My ACM Vim memo

I. From command to zookeeper Mode

A: append is inserted after the current word.
I: insert Insert at the current position
O: insert open new line in a new row under the current row
A: append is inserted at the end of the current row.
I: insert at the beginning of the current row
O: insert open new line in the new row.
I, A, o, I, A, O, and I are more often used than workers. I am familiar with it in the future.

II. From zookeeper to command
ESC:

CTRL + [: it can achieve the same effect. Students with short fingers can use it instead of ESC.

3. Other commands in command mode
In the command mode, there is a lot of attention. These introductions are basically used to participate in high-speed programming, and need to be familiar with them.
In VI command mode, some are still in command mode after being pressed by volume, and some are modified by character or copy/paste.
Return to the command mode, and some do not change back to the text encoding mode.
Some operators will make special positioning for the content you originally wanted to change. For example, if you want to change a word, it will also take you to the simplified command mode.

File
: Q: Activate VI quit
: E xxxx Edit

R and R replace one character and replace the entire line of replace
U, u undo the last modification, undo the whole row
X and X cut down a character and cut back a character (based on backspace)

Handling of duplicates
. Refresh the zookeeper command or refresh

Many of the preceding commands can be combined by yourself,
There is a general rule that a single command is repeated twice for the whole line, followed by W for a word, and a number in the center is the number of repetitions.
For example, c5w can change five words and d3d can delete three rows.
For more information, see
Ce, 3x, 5dd, 10 W, D0, y $, 5g
