Based on an idea of @dimension10 I have added two buttons below all posts:
- permalink: Copies the shortest possible URL of the post to your clipboard.
- cite: Copies the bibliographic data in BibTeX, as defined here, of the post to your clipboard.
I am not able to test it on all existing browsers and would be thankful if you would report your experience (positive or negative) as comment below this announcement. Please note there also your browsers name and version.
