• buffer
• cat

For kks-buffer script, I've changed the script to

preview_cmd="bat --color=always --line-range=:500"
history_file="$HOME/.cache/kks-buffers-history"

[ -f "$history_file" ] || touch "$history_file"

kks get '%val{buflist}' |
	grep -F "$*" |
	fzf --height 100% --highlight-line --prompt 'buf> ' --preview "kks cat -b {} | $preview_cmd" \

	while read -r name; do
    escaped_name=$(printf "'%s'" "$(echo "$name" | sed 's/ /\\ /g')")
    kks send buffer "$escaped_name"
	done
