Emacs

if you don't want to jump right into configuring things from scratch, I would recommend you start with Doom Emacs.

I started with Doom Emacs (which I've heard is great even if you're not an Evil user), but eventually found the abstractions frustrating and wanted to make Emacs truly my own, at which point I started over with a clean slate and now understand the configuration of my system a lot better.

I wish I'd started configuring it from scratch on my own sooner, for sure, but I don't know that you need to do so from the outset. If you just want to get work done while slowly getting used to the Emacs workflows, a configuration system like Doom's can make that easier. It can also welcome you into Emacs without scaring you away.

That said, the abstractions hide a lot of details of how Emacs works, so if you're sure you're in it for the long term and can take the time now—which is maybe what you mean by "studying Emacs"... it is a thing to study!—then by all means, start from scratch.

Either way, I'll echo u/nv-elisp above—when you're trying to configure something, look at the documentation and articles online before you ask questions! You'll learn how to learn, which will help you immensely with all future problems.

I'd also recommend a couple of packages to make things easier:

• The Helpful package makes the vital and helpful describe commands even more... helpful.
• The Vertico/Marginalia/Corfu/Embark/Orderless/Counsel set of packages greatly improve your ability to navigate around Emacs.

Good luck, and happy hacking!
