4. Cancel Highlight Search

After using the find, want to cancel the highlight, I generally use two methods:

Use the command:

1. : Noh  

or search for a string that doesn't exist.

5. Commonly used folding commands

1. " collapse from cursor to 12 rows   ZD "      " manual"" marker "is valid  

6. Write code with VIM

VIM is a great editor for writing code because some of its features are designed specifically for programmers. Here are some of the commonly used:

]p: Similar to the function of P, but it automatically adjusts the indentation of the pasted text to fit the position of the current code. Try it! %: Match curly braces, brackets, brackets, and so on. At the top of a bracket, and then by%, the mouse appears in the other half of the matching brackets. >>: Indent All selected codes <<: Similar to above, but indent GD: reaches the definition of the function or variable where the cursor is located. K: In man, look for the word where the cursor is currently located.
