[Eighty Swords]

I'm by far no easy UO expert, but I think the concept is everytime you press one of the F6-F8 keys it executes one line at a time. For example if you make an EUO macro that says "Hello", waits 3 seconds then says "How are you?", the first time you press F8 it would only 'play' the first line of the macro (where you say "Hello"). If you press F8 again it would 'play' the 10 second delay, and if you press it one more time it would 'play' the "How are you?" part.

I think Canaris would be able to give more of an explanation. He seems to be our resident EUO expert
