What's the shortcut syntax to link to another Stack Exchange site? I can't remember and it's not in the help center! But I know it's worked before.

The general form is [sitename.se] where sitename is the part of the fully qualified domain name preceding stackexchange.com. For example, [worldbuilding.se] or [biology.se] or [meta.space.se].

Some sites have special "magic links", like [so] (Stack Overflow), [sf] (Server Fault) and so on.

You can also use links like [meta] and [main] to link back and forth between a single site's meta site and main site.

There's more; see Add data.SE style “magic links” to comments for a (hopefully current) list.

Note that these magic links only work in comments. In questions and answers, use the full form.

  • $\begingroup$ It doesn't seem to work for me. I tried Physics in an Answer (full form, not a magic abbreviation) and it doesn't take. I see it working in this comment, though. $\endgroup$

    $\begingroup$ @JDługosz, you should probably re-read the very last line of the answer :) $\endgroup$ Commented Oct 30, 2015 at 22:42
  • $\begingroup$ last line: magic links (e.g. [so]) only work in comments; answers need full (general) form (e.g. [stackoverflow.se]). $\endgroup$
