[Emacs] Getting Started

1. Download and install

Http://www.gnu.org/software/emacs/

Connection: http://mirrors.ustc.edu.cn/gnu/emacs/

After the download is complete, directly decompress the package and run addpm.exeunder the bindirectory. After the download is complete, run the runemacs.exe Startup File.

Ii. Basic operations

At the beginning, I learned how to use Emacs. Based on my learning experience, I recommend that you read the learn-by-doing document first. This document basically covers the basic operations for using Emacs. How can I open this document? You can use the shortcut key c-h t to directly go to this document, or you can find the link to Emacs tutorial in the default display page of Emacs startup, and click "read.

Some basic operations in the learn-by-doing document are listed below:

C = Ctrl, M = meta = alt | ESC, del = backspace

For example, C-F means to press Ctrl and then F. C-h f means to press Ctrl and then h. After C-h f is released, press F.

C-V	Move one screen forward	C-x C-F	Open/create a file in the buffer
M-V	Move one screen down	C-x C-S	Save the Current Buffer File
C-l	Repaint the screen and place the cursor in the middle of the screen. repeating this command consecutively indicates switching back and forth between the center, the top, and the bottom.	C-x C-W	Save the Current Buffer file
C-P	Move to the previous line	C-x C-V	Close the current buffer and open a new file
C-n	Move to the next row	C-x I	Insert a file at the current cursor
C-B	Move one character to the left	C-x B	New/switch Current Buffer

C-d	Delete a character after the cursor	M-x <command>	Execute Command
M-(<del >|< backspace>)	Remove a word before the cursor (the difference between removing and deleting is that the removed content can be recalled, but not deleted)	C-S	Search forward in Current Buffer
M-d	Remove a word after the cursor	C-r	Search within the current buffer zone
C-k	Remove the character from the cursor to the end of the line	C-G	In search mode, return to the position before the start

C-@ | C-spec	Set start ID	C-x 3	Vertically split the buffer into two windows: left and right.
C-W	Remove content from the ID area	C-x O (letter)	Switch to another window
M-W	Copy the content of the ID area	C-x 0 (number)	Close the current cursor window

C-X c-t	Switch the location of two rows	C-x +	Balance the size of all windows

 

3. Help Menu

In addition to the above basic operations, the Help menu is also very important for beginners. Through this help menu, we can find the information we need more conveniently and quickly.

Go to the Help menu and choose C -?

After the preceding operations are entered, emacs will list all the help operations in a new buffer: (common operations are marked in red)

Iv. Experience Sharing

The blogger has just started to use Emacs. It takes more than three months to use Emacs. He has been studying for more than two months and has been away from new users for a month. There is nothing to share here, that is, the most important thing in practice. The best way to learn a tool is to use it. One of the advantages of using Emacs is that the number of times the keyboard is removed by the hand is significantly reduced, and the efficiency is naturally improved.
