Vim command

This page is intended to be a manual for quickly finding commands, and a learning note for myself.
Just remember them and prictice them when you are coding.
Prictice makes perfect.

Mode Exchange

There are four modes in Vim and VScode-vim:

1. normal mode
2. insert mode
3. view mode
4. command mode
5. replace mode

From	To	Key
normal	insert	i, a, I, A...(many keys)
normal	command	:
normal	view	v, V
normal	replace	R
view, command, insert	normal	ESC

When using some editing instructions, it will also cause mode conversion.
