I just hit an incorrect key sequence in emacs 28.2 and, amazingly, I got a selection of emojis to insert in the doc. The problem is that I have no idea what keys I pressed to get this. Does anyone know? I've done lots of searching and only found commands for emacs 29.
This is an out-of-the-box emacs that was installed when I upgraded Ubuntu 20.04 to 22.04:
GNU Emacs 28.2 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo version 1.16.0) of 2022-12-09
If you have any emoji fonts install emacs should be able to display it without anything extra. But if you want to insert emojis maybe look into the package emacs-emojify. I used this guide to set it up in my config.

I am trying to create a markdown document in Emacs *.
It does highlight the syntax etc. and goes into Markdown mode (I am not quite sure if I installed that package or if it is standard issue)..
Problem:
When I try to create a preview (either via C-c C-c p or the GUI), it returns this error code:
markdown failed with exit code 127
Question
What does this error tell me? Is there a way to get a more complete error message?
The docs for markdown-mode suggest that it calls on an external library such as pandoc, which I have installed. According to these SO questions, pandoc can return this error code, but I could not quite establish what it means.
How do I fix this / what documentation should I go to?
I am pretty new to Emacs, so anything will help. Thanks!
*Emacs version 25.3.1 on a Mac (Sierra 10.12.6)
The simplest fix is likely to install the markdown package using your package manager.
I fixed this error for myself with:
$ brew install markdown
(on MacOS Mojave, at the bash command line). Brew installed the "bottle" markdown-1.0.1.mojave.bottle.tar.gz, after which C-c C-c p or M-x markdown-preview worked to export the markdown file and open a browser window showing the exported file.
On an Ubuntu 19 (and now 20.04 and 21.10) system, sudo apt install markdown worked too.
You could do the same thing with a symlink to pandoc's markdown, but a) this just worked, b) there's no fiddling with a potentially messed up manually created symlink, and c) it's tiny (a 36 KByte executable). Pandoc's markdown may support more "modern" markdown, though.
I recently installed Arch, and the version of emacs that it has comes with an aggressive auto-completion feature that doesn't let me create a new file. It is also very annoying. How do I get rid of it?
I have Archlinux too, but it didn't come with emacs. I think that you have installed this module: http://www.emacswiki.org/emacs/AutoComplete
Check it, and if this is the case, uninstall the addition.
After I have updated my Emacs from 24.3 to 24.5 version, my 1.1 version of cedet (highlight, auto completion and summary function) has stopped working for c mode. When I trying to load these semantic mode individually, I got the following messages:
Buffer myfile.cpp was not set up for parsing
I think someone has asked a similar question in the past:
cedet-semantic error "Idle Service Error semantic-idle-summary-idle-function - Arithmetic error" when parsing linux kernel file "jiffies.h"
However, I am not sure which snapshot version he has downloaded & how to install a snapshot CEDET version. Can someone please help me with that?
After struggled for a while, I figured out something trivial but hard to see. Hopefully this answer will help others who has experienced the same problem.
When I started to use emacs version 24.3 I didn't know the Cedet version 2.0 was already a built-in package at that time. I downloaded Cedet 1.1 version from
Cedet SourceForge website.
And configured that according to some tutorial online by loading my downloaded 1.1 cedet.el file.
Surprisingly this Cedet 1.1 package is still compatible with emacs 24.3 version. Unfortunately this is not the case for emacs 24.5 version, the semantic mode encountered some problem with c mode. Therefore the best solution is to switch back to the built-in Cedet 2.0 version.
If you have used the older version of Cedet, it's possible that the old saved .semanticdb files are not compatible with latest Cedet semanticdb. You can do
rm -rf ~/.semanticdb/
So the new version semanticdb can create and use the new version of semanticdb (my friend helped me with that subtle problem so I can get the built-in Cedet 2.0 up and running).
I learned that CEDET comes built in emacs 24.3.1 which I have installed.
Unfortunately, all tutorials online instruct you to install CEDET and provide you with config files that refer and load the installed packages and files.
How is it possible to configure the built in CEDET and use it without any external installation?
I am not sure how to take advantage of the built in version.
It's circa Emacs 23, but Alex Ott's A Gentle Introduction to CEDET still looks relevant to the built-in version? (it covers both versions).
I've got 129 packets from marmalade-repo.org , many of which list Marmalade package entries, in my Wireshark log. I'm not behind a proxy and HTTP_PROXY is unset. And ELPA (at 'http://tromey.com/elpa/') works fine.
But I get:
Failed to download `marmalade' archive
every time.
I'm on Max OS X Mavericks, all-up-to-date, with Aquamacs, and using the package.el (byte-compiled) as described here: http://marmalade-repo.org/ (since I am on < Emacs 24).
M-x version:
GNU Emacs 23.4.1 (x86_64-apple-darwin12.3.0, NS apple-appkit-1187.37) of 2013-06-13 on acs-trailblazer.ist.psu.edu - Aquamacs Distribution 2.5
What are the next troubleshooting steps I should take?
I've taken Aaron Miller's suggestion and fully migrated to the OS X port of Emacs 24.3 .
I do miss being able to use the 'command' key to go to the top of the current file, and the slightly smoother gui of Aquamacs, but it's no doubt a great port. Due to the issue with Marmalade, Emacs 23.4 won't work with some of the packages I now need (unless they were hand-built).
