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>
