nvim

Neovim, a programmer's text editor based on Vim, provides several modes for different kinds of text manipulation. Pressing i in normal mode enters insert mode. <Esc> goes back to normal mode, which doesn't allow regular text insertion. See also: vim, vimtutor, vimdiff. More information: https://neovim.io.

  • Open a file:

nvim {{path/to/file}}

  • Enter text editing mode (insert mode):

<Esc>i

  • Copy ("yank") or cut ("delete") the current line (paste it with P):

<Esc>{{yy|dd}}

  • Enter normal mode and undo the last operation:

<Esc>u

  • Search for a pattern in the file (press n/N to go to next/previous match):

<Esc>/{{search_pattern}}<Enter>

  • Perform a regular expression substitution in the whole file:

<Esc>:%s/{{regular_expression}}/{{replacement}}/g<Enter>

  • Enter normal mode and save (write) the file, and quit:

{{<Esc>ZZ|<Esc>:x<Enter>|<Esc>:wq<Enter>}}

  • Quit without saving:

<Esc>:q!<Enter>
