trigger a foreground app by a script runnning in background (in same tty, linux)
I'ts near impossible to plan having a background task unexpectedly to take precedence over current TTY. Depending on what you're currently doing (editing some file with an editor), this may cause trouble!

how to use custom preview function for fzf command on zsh
If really, you could do something like: sfoo="$(declare -f foo)";sfoo=${sfoo#*\{} sfoo=${sfoo%$'\n\}'};fzf --preview "zsh <(echo '${sfoo%\}}') {}" (Feel free to replace zsh with bash! I've tested this with a more complex function, this work under bash and zsh!)

But from there, you have no advantage of running this as a function over simply running this as a script, ( by replacing foo() { by a shebang at 1st line... and drop last curly brace } at last line. )
