A bit ago I read the Comment Formatting section in the Markdown help and actually used some shorthand links in a comment. At the time I just assumed that these shorthand links would also work when asking or answering a question even though (in hindsight) the title of the section does not imply this.
But now I have tried the shorthand links in a question/answer and they definitely do not work in that context.
I don't understand why this feature would be restricted to comments. Is this intentional? If so, why?
Here is a list of the shorthand links copied from the help section to illustrate which ones do and do not work outside of a comment.
These short hand links do not work:
[meta], [main], , [so], [su], [sf], [metaso], [a51], [se], [chat], [ask], [answer]
[faq#anchor] (i.e. [faq#questions]),
[meta-faq#anchor] (i.e. [meta-faq#questions]
[something.se] (i.e. [ubuntu.se])
