When ESC/CTRL+C is pressed interrupt bootmenu and jump into U-Boot console. As the last entry in bootmenu is always U-Boot console just choose the last entry when ESC or CTRL+C is pressed.
ESC key is detected when either no other character appears after '\e' within 10ms or when non-'[' appears after '\e'.
It is useful when bootmenu is part of boot process and you want to interrupt boot process by scripts which control U-Boot (serial) console.
