vim is different from Notepad or WORD. It is not possible to enter text after opening it. At this time, it is in normal mode.
There are 4 modes in vim:
• Normal-mode
• Insert-mode
• Command-mode
• Visual-mode
Normal mode
After starting vim, it is in normal mode by default. No matter what mode you are in, pressing the <Esc> key (sometimes you need to press twice) will enter the normal mode.
Insert mode
Pressing i, I, a, A and other keys in normal mode will enter the insertion mode. Now just remember that pressing the i key will perform the insertion mode. In insert mode, the corresponding characters are written when the key is pressed.
Command Mode
In normal mode, press the: (English colon) key and enter command mode. In command mode, you can execute some input and execute some instructions provided by vim or plug-in, just like in a shell. These instructions include setting the environment, file operations, calling a certain function, etc.
Commonly used commands are: q (exit), q! (forced exit), w (save), wq (save and exit).
Visual mode
Press v, V, <Ctrl>+v in normal mode to enter visual mode. The operation in visual mode is a bit like using a mouse to operate. When selecting text, there is a sense of visualization like mouse selection, which is sometimes very convenient.
The above article briefly discusses the four modes and mode switching of vim are all the content I share with you. I hope you can give you a reference and I hope you can support me more.
