Start electronics 
I have always used Vim to create web services. I have been using Vim for about two years now. As a reminder, I summarized the commands that I often use (but easily forget).
コンテンツ
1. Create a new tab
:tabe
2. Close the current tab
:tabc
3. start over
u
4. cancel
Ctrl + r
There is a big difference between knowing this and not knowing this.
5. Move the screen halfway down.
Ctrl + d
6. Move the screen halfway up.
Ctrl + u
7. Move to the first line
gg
8. Move to the bottom line
G
9. Delete and copy lines from the specified line
Type ms on the start line, me on the end line, and then the following command
:'s,'ed (削除) :'s,'ey (コピー)
This is quite useful.
10. Batch Replace in File
:%s/hoge/hoge2/g
Note that I often forget.
11. Change line break tag
When a file edited on windows is opened on a mac, there are times when it has strange line feed tags and the text has been packed. In such cases, this is the solution.
:set fileformat = mac :set fileformat = unix
This is also fine :set ff = mac :set ff = unix
