# Shortcut link to another Stack Exchange site

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.

• It might also be worth nothing that some sites have redirects. For example, Space Exploration also has the domain name thefinalfrontier.stackexchange.com. – HDE 226868 Mod Oct 30 '15 at 21:25
• last line: magic links (e.g. [so]) only work in comments; answers need full (general) form (e.g. [stackoverflow.se]). – JDługosz Oct 30 '15 at 23:03
