Vim tips

A substitution with an empty search pattern replaces matches from the last search. After finding “foo” (/foo) in the file, you can replace all occurrences with :s//bar/. Source.

Neovim stores its data in this directories:

1
2
3
4

~/.config/nvim
~/.local/share/nvim
~/.local/state/nvim
~/.cache/nvim

• Use NeoVim’s inccommand option for live substitutions.
