These keys were purposefully made difficult to hit!!
You need to hit them on the world map screen not only in the correct order, but also with the correct timing.
A short keypress is simply a quick click, noted with the symbol: "X" or "O"
A long keypress needs to be held for around 'half a second' and is denoted as:"=X=" or "=O="
