page Turn command :

c-v: Move one screen forward

m-v: Move backward one screen

c-l: Redraw the screen and place the line of the cursor in the center of the screen

Cursor Control :

c-n: Move to Next line (next)

c-p: Move to the previous line (previous)

c-f: Move one character to the right (forward)

c-b: Move one character to the left (backward)

m-f: Move right one word "to Chinese is move to next punctuation"

m-b: Move one word to the left "to Chinese is to move to the previous punctuation mark"

c-e: Move to end of line

m-a: Moving to the beginning of a sentence

m-e: Moving to the end of a sentence

m-<: Move to the beginning of all text

m->: Move to the very end of all text

On most keyboards, the greater than and less than sign need to be entered with Shift.

Numeric Parameters :

c-u n cmd: command cmd executes n times repeatedly.

For example: C-u 8 c-f will move forward 8 characters.

Terminate command :

c-g: You can terminate a command that has been executed too long, or you can cancel the numeric parameter and enter only half of the commands.

Turn off the other panes :

c-x 1: Turn off all other panes

There are a series of commands that start with c-x, many of which are related to panes, files, buffers, and so on.

Insert and delete :

<Delback>: Delete a character before the cursor

c-d: Delete a character after the cursor

m-<delback>: Remove a word before the cursor

m-d: Remove a word from the cursor

c-k: Removes the character from the cursor to the end of the line

m-k: Removes the character from the cursor to the end of the sentence

In the Windows keyboard, the Backspace key is <Delback>.

to remove any part of the buffer :

First move the cursor to the end of the area you want to remove, press [email protected], then move the cursor to the other end, press c-w to remove the text between two points

recall the removed text :

c-y: Inserts the last removed content at the cursor

Continuously press c-y, you can recall the last removed text, which actually realizes the function of copying.

m-y: Inserts the previous removed content at the cursor

Press M-y continuously to recall content that was removed the previous time.

Revocation :

c-x u: Eliminate all changes caused by one command

file :

c-x c-f: Looking for a file

c-x c-s: Save this file

If a file is found that does not exist, a new file is created. However, Emacs does not actually create the file until you save it.

You can use C-x c-f to open multiple files, to cut back the first file, you can also use C-x c-f.

buffers :

Emacs places the files in each edit in a place called buffer. In each search for a file, Emacs creates a buffer within it.

c-x c-b: List all current buffers

c-x b: Toggle Buffer

c-x s: Saving multiple buffers

Buffers and files are corresponding, so you can also switch buffers with c-x c-f.

However, the buffer does not always have a corresponding file: For example, "*messages*" buffer has no corresponding file, it is stored in the bottom of the EMACS message.

command Set Extensions :

C-x: Character extension (after c-x, enter another character or key combination)

M-x: Command name extension (after m-x, enter a command name)

C-x has a lot of extension commands, the above has learned C-x C-f, c-x c-s and so on. Another example:

c-x c-c: Leaving Emacs

Command name extensions such as:

m-x replace-string: Replace one string with another within the full text range

Auto Save :

Emacs periodically writes the file being edited to a "AutoSave" file with a "#" character in the original file name. The file will be deleted after the normal disk is saved.

m-x recover file<return>: Recovering files

Toggle Main Mode :

m-x text mode<return>: Switch to Text mode (can also switch to other modes such as fundamental, etc.)

c-h m: View the document for the current main mode

Secondary mode :

Auxiliary mode provides some auxiliary functions. Each auxiliary mode can be turned on and off independently, regardless of the other auxiliary modes, and not with the main mode. Such as:

m-x Auto Fill mode<return>: Start/close auto wrap mode

c-u c-x F: Set the maximum number of characters per line to 80

m-q: Manual Wrapping (the cursor must be in the segment where the line is to be broken)

Search :

c-s: Search Down

c-r: Search up

Emacs is a progressive (incremental) search, meaning that the search and input are simultaneous.

Press C-s once again to search for the next occurrence. Press <Return> to end the search.

multiple panes :

c-x 2: Divides the screen into two panes, with the cursor resting in the upper pane

c-m-v: Scroll down the lower pane (edit in one pane, useful when using another pane as a reference)

c-m-s-v: Scroll up the lower pane (CONTROL, META, and SHIFT Press V)

c-x o: Move the cursor to another pane

c-x 4 c-f: The found file appears in the lower pane, and the cursor jumps there

for more help :

EMACS provides commands to view the command documents, which begin with Ctrl-h.

c-h? : Emacs Lists what help it can provide

c-h C c-p: Emacs gives a brief description of this command (C-P)

c-h k c-p: Opens a new pane to display the name of the function and its document

c-h F previous-line<return>: Interpreting a function (Previous-line)

c-h v: Document showing Emacs variables (variables can be used to "customize Emacs Behavior")

c-h a: Related command Search (after entering a keyword, emacs lists the list of M-X commands that contain this keyword in all command names)

c-h i: Read the online manual (i.e., the usual Info)

The c-h I command will open a special buffer called "*info*", where you can read the software user manual. Click on M Emacs <Return> to read the user manual for Emacs. Press "?" Access to Info Guide. Emacs Info is our main reference document.
