macro_rules! move_up {

assert_eq!(formatc!("{'mu5}"), codes::move_up!(5));
assert_eq!(formatc!("{'md5}"), codes::move_down!(5));
assert_eq!(formatc!("{'mu}"), codes::move_up!(1));
assert_eq!(formatc!("{'md}"), codes::move_down!(1));

printcln!("{'clear}\n\nhello{'mu2}up{'md}down{'md}");

Result in terminal
