Here's a tip: when typing Henry the Eighth, or World War Two, don't use the number 1. Use the capital 'i' instead: I.
So, instead of having Henry V 111 - which would be Henry version one hundred and eleven - type Henry VIII instead.
Instead of typing World War 11 - which would be World War Eleven (shudders at the thought of so many world wars!) - type World War II, or WWII.
