Variable: org-highlight-links

org-highlight-links is a customizable variable defined in org.el.gz.

Value

(bracket angle plain radio tag date footnote)

Documentation

Types of links that should be highlighted in Org files.

This is a list of symbols, each one of them leading to the highlighting of a certain link type.

You can still open links that are not highlighted.

In principle, it does not hurt to turn on highlighting for all link types. There may be a small gain when turning off unused link types. The types are:

bracket The recommended [[link][description]] or [[link]] links with hiding.
angle Links in angular brackets that may contain whitespace like
          <bbdb:Carsten Dominik>.
plain Plain links in normal text, no whitespace, like https://gnu.org.
radio Text that is matched by a radio target, see manual for details.
tag Tag settings in a headline (link to tag search).
date Time stamps (link to calendar).
footnote Footnote labels.

If you set this variable during an Emacs session, use org-mode-restart in the Org buffer so that the change takes effect.
