Binding keys in an mmorpg

[Arbaz]

Hey everyone. I'm totally new to this application so I have no clue what i'm doing.
I've been playing an mmorpg I need to bind some keys in it , for example F6, f7, f8, f9 All being pressed with just 1 single button. Since they're potion keys and its a pain spamming all 4 buttons (or more) .
So is there a way and is it possible? If so please guide me it would be very appreciated.

F1::Send {F6}{F7}{F8}{F9}
