# 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>:wq<Enter>

# Quit without saving:
<Esc>:q!<Enter>
