Practical vi Techniques

Although many places have iterated vi common commands, one may still come across with obstacles to maneuver comfortably.
The following is an ongoing list which I consider be worth recording and practicing.
  • Syntax Highlight (update your vim if this is not installed as default):
    sudo apt-get install vim
    :syntax on, :syntax off
  • Undo (one can undo multiple steps with the newer version)
  • Replace (refer advanced regex skills):
  • Search by keyword
  • Go to the first line, last line, head of line, end of line
    1G, G, 0, shift+4
  • Backward or forward by one word
    b, e
  • Go to line n
  • New line with input mode (on next line, on previous line)
    o, shift+o
  • Multiple lines cut-and-paste, copy-and-paste
    ndd+p, nyy+p
  • Copy-and-paste from clipboard (using the shortcut of terminal window)
    ctrl+shift+c, ctrl+shift+v
  • Set line number and unset
    :set nu, :set nu!
  • Save the file often, override even when complaining read-only permission
    :w, :w!
