Emacs is a versatile and highly customizable text editor that has been a favorite among programmers and writers for decades. With its extensive collection of commands and shortcuts, Emacs provides an efficient and powerful editing experience. This blog post will explore some essential Emacs commands and shortcuts that can significantly enhance your productivity. From basic navigation to advanced features, we will cover a range of commands to help you master Emacs and streamline your workflow.


For detailed instructions on installing Emacs, please refer to the official Emacs website. However, if you're a Windows user, I'll provide you with a few commands to help you install Emacs.


To install Chocolatey and use it to install Emacs, follow these steps:

  1. Search for PowerShell and run it as an administrator on Windows.

  2. Go to the Chocolatey installation page.

  3. If this is your first time installing Chocolatey on your operating system, execute the following command in your terminal, based on the instructions provided on the installation page:

  • If the output is "Restricted", enter one of the commands below:
Set-ExecutionPolicy AllSigned


Set-ExecutionPolicy Bypass -Scope Process
  • Regardless of whether "Restricted" was the previous output or not, run the following command (copy and paste it into your terminal):
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString(''))
  • If there are no errors, check if Chocolatey was successfully installed by running the following command:

If the output displays the version of Chocolatey you are using, it means the installation was successful.

  • Now, search for the package you need (in this case, Emacs) by visiting the package search page. Once you find the Emacs package, execute the following command:
choco install emacs
  • Open any terminal of your choice and type emacs to start using Emacs:

Opening files and directories in Emacs is a straightforward process. To open a specific file, you can use the following command:

emacs <filename>

For example, if you want to open the file named "," you would use the command:


On the other hand, if you wish to open a directory, use the following command:

emacs <directory>

For instance, let's say you have a directory called "myProject," and you want to open it in Emacs. You would execute the command:

emacs myProject

By following these steps, you will be able to install Emacs on your Windows system and begin using it for your text editing needs.

Getting Started with Emacs

To open Emacs in the terminal, use the emacs -Q -nw command, and then use Ctrl + x Ctrl + f to open a file by typing the file name at the bottom of the terminal.
