Use :sort to sort selected lines alphabetically. (:sort u to remove duplicates; :sort! to sort desc, :sort n for numeric sorting)

package main

import (
    "bytes"
    "fmt"
    "bufio"
    "log"
    "os"
)

package main

import "fmt"

func main() {
	m := make(map[rune]int)
	var twos, threes int

	input := []string{"aabbffuuu", "zzaaafff", "ff"}

Use :[from],[to]s/[search]/[replace]/g to replace all occurrences of [search] with [replace] on the lines from [from] to [to].

BastianHofmann

Use :Ack --type [type] [pattern] to search for [pattern] only in files of [type] with ack.vim. Check available types with ack --help-types. E.g.: Ack --type js forEach.

BastianHofmann

Use *:Ack to search for the word under the cursor in the current directory with ack.vim.

Use gq to wrap the currently selected lines to the textwidth setting (gqq to wrap the current line and gqip to wrap the current paragraph). BTW: The vim-editorconfig sets the textwidth to the specified max_line_length.

Use b# to switch to the previous buffer (i.e. the file which was previously edited)

Use vim -oN to open VIM with N horizontal splits. Use vim -ON to open VIM with N vertical splits.

Edit multiple files in a row

You can open multiple files and edit them in a row (e.g. vim *.json or vim a.txt b.txt). Use :wn to write the current file and open the next.
