Subject: [PATCH] org.el (org-latex-preview): With an active region, act on it
Date: Wed, 8 Jun 2022 11:35:51 +0000 [thread overview]
Message-ID: <0af38c34-2513-2f17-8b83-4ba3ad5724d7@posteo.eu> (raw)

Hi,
The attached patch modifies org-latex-preview to display all images of
latex fragments in a region, when one is active.
Using prefix arguments it is already possible to display all images in
the buffer, or in the current section, but I find it often too slow and
unnecessary. Regards,
