Search and replace
/word looks under the cursor for a string called Word. For example, in the file search Vbird This string, you can enter/vbird! Common
Word looks for a string above the cursor with a string name of Word.
NThis n is the English key. Represents "repeating the previous search". For example, if we just executed/vbird to search for Vbird this string,
When n is pressed, the next string that is named Vbird will continue to be searched downward. If the Vbird is executed, then pressing N will continue to search for the string named Vbird!
N This N is the English key. In contrast to N, the previous search for "reverse" is performed. For example/vbird, pressing N means "up" to search for Vbird.
: n1,n2s/word1/word2/g N1 and N2 are numbers. Look for the string word1 between N1 and N2, and replace the string with Word2!
For example, search for vbird between 100 and 200 rows and replace it with Vbird: ": 100,200s/vbird/vbird/g". Common
: 1, $s/word1/word2/gLook for the word1 string from the first line to the last line and replace the string with Word2! Common
: 1, $s/word1/word2/gc look for the word1 string from the first line to the last line, and replace the string with Word2! and display the prompt character before the substitution to confirm (confirm) if the user needs to be replaced! Common

Dd Delete the entire column where the cursor is located (common)
Ndd N is a number. Delete the down n column where the cursor is located, for example, 20DD to delete 20 columns (common)
d1g Remove all data from the first row of the cursor
Dg Remove all data from the last row of the cursor
