Personnally I use bash, so I made so my history is eternal (as is the content never get deleted) and I use FZF_CTRL_R_OPTS to customize the ctrl-r of fzf.

Also the history is reloaded after each command so if I type multiple commands in a tmux pane x, and then go to another tmux pane y I just have to type something (just press the enter key) in pane y and I have the full history of what happened in pane x.

Here is how to do it, just add the following to your .bashrc for the eternal history :

```

  export HISTFILESIZE=
  export HISTSIZE=
  export HISTTIMEFORMAT="[%F %T] "
  export HISTFILE=~/.bash_eternal_history
  export HISTCONTROL=ignoreboth
  shopt -s histappend
  shopt -s checkwinsize
  filtered_history_save() {
      local last_command=$(history 1 | awk '{print $4}')
      # Don't store some commands in the history.
      if [[ ! "$last_command" =~ (mpv|pass|yt-dlp|wtwitch) ]]; then
          history -a
      fi
      history -c
      history -r
  }
  export PROMPT_COMMAND="filtered_history_save; $PROMPT_COMMAND"

```

And for the custom fzf ctrl-r :

```

  # Source fzf (should already be here if fzf is installed)
  if [ -f /usr/share/fzf/completion.bash ]; then
    . /usr/share/fzf/completion.bash
  fi

  if [ -f /usr/share/fzf/key-bindings.bash ]; then
    . /usr/share/fzf/key-bindings.bash
  fi


  # Customize ctrl-r
  export FZF_CTRL_R_OPTS="
    --preview 'echo {2..} | bat --color=always -pl sh'
    --preview-window right:wrap
    --bind 'ctrl-/:toggle-preview'
    --bind 'ctrl-t:track+clear-query'
    --bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort'
    --color header:italic
    --header 'Press CTRL-Y to copy command into clipboard'"

```
