At this point I know how to add a clickable link in my answer, and I can create such a link to a question by copying the URL from the top of the browser. But if I want to make reference to someone else's answer, how do I create a clickable link to it?
Each question and answer has a
share link underneath it. If you click on that, a small box with a link will pop up. You can then simply copy that link and paste into your answers.
It's helpful to insert the question itself as the text of the link. You do this in markup in the following way:
[ text here ](link here)
If the link is to a question, then the title of that question will be automatically inserted. So

will display as

There is now a stackapp Greasemonkey script which will give you a
copy button similar to the
link button below posts:
Copy Question Link Markdown - Making it easier to copy links to questions!
It provides you with the
[<title>](<url>) format required. You can use it in comments and also in question or answer posts.
I found a few issues with the script and rewrote parts of it. The revised version can be found as answer to the above stackapps post.
