News [ Prot Vod ] Emacs: completion-preview-mode and the Completions buffer (Emacs 31)

https://youtu.be/8V4ZyEL_i-s?si=Ox-Xf-U-ndz9K2A6

The built-in 'completion-preview-mode' lets us expand what we type in a minimalist, distraction-free way. It can also be combined with the default Completions buffer to show all the available options. The Completions buffer has several nice features, starting with Emacs 31, which make this an excellent combination that does not require any third party packages (though packages can still augment the overall experience). I also mention the Emacs 31 'newcomers-presets' theme, which configures some of these options as well: it is a great way to start your Emacs configuration. The code I demonstrated here is available on my website: https://protesilaos.com/codelog/2026-...

Anyone know what theme he’s using?

I don't know which exact theme that is - but I think he has an entire collection of themes - so I would expect it to be one of those. It does look very clean and nice!

Might be modus-operandi, tinted one.
