Basic Vim Commands

Vim is an editor to create or edit a text file.

Two modes:

  • command mode: move around, copy and past
  • insert mode: insert text

Change mode from one to the other

From command mode to insert mode, type i/o(ou). From inset mode to command mode, type Esc.

Some useful commands for Vim. (Note: the following commands are only used in command mode.)

  • i Insert text before the current cursor position.
  • o(ou) Open up a new line following the current line and add text there.

  • h/l Moves the cursor one character to the left/right.
  • k/j Moves the cursor up/down one line.
  • nG/:n Cursor goes to the specified (n) line.
  • ^f/^b One page forward/backward.
  • $/0(zero) Move cursor to the end/beginning of current line.
  • w/b Move cursor forward/backward one word.

Yank is the copy command of Vim.

  • yw Yank from cursor to end of current word.
  • [n]yy Yank the following n lines (including the current line).

  • p Paste below cursor.

Search

  • /pattern Search forward for the pattern.
  • ?pattern Search backward for the pattern.
  • n/N After search, used for moving to the next search result (or reversely).
  • :g/pattern1/s//pattern2/g Replace every occurrence of pattern1 with pattern2.

Other Usefull Commands

  • u undo
  • ^r(Ctrl+r) redo
  • :set number Display line number.
  • :set nonumber Don’t display line number.

What’s more, most commands can be repeated n times by typing a number , n, before the command. For example, 10dd means delete 10 lines.

Set Vim for Python

If you want to write Python code in Vim, it is better to set ~/.vimrc (for Mac) to support Python syntax, indent, etc. For default, there is not such file in the HOME path. Just create one. For the content, refer to official configuration at here.
