I recently discovered you could link to tags like this. Is there a similarly simple way I can link to questions? If not, maybe adding this could be cool? For example
[q:19] could turn into a link like this:
For questions and answers you may post just the URL and it will be replaced as a link with the question name.
It's more useful than your request because you seldom know the question ID, but it's easy to copy and paste a full link to a question.
(This does not work in comments, but comments do have a set of magic links that are converted into real links.)
