When I close a question as off-topic, I generally add a link to the What topics can I ask about here? with a quote of the description that applies to the asked question. (For example, "Implementing a functionality, or a layout, seen in a site for which only a screenshot, or the site URL is provided.")
I tried using
[faq#on-topic], but that doesn't point to the right page.
Is there any magic link I could use in comments for the page listing the topics for which questions can be asked? If there isn't any, consider this a feature request.
