Multi-cursor code editing: An animated introduction
You'll need to install an extension for it, but yes it does. Here is one example: https://github.com/magnars/multiple-cursors.el

IRS will officially launch free online tax filing service for 2024 tax season
For me, the beauty of Beancount[0] is that it's just text files in Git. There's a web UI I use for generating reports, and a Python API with which I hacked together some import/export scripts, but 99% of my interactions with it are via Emacs[1] and Magit.
A ton of repetitive bookkeeping tasks become so much easier when you can copy and paste, or use keyboard macros or something like multiple-cursors[2], rather than have to click tens or hundreds of times in a GUI. Many years ago I used QuickBooks, and basic tasks like importing a bank statement took at least an order of magnitude longer than they do now.
Having my company's books in Git is also huge when it comes to auditing, concurrency, backups, and figuring out where things went wrong when accounts don't balance. As mentioned in another comment: `git diff` is a really powerful tool and it's awesome to be able to check out the books as they existed at a particular point in time. `git blame` is great for when things don't balance. Writing meaningful commit messages and comments keeps me sane when I try to remember a year later why something is recorded the way it is.
The biggest downside—or advantage, depending on how you look at it—is that there's no default or built-in chart of accounts, so you need a certain level of accounting acumen (or professional advice) to set things up at first. I'm pretty sure GnuCash aims to be more plug-and-play, whereas Beancount is more akin to a programming library that you use to build an accounting system that works for you. I agree with the grandparent commenter, who said that text-based accounting is "the best and most flexible accounting experience I've ever had." But the cost of that flexibility is that a certain level of base knowledge is a prerequisite.

packages/features/settings that slow Emacs down
The original multiple cursors package is amazing for what it is, but it scales very badly. Emacs is efficient when editing at one place at a time (as you'd do normally), and when mc replicates all the edits character-by-character for all the cursors, it does the very opposite of this: many edits all in very different places. It works quite well when using just a few cursors, but going above a dozen of them causes them to be visibly sluggish.

Multiple-cursors error on Emacs 29.0.60
Recently multiple-cursors has been unusable for me on Emacs 29.0.60 (not a release yet). Movements (and possibly other operations) don't work with the following error:

Best way to "process" a large-ish text file?
If you intend to use Emacs for this (as opposed to some external script), you're probably better off using the keyboard macros or a regular search&replace instead of multiple cursors (I assume the Magnars flavor of them). As flexible as they are, they don't scale well and they get exponentially slower the more cursors you have. Having 2500 cursors sounds insane.

How to do this Vim Trick in Emacs?
You can do something similar with multiple cursors.

If you have never used wgrep with rg.el to rename a function in several files, try it | that will blow your mind
Then, in *rg* buffer, we transform org-link-expand-abbrev into org-link-RENAMED the way we prefer (we have all the Emacs power, some of us might use query-replace, other might use multiple-cursors.el, other iedit, etc.). And so *rg* buffer looks like this:

[Question] multiple cursor and end of line
There is also multiple-cursors.el, which looks the closest to what you want, but it's also the buggiest.

Modeless Vim
You can also use Hydra for Emacs.[1] Once I discovered how to configure Hydra, I made it a habit to make one for every new major mode I need to use.

Can you explain the power of emacs please?
An Emacs specific example: I'm working on a few go projects at the moment and go requires recompilation after changes. Step one was finding auto-recompilers for my projects (I'm using both air and reflex in various projects). Step two was realizing that I spent a lot of time switching to the buffer where the output is printed, so I wrote a little hydra menu to make that easier. Then I found myself having to restart those processes each time I restarted Emacs, so I went digging and found detached to manage the processes. Then I got tired of having to hunt for where the detached output was displayed in my frame so dug into sidebars to manage the windows more effectively.

Is it possible to make god-mode turn off automatically after a command?
I think the goal of the hydra package is to provide such functionality.

Non-evil users: what modifiers do you use on emacs?
I would I also encourage anyone who does not want to use modal editing to look into repeat-mode, hydras, and key-chord.

Newbie question: What is a good strategy for personal keybindings to avoid conflicts, including with packages installed later on?
The C-c prefix is designed for you, the user, to use for your nefarious deeds. Some things that may help with both binding and knowing what key does what would be a menu such as hydras or transient menus (which apparently are part of Emacs now so that's new).

Too many keybindings
For the very same reason, I started to use hydras: https://github.com/abo-abo/hydra - see my config at https://github.com/novoid/dot-emacs/blob/master/config.org

How usable is Emacs with its default keybindings?
Hydra lets you define mini-modes with limited scope.
