Learn one of the most powerful and customizable tools ever created for programmers, writers, researchers, and power users. This course takes you from absolute beginner to confident Emacs user while also exploring why Emacs has earned a legendary status in computing culture.
Emacs is an extensible, customizable, self-documenting text editor. Originally designed as an editor, it evolved into a computing environment capable of email, programming, note-taking, project management, terminal emulation, web browsing, and much more.
Emacs originated in the 1970s. Richard Stallman played a major role in its development, eventually creating GNU Emacs as part of the GNU Project.
| Year | Milestone |
|---|---|
| 1976 | Early Emacs concepts emerge. |
| 1984 | GNU Emacs development begins. |
| 1990s | Expansion through packages and modes. |
| Today | Modern ecosystem with LSP, Git, Org Mode, and more. |
You can adapt Emacs to fit your workflow instead of adapting yourself to the software.
Editing, Git, terminals, notes, tasks, and programming tools coexist seamlessly.
Skills learned in Emacs remain valuable for decades.

C-h tEmacs uses keyboard shortcuts extensively. The notation may look strange at first.
| Notation | Meaning |
|---|---|
| C-x | Hold Ctrl and press X. |
| M-x | Meta (usually Alt) plus X. |
| C-g | Cancel current command. |
| Action | Shortcut |
|---|---|
| Mark region | C-SPC |
| Cut | C-w |
| Copy | M-w |
| Paste | C-y |
Instead of tabs, Emacs uses buffers. A buffer is an in-memory workspace representing a file, terminal, help screen, or other content.
Emacs can be extended through packages.
