Right. See https://www.gnu.org/software/auctex/manual/auctex/Customizing.html . > But based on my later tries, it seems that there is no need to run the > above command at all, and auctex already can give wonderful and rather > extensive completion results with its initial configuration. As described in the above documentation, AUCTeX has built-in support for many major packages. But it doesn't offer support for *ALL* LaTeX packages. Running `TeX-auto-generate-global' analyses all packages installed on your TEXMFSYS tree at that time and generates support files which give completions etc. So you can obtain completions for packages which AUCTeX doesn't support by default. But beware that `TeX-auto-generate-global' is not so smart so that it sometimes introduces unexpected side effects.[1] Regards, Ikumi Keita [1] https://lists.gnu.org/r/auctex/2021-01/msg00037.html
