation are often needed, the users need to do

['InputForm'](http://reference.wolfram.com/language/ref/menuitem/InputForm.html)

were the only variable part is the function name.

This could be easily replaced by [rw:InputForm]

Similarly, in "rpg.stackexchange.com" they often link to

[Find Familiar](https://www.dndbeyond.com/spells/find-familiar)

which also has only one variable region on the link and could be easily a magic link like [spell:find-familiar]

Questions and answers

Also, as suggested by @Moog, Magic links to questions are often needed. I would favour the syntax

[q:11350] to be a shortcut to ['InputForm'](https://mathematica.stackexchange.com/questions/11350/xkcd-style-plotsl)

or [q:92060] a link to this question.
