VIM Basics Beginner for personal use

VIM has six modes (but commonly used on three kinds of normal, insert, command line)
?
?
?

Normal mode
??? In normal mode, the editor commands, such as moving the cursor, deleting text, and so on. This is also the default mode after Vim is started. This is exactly the opposite of what many new users expect (most editor default mode is insert mode).

?
?
?? Vim's powerful editor can come from its normal mode commands. Normal mode commands often require an operator end. For example, the normal mode command DD deletes the current line, but the first "D" can be followed by a different move command instead of the second d, such as the "J" Key moved to the next line to delete the current row and the next row. You can also specify the number of commands to repeat, 2DD (repeat DD two times), and the DJ's effect is the same. Users learn a variety of text between the move/jump commands and other common mode of editing commands, and can be used flexibly combined, can be more efficient than those without the pattern of the editor for text editing.

In normal mode, there are many ways to get into insert mode. The more common way is to press a (append/append) key or I (insert/insert) key.
?
Insertion modes (insert mode)
?? In this mode, most keystrokes insert text into the text buffer. Most new users want this mode to persist throughout the text editor editing process.
?? In insert mode, you can press the ESC key back to normal mode.
??
?

Visual modes (visual mode)
? ????? This pattern is similar to normal mode. However, the move command expands the highlighted text area. The highlighted area can be a character, a line, or a piece of text. When a non-moving command is executed, the command is executed to the highlighted area. Vim's "text object" can also be used in this mode as the move command.
?
?
?
Selection mode (select modes)
??? This pattern is similar to the behavior of the modeless editor (the way Windows standard text controls are). In this mode, you can use the mouse or cursor keys to highlight the selection of text, but the input of any character, Vim will use this character to replace the selected highlighted text block, and automatically enter the insertion mode.
?
?
?
Command line mode
???? In command-line mode, you can enter text that will be interpreted and executed. For example, execute commands (: keys), search (/and keys) or filter commands (! Key). After the command is executed, VIM returns to the pattern before the command-line mode, usually in normal mode.
??
?
?
Ex modes (ex mode)
??? This is similar to command-line mode, where you can execute multiple commands at one time before using the: Visual command to leave the ex mode.

Vim can be followed by either the existing file you want to open or the name of the file that needs to be created.
Vim XXXX
?
?
?
In normal mode,
H is left, L right, J down, K on
W moves to the next with a space symbol carriage return, etc.
?
?
When entering insert mode
I edit at the current cursor
I Insert at the beginning of the line
A inserts at the end of A row
A inserts an edit after the cursor
o Insert a new row after the current line
O insert a new row before the current line
CW replaces the character (??) from the position of the cursor to the end of a word. Have the feeling that the verification can't use??? ）

Save the document in command-line mode or save to exit vim
Input from Normal mode: Enter command line mode, enter W and return to save the document.
or enter a W file name to save the document as a different file name, or to save it to a different path
?
?
?
Enter WQ in command-line mode to save and exit vim
Q! : Force quit, do not save

qw! : Force Save and exit
