Tips on VIM

Let's take 5 minutes to learn a few Vim shortcuts to improve work efficiency: d
A: insert at the end of the row
J: You can remove line breaks between the current row and the next row, that is, you can continue the next row to the end of the row.
~ : The characters at the cursor are case-insensitive.
ZZ: place the current row in the middle of the page for better reading
ZT: place the current row at the top of the page. It is very useful when reading function definitions.
CTRL-A: You can add 1 to the number where the cursor is located, and add a negative number and multiple digits to the supported range. You can use this shortcut key with macros to do a lot of things.
CTRL-X: If you add 1, you can subtract 1. It's smart!
