fzf(Fuzzy File Finder) enhances the efficiency and convenience of your command-line workflow.

Installation of fzf

# Install the fzf itself by Homebrew
brew install fzf

# Install the auto-completion and the key bindings
# Add the .fzf.zsh which contains the configuration of these downloaded files to the .bashrc and the .zshrc
$(brew --prefix)/opt/fzf/install

• The .fzf.zsh file default contents are these below:
• key-bindings.zsh only contains CTRL-R, CTRL-T, and ALT-C

  # Setup fzf
  # ---------
  if [[ ! "$PATH" == */opt/homebrew/opt/fzf/bin* ]]; then
    PATH="${PATH:+${PATH}:}/opt/homebrew/opt/fzf/bin"
  fi
  
  # Auto-completion
  # ---------------
  [[ $- == *i* ]] && source "/opt/homebrew/opt/fzf/shell/completion.zsh" 2> /dev/null
  
  # Key bindings
  # ------------
  source "/opt/homebrew/opt/fzf/shell/key-bindings.zsh"

Link with NeoVIM

Installation(init.vim)

• If there is no fzf binary files have been installed before, We should install fzf separately in NeoVim(By Vim-Plug or something else).
  Otherwise, we could only specify the fzf pathname in our local drive which is enough.

  " If there is no fzf binary files before
  Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
  Plug 'junegunn/fzf.vim'
  
  " If fzf has been installed at the local drive
  Plug '/opt/homebrew/opt/fzf'
  Plug 'junegunn/fzf.vim'

Configuration(init.vim)

let $FZF_DEFAULT_OPTS="--height 40% --border --preview 'bat --style=numbers --color=always --line-range :500 {}'"

There are defined 3 keybindings(CTRL-f, CTRL-h, CTRL-c), and Ag was used software installed in our local drive called The silver searcher (GitHub - ggreer/the_silver_searcher: A code-searching tool similar to ack, but faster.)
