 * \t moves cursor to the end of autocompleted command
 * Esc[A (key up) and Esc[B (key down) navigates through history
 * Esc[C (key right) and Esc[D (key left) moves the cursor left and right

 If you run CLI through a serial port (like on Arduino with its UART-USB converter),
 you can use for example PuTTY (Windows) or XTerm (Linux).
