First and last lines

Oeasy teaches you to play VIM - 17 - # up and down

  • g gcorrespondingFirst line
  • GcorrespondingBiko
  • If the article is very long, it is very convenient to jump directly
  • OneGRight thereGround
  • If you want to go back to the beginning, you can use itg g

    • I don’t know why these two letters are particularly skilled
    • Skilled people heartache!
  • There is another combinationGo
  • For example, add a long configuration fileG o

    • GGo straight to the end
    • oInsert in the next line
  • Two keysGoget up
  • ctrl+cReturn to normal mode
  • ggJust go back to the beginning

    • Another game

Auto indent

  • Of course, it’s not all painful memories
  • g gmatchGIt’s the most convenient automatic indentation I’ve ever seen

    • g g = GAuto indent from first line to last line
    • This file may have 500 lines,
    • But it’s all indented at once
  • Not only programs, web pages, CSS and configuration files can be automatically tightened

    • In this way, the code is sorted very quickly
  • Programmers work in normal mode more often

    • Browse, search, skip, copy, paste
    • Really focus on writing code and then switch to the insert state.
    • Other editors always have only one insert state
    • In fact, it wastes a lot of keyboard functions
    • This is also normal mode, which is called normal mode

      • The reason why it is regarded as the default mode.
  • g g = GThis is great!!!
