Creating a custom modal

[0xayko]

Is it possible to create a modal like the native "delete" one?
I currently have this trash command:

cmd trash %{{
    printf "trash? [y/N] "
    read ans
    if [[ -z "$ans" || "$ans" != "y" ]]; then
        lf -remote "send $id reload"
        return;
    fi

    files=$(printf "$fx" | tr '\n' ';')
    while [ "$files" ]; do
        file=${files%%;*}

        trash-put "$(basename "$file")"
        if [ "$files" = "$file" ]; then
            files=''
        else
            files="${files#*;}"
        fi
    done
    lf -remote "send $id reload"
}}

Which works fine but I would prefer not having to type enter, and pressing escape doesn't cancel the prompt

@aayko I was playing with the flow proposed here: #1700
This is closest I could get so far:

map T &{{
	tmux split-window -l 1 '
		stty -icanon -echo
		echo -n "Trash files? [y/n] "
		key=$(dd bs=1 count=1 2>/dev/null)
		if [[ "$key" == "y" ]]; then
			while IFS= read -r file; do
				notify-send "Trashing file: $file"
			done <<< "'"$fx"'"
			lf -remote "send '$id' reload"
		fi
	'
}}

The solution requires you to have tmux installed, to know how to use it, and have lf started from tmux session like tmux new-session 'lf'. I could not find more elegant solution for taking single key that worked in tmux.
This is how it looks:

Just adding a note that % prompts are line buffered (to allow editing) so you have to press Enter at some point. This is mentioned in the documentation.

This is great thank you
