I thought that one thing that would be nice is being able to open pdfs in it from outside Emacs. For example, texdoc could use it instead of Evince (which is pretty nice, but it’s not Emacs!).

• 17:19 UTC (new) (history) 2026-06-22 Disabling minor modes with local variables . . . . mbork – I’ve known about file local variables for a long time. I also knew about the eval keyword, which can be used as a file variable, but instead of binding the given value to the (non-existent) variable eval, Emacs evaluates it. This is often useful, but the usefulness is diminished by the fact that Emacs nags the user whether it is safe to evaluate a form provided that way. (Of course, it is reasonable security-wise, and that’s why I didn’t set enable-local-variables to :all – I still prefer the nagging to the risk of executing untrusted code!) There is, however, one case where the eval form seems safe and useful enough to grant an exception: enabling or disabling minor modes.

It is not ideal, though – or at least, not ideal for me. One feature of Emacs I often use is the scroll-other-window command (bound to C-M-v), and its sibling scroll-other-window-down (C-M-S-v). They are extremely useful for example when reading documentation or watching live Markdown preview, and I wish they worked with the TeX and pdf-tools duo, too. Well, it’s Emacs, so it shouldn’t be difficult to make them!

When I got back, I sat to select some of them to make a gallery for my family and friends. I started with copying all pictures from two mobile phones and a camera to my laptop. Then I wanted to copy a few carefully chosen images to one directory. To my surprise, Emacs’ Image mode does not have a command to copy the currently viewed image to another directory.
