# On Orgmode Links and LaTeX Footnotes

When you're using hyperlinks in Orgmode and export them to LaTeX/PDF, there aren't any visual clues that those links actually exists. Unless you set colorlinks=true in your hypersetup. But even if you set colorlinks=true there is still a problem. When you print the PDF and keep it in black and white. Filters come to the rescue.

(defvar org-export-latex-add-link-footnotes nil
"If non-nil links will be added as footnotes if exported to latex.")

(string-match "\\\\href{\$$.*\$$}{\$$.*\$$}" text))

What org-export-latex-link-footnote does, is that it extracts the URL of a LaTeX \href and appends it as a \footnote. So the URL isn't lost after the PDF has been printed. The footnote export process is only active if org-export-latex-add-link-footnotes is non-nil. I set this on a per document basis with #+BIND.
