Going nuts..

It's most definitely legal to send two keypresses immediately at the press of one key, as long as there is no delay.

I don't agree. If your two sent keypresses perform a combination of actions in any single window that cannot be bound to a single key using WoW's in-game configuration, then they violate Blizzard's rules.

In other words, in any single WoW window, a hotkey is only allowed to perform a combination of actions that the same pressed key could trigger in that window using WoW's built-in key binding interface.
