Intro This wasn’t always the case, but I find that now emacs is ignoring some files when I do find-file. The most annoying example is .git not appearing, although I can navigate through it if I type it fully. This seems to happen whether I am using my vertico for find-file, or if I disable vertico and try using tab-completion in a raw find-files. How can I find out what is being ignored, and change/disable it?

Intro I upgraded orgmode recently and added org-contrib to my loading. I’m not sure if that’s related or not, but suddenly, when I invoke org-capture on a Gnus message (which used to happen seamlessly, suddenly I am getting the following selection message, asking me whether I want org-mairix-store-gnus-link or the old working default org-gnus-store-link . This is the first time I have ever heard of Mairix, and I can’t find any customizations to set to get it to stop asking me.

M-x helm shows duplicates after upgrading to Emacs 27. Turns out the changed behavior is easily fixed by configuring history-delete-duplicates. Answer courtesy official issue .

Version at time of writing: Firefox 79.0 First, locate your profile by going to the firefox menu bar: Help -> “Troubleshooting Information” and find on the page “Profile Directory”. Navigate there, where you’ll be making/adding two files that allow you to customize behavior and appearance of Firefox. For reference, mine was here: ~/.mozilla/firefox/aabkj82t.default/ . Yours will have some other blob of random characters before “.default”. userChrome.css This file should definitely exist already.

I sensed I could improve how my directories appeared in dired, instead of just being bold-face. The question was, how to find which face to change to get the desired result? Digging through my customize-faces options was tedious and sometimes misses the tree for the forest unless you know which one you’re looking for. Locating the face at point Enter the beautiful self-documenting nature of Emacs. Put your cursor on the thing you want to change (remember, our whole philosophy emacs inherited from *Nix is that everything is text).

https://www.reddit.com/r/emacs/comments/fcernd/how_to_find_the_highlight_face_in_emacs/ The doom themes I try all have too un-obvious a background color for selected text – the text of future matches when doing an interactive search, or the highlight color of matches while I’m spell-checking, or the mark area when I am highlighting a section of text. I assume these are all the same face, because they look the same. Does anyone know which face this should be so I can customize it, and secondly, can tell me how I could figure out the answer to this question on my own without reading a lot of code?

I had a problem where my orgmode agenda had stopped displaying my “scheduled” items, which I require for my workflow. I must have been playing around with the customize group when I broke this, because that’s where I found the answer: I had set a non-zero number and needed to reset to 0 here: customize-variable Org Scheduled Delay Days
